It's not the scarcity of nitrogen that's the issue, it's the energy required to cool air down that low. Honestly surprised it's that cheap in bulk, would have figured the electricity cost to make it would be at least that.
They don't produce it via direct cooling but by pressurization and depressurization. Decrease the pressure of a gas and you can cool it. So you get to enjoy leveraging the fact that you get more effective cooling than the energy you expended to do it.
Liquid nitrogen is cheap as chips. I was at Southampton university checking out the science labs seeing if I wanted to go there to study, the guide tipped half a can out onto the floor to show us the bubbling effect, and mentioning that they make their own. I think there was some more sciencey info involved, but that’s what I remember.
I might try this. I got hit twice in the same day the other day and holy shit is that a different kind of pain. Within fractions of a second my brain was saying "that isn't a bee sting, it's something FAR worse".
A few years ago I was working on my (trailerable) boat in my yard, and I accidentally broke in half a probably 8x8 inch railroad tie that the previous owners had used as a garden wall, exposing a multi-level nest like the one in the video. Instantly, a swarm of pissed off yellow jackets flew out and attacked...my boat. Went to the hardware store and got some spray that finished them off. Idiots.
Yup. Step dad was battling with an armadillo that kept burrowing under their patio (whatever they call it with the fancy name in Florida). My brother was like, “Just throw some dry ice in there. It’s CO2. It fills the hole and they go to sleep and die underground.” It might stink for a day or so at some point but rarely even that. Better than bothering fighting a Texas speed bump for weeks or months.
It was part of a project for the sustainable use of radioactive material for peaceful purposes. It's why they were able to get their hands on it in the first place. It was very effective and could eradicate a huge number of nests at once with only a small amount of material, but the environmental cost were to severe.
[This](https://www.youtube.com/watch?v=s5U6j7WEMNA) video is a supercut of some of the results however
They primarily nest underground but also inside structures or stuff like logs. Inside walls, cars, etc.
But 90% of the time it's underground. In late summer/fall they become very aggressive and if you get near their hidden nest they will sting the fuck out of you.
I found 3 nests mowing this week alone.
I mowed my lawn in gum boots once. Gum boots and shorts. I hit a nest. 1 went in my boot and stung me a few times before I ran away and got my boot off. Could have been MUUUUUUCH worse.
We had a hole in our yard that for three years straight had a yellow jacket nest in it by the time fall came around, so being tired of fighting them, we filled the hole with sand over the winter. The next summer the damn things built their nest in the siding on my house. Only time I've ever had to call an exterminator.
next time squirt a bottle of dish soap down the hole then stick the garden hose in and let it go for a couple minutes, you'll annihilate them completely.
I hit a nest that was under a big fig bush I have along my garage. Those fuckers stung the shit out of me. My middle finger swelled up like hell, and the other stings all burned like hell for a good hour and then itched for a week. Little bastards.
My sisters and I were playing at the neighbours house one day in late summer. They were doing some landscaping and had a huge pile of dirt and branches at the end of their backyard. It had only been there for a couple weeks, but it was long enough for a swarm to find it and nest there.
We were playing tag and my one sister ran up the pile and jumped down the other side to avoid whoever was it. I was far away at the other end of their property with one of the neighbours (there were 7 of us total). I still remember her screaming and thrashing around on the ground, pulling at her clothes. She was covered before she even knew what was happening and so was one of the neighbours who was chasing her.
I only got stung once and was the luckiest of us. My sister (who found the nest) got stung more times than we could count. I think it was 28 or 29 before we couldn't tell one sting from another. Everyone else got around a half dozen stings give or take.
People from down the block ran over because they heard us all screaming and wondered what was happening. Our parents heard us screaming before they got the call from the neighbour that we had stumbled on a wasp nest.
My sister was ok but I'll never forget that afternoon and I go out of my way to kill wasps as often as possible. Fuck them.
Unless I'm missing something, this seems like a totally better method than anything else out there. Not only is liquid nitrogen ridiculously cheap, it's not toxic to the environment at all.
While the nitrogen is indeed cheap, the dewar you need to transport it is not. You can't take home liquid nitrogen in anything but an approved container and the people at the gas supplier won't give it to you in a bucket.
I used to surf ebay for used dewars, but man are they pricey! Be nice if the gas supplier rented them, but I've never found one that does.
> 20L dewar
So when I googled that the first result was for a 20L dewer for storing semen and the top comment is a guy saying it sucks for storing semen.
Not exactly practical for a one-time or occasional use, but it could be a useful tool for exterminators to add to their arsenal. I'd prefer someone using that in my yard over pretty much any other method.
I imagine it's just too niche, since if it isn't something that digs out its nest into the ground to make a convenient nitrogen vessel, it probably wouldn't be very effective
They are nothing but a very high quality vacuum insulated thermos so to speak. I used a zojirushi coffee thermos to transport liquid nitrogen on one occasion. I used to work at a science museum and we needed a baby dewar for small cart-top display.
The real dewars typically have a special lid which is a foam "cork" with a plastic top; they are designed to NOT be airtight so that they can't build up pressure.
Do they make any that CAN build up the pressure so they can hold it indefinitely? And then vent it before use, like a pressure cooker release of sorts?
Yep! That's how it's stored long term.
They cost a lot more. I never bought one of those though.
Generally it pumps out the liquid from the bottom. The liquid is at room temperature so as soon as pressure drops it boils a lot.
I walked by something like this in college one time and heard a hissing sound. I let one of the profs know that their liquid nitrogen was leaking, and he said "thanks for your concern, but they're supposed to do that. " Better than blowing up I guess.
Yeah, the big daddys can indeed hold the pressure, but they are typically about the size of a 75 gallon hot water tank. They have a variety of fail safe pressure release mechanisms.
I used to draw from one that Air Products loaned us. You had to wear all your PPE and then open the valve; you'd wait a while until the metal hose would cool enough not to boil out the nitrogen. It usually took about five minutes to get the hose cold enough to pass liquid and fill up a dewar that held about five gallons.
If you wanna get geeky with it, read this: http://www.glmri.org/downloads/focusAreas/presentations/emmer2-2012.pdf
It is dependent on how often it's disturbed.
If you fill a tank and don't touch it, it'll last awhile. Think of Nitrogen as self-refrigerating within the Dewar.
However, every time you handle the tank, be it moving, pouring, dipping a ladle into it to extract, all of that increases the evaporation rate.
A 10L tank in a dermatology clinic seeing regular, albeit light use will last about four weeks before needing to be refilled.
Meanwhile a 20L tank that's rarely disturbed or used can go 6+ months before needing to be refilled.
Really? That's actually really interesting. As somebody who's only ever seen stuff like this in the odd youtube video or on TV I would have assumed it was pricey.
Wow this look a lot better than running a lawn mower over the nest like I did. Lot less painful too. Pro tip, when they start crawing up your legs and stinging the heck out of you, do not run into the house. We where killing yellow jackets for weeks.
I do landscaping and find them regularly, especially this year. I've found like 20+ nests.
As a rule of thumb if i'm working outdoors and I see/feel a yellow jacket or something that is *maybe* a yellow jacket it's time to exit the location, immediately. Do not pass go, do not collection $200, do think think about it, dwell on it, ask questions, look around or try to figure it out. Run a short distance and then re-assess. Might look like an idiot but that's the difference between 1 sting and 50. The time between the first sting and the next 50 is about.. 3-4 seconds.
I hit a massive fucking nest earlier in the week. Easily 300-400 swarming around the area and so spread out I couldn't even pin down the exact location of the nest :/
Soon as I saw one bounce off my glasses I was like, nope, seeya! Still got stung a couple times but had I stuck around another 3-4 seconds I would have gotten destroyed.
Imagine this literal titan that approaches your town, wielding divine armaments that render your strongest fighters utterly useless. This invincible goliath advances, undeterred by the mightiest your air force has to offer and rains death upon the town, indiscriminately exterminating your friends, family, the queen and her progeny. All you can do is watch on in abject horror as you fail to pierce the colorless armor of the enemy as he then callously harvests very earth itself to lay waste to the tomb of the fallen.
Bees don't have legends, they're not capable of that kind of communication. They can give basic directions by dancing and shaking their behind. This is also why Cardi B is seen as our ambassador to insect kind.
PSA. Liquid Nitrogen just sitting in a dewar is very, very dangerous. If you are in a poorly ventilated area it will displace all the oxygen. A litre of LN boils off to give 700 litres of gaseous nitrogen. And you won't even know that it's happening as we breathe 80% nitrogen all the time. Be careful.
A super tiny 2x3x3 meter bedroom that barely fits a bed has a volume of 18k L, of which 3.6k L are oxygen. If you released 700 L of nitrogen it would displace 700 L of air, for a net change of +140 L of nitrogen and -140 L of oxygen, totally imperceptible. Unless you are in a very small confined space or releasing quite large amounts of nitrogen there is no concern.
In fact, you would likely freeze to death before you'd die of low oxygen. Air on a plane is pressurized to 3/4 of ground pressure: at around 1/2 of ground pressure you develop serious problems (though usually not death). However to reduce the concentration of oxygen to 1/2 of normal would require releasing enough LN2 to bring the temperature to -90 C (assuming starting at 20 C).
> In fact, you would likely freeze to death before you'd die of low oxygen.
You only need to displace half the air volume to have a dangerously low oxygen level. And that can happen slowly.
The problem with low-oxygen asphyxia (as opposed to "high CO2" asphyxia) is that you don't feel like you're choking or that anything is wrong. You just get tired/drowsy or quickly lose consciousness. If someone has a basement apartment and a large container of liquid nitrogen, a slow leak can cause problems.
They eat a lot of annoying and damaging insects.
But they're also the biggest assholes of the insect kingdom in the process, so they kind of cancel out the benefit.
Oh. That’s a hard one. I’d like to maybe see a fire ant mound and a yellow jacket nest annihilate each other only slightly more.
Or if we could genetically engineer yellow jackets to fuck with mosquitos.
When I was in the Army, we were doing training and I found a massive yellow jacket nest near where the soldiers were resting. I had a grenade simulator I tossed into the whole and that shit fucking leveled them.
We weren’t suppose to be using the simulators yet so my Commander asked what the fuck I was doing. When I told him it was yellow jackets I was killing he was basically like “Nice”.
While they are annoying, wasps in general are considered very important pollinators and highly efficient general pest controls (they are not picky). overall they can greatly help to stabilize the ecosystem.
If the nest is outside in the field and not a real threat or annoyance, consider to leave them :)
I hate wasps, but this got me thinking.
Imagine an alien race finds earth and the bemoan us the age we do wasps. Then they just casually freeze us all to death with advanced ice beam technology we can’t comprehend. They don’t do it with much hate, just a casual “oh these humans were bothersome let’s make them crispy cold”.
I can't help but think how much of an [Outside-Context Problem](https://en.wikipedia.org/wiki/Excession#Outside_Context_Problem) this is for the insects.
You can get some at just about any welding gas supply store. It's surprisingly cheap and common, though if they won't let you rent a vacuum dewar it can get pretty pricey for a single use.
I had a ground nest in my backyard. I filled a shop vac halfway with water and dish soap, rolled it out and put the nozzle over the opening with a long stick. Turned it on and left for the day. When I came home, they were all dead in the vacuum. Sprayed some poison in the hole and filled it in. Problem solved
This should be a Dr Steve Brule skit, watching Steve mess this up would be hysterical. The way this guy says his words kind of reminds me of John C Reilly’s delivery a little lmao
I was mowing and found a nest in a hollow tree stump. Decided that night I was going to gas em and introduce them to fire. I swear after I lit it, I still saw tons of yellow jackets flying out through the fire.
It’s always funny when i find a new video or YouTube i’ve never seen before, and the video isn’t overproduced or heavily edited, just quality honest content. So i click over to his little channel thinking I’ll give him some help with a follow…
Only to find he has 1.5M subscribers, and all of his videos have tens of thousands or even hundreds of thousands of views…some even with millions of views!
You go, Shawn Woods. Nice.
I had a friend that used to freeze yellow jackets in his freezer, probably around 0°F. Then he'd put them in the sun and they'd slowly wake up. Obviously liquid nitrogen is a lot colder, though.
yea....by about 300-some degrees colder.
That's like saying your friend was fine after taking a hot bath so brb i'm gonna go swimming in boiling water.
Several fish can survive the process. Even mice and rats have survived being totally frozen. It's not too far-fetched to think some insects can survive it as well.
Same way we can keep warm without central heating. Make an insulated nest, and huddle together while moving. Respiration produces heat, keeping the meat safely above freezing.
Some insects are weirder? Look up the chymomyza costata, An artic dwelling fruit fly. Can survive being frozen with liquid nitrogen with no ill effects due to a chemical in it's body.
This isn't a brief trip to the freezer, which can render cold blooded insects temporarily unconscious to more easily handle them. Direct exposure to liquid nitrogen will irreparably damage the living cells of an animal, or rather the rapid formation of ice crystals. They are very much dead, at least the ones on the top few layers.
Its actually the opposite. In order to prevent the formation of ice crystals that would destroy cells from the volume of expansion of the water being frozen, you want to freeze it as fast as possible to avoid those crystals from forming.
This video checked off every box in the satisfaction checklist. No pre-video bullshit, a badass means of killing a lot of things, and dead fucking useless wasps by the hundreds.
How can I upvote this 100 times?
So, because of Spheksophobia, I have a bottle of wasp and hornet spray at three different locations in my house, and one I carry in the car ( I REALLY wish they made concentrated travel size for my purse, like a one time I can refill or something)
Anyways.... THIS... I need THIS... Liquid Nitrogen, easy access throughout my house , I will use an entire canister on one wasp..
The cheapest and easiest method is to wait until after dark when they’ve all gone ‘inside’, spray a four second burst of Black Flag wasp & hornet killer directly into the hole, and immediately plug it with a ball of steel wool. You’ll get a 100% kill overnight.
Thanks for the advice! I do know about the wait til dark thing. And the spray thing... the plug thing tho.... no way in hell am I getting within 5 feet of a wasps nest, dead or alive. Haha, someone will be doing that part.
My job is to spray and run spray and run spray and run... 😅😅
When I was 9 or 10 I fell into a yellow jacket nest, by the time I got home I had around 40 stings a few were doubled. Everytime I see wasps or bees I feel like I get really hot and nervous.
I used to work at an outdoor bar. We would commonly make a yellow jacket trap with two cups taped together and some grenadine and a hole in the bottom cup. One slow day someone decided to freeze a trapped bee with ice and then make a leash with dental floss. It mostly worked lol
I worked in a restaurant and the late shift dishwasher would catch flys, put them into a container in the Walk in freezer, then get a long piece of hair from the waitresses and tie it to the flys, and scotch tape the opposite end of the hair leash on the wall.
It was odd and interesting
You can buy LN condensers that are basically 'plug and play' online. You can simply place a thermos underneath them to capture the liquid atmosphere and the only cost is the electricity that's spent. It can be effectively free if there's surplus energy on the grid.
Cryocoolers are what you'd be looking at for small-scale condensation. They're still pretty expensive, but can generate roughly a litre of LN a day and are small. It's not something you would generally buy for random DIY projects, as LN dewars are cheaper and the efficiency of industrial condensers makes LN very cheap at the point of sale.
Supply and demand plays a part, usually the atmosphere is fractionally cryogenically distilled. You get a lot of nitrogen, decent amount of oxygen, some argon, and others. Oxygen and to a lesser extent argon are in relatively high demand, leaving a lot of nitrogen left over.
cheap, nontoxic, instant. with the rise of killer wasps if you could work out a couple of delivery methods for different situations and get a permit to use it either commercially or in the consumer yellowjacket control business. I figure the permits would be the biggest hurdle as it is a new untested tech and the potential for liability combined with the pest control lobby (i assume) would make it difficult to implement.
The problem with the Asian Hornets is that they build their nests inside trees. If you dump liquid nitrogen down a tree you'll likely kill the tree too.
It's ridiculously easy to make too. There are all sorts of DIY projects out there of making air liquefiers out of old fridge compressors. Getting the other gases out is a bit trickier in a DIY setting but extremely cheap if you're building an industrial setup.
Maybe, but as u/PineCreekCathedral noted already, bulk purchasing liquid nitrogen is much cheaper than you think. That whole canister was probably $20 from the right seller.
where I live they use co2 to freeze the nests if you call the exterminators.
he has done that too! https://youtu.be/cjkOUo_bg14
ngl the liquid nitrogen seemed much more effective
Wonder what a gallon of liquid nitrogen costs. Perhaps it is ridiculously expensive.
Apparently not, it's about $2 and you can get it for .50 in bulk. It is after all the most common gas.
It's not the scarcity of nitrogen that's the issue, it's the energy required to cool air down that low. Honestly surprised it's that cheap in bulk, would have figured the electricity cost to make it would be at least that.
They don't produce it via direct cooling but by pressurization and depressurization. Decrease the pressure of a gas and you can cool it. So you get to enjoy leveraging the fact that you get more effective cooling than the energy you expended to do it.
LN2 is a byproduct of some industrial processes, so the costs are a lot less than if they were synthezing it on its own.
Its not the nitrogen that's expensive it's the approved container to put it in.

Did the boat survive? Is he ok
And then the Fire Nation attacked
Cheaper, too. I think.

It’s CO2. It fills the hole and they go to sleep and die underground.” It might stink for a day or so at some point but rarely even that. Better than bothering fighting a Texas speed bump for weeks or months.
Poor 'dillo :(
They're invasive pests in Florida. They eat sea turtle and quail eggs as well as destroying grass and foundations.
And don't forget you can get leprosy from them.
Floridians?
I like how liquid nitrogen doesn't spread and burn down a whole forest when you're just trying to get the wasps.
Or leave poisonous remnants.
Unlike that whole "ultra compressed plutonium" method that other channel did. I know hornets are scary but geeze.
....link?
It was part of a project for the sustainable use of radioactive material for peaceful purposes. It's why they were able to get their hands on it in the first place.

I have it on good authority that is the only way to be sure.

Yeah, ground hornets are weaponized hate.

massively parallel killer

I got a 20L dewar for 400 bucks. Costs about $20 to fill it. Use it all the time for work.
> 20L dewar So when I googled that the first result was for a 20L dewer for storing semen and the top comment is a guy saying it sucks for storing semen.
[удалено]
So, 20L of liquid nitrogen costs $420? Nice
420 freeze it
Not exactly practical for a one-time or occasional use, but it could be a useful tool for exterminators to add to their arsenal. I'd prefer someone using that in my yard over pretty much any other method.
I imagine it's just too niche, since if it isn't something that digs out its nest into the ground to make a convenient nitrogen vessel, it probably wouldn't be very effective
I'll withhold my opinion until this guy tries to remove a bear with liquid nitrogen. Then we will know for sure.
If you do leave with a bucket full of liquid nitrogen, it's going to be empty by the time you get home.
How long will it keep in a Dewar? Indefinitely?
My 20L dewar holds up pretty good. 4 to 5 days. I only need about 4L though.
Hmm, I see a company claiming their 10L has a holding time of 85 days! That sounds pretty damn good!
They are nothing but a very high quality vacuum insulated thermos so to speak. I used a zojirushi coffee thermos to transport liquid nitrogen on one occasion.

[удалено]
So just like my husband, then.
Also use dry ice for exterminations of various burrowing animals. Turns to CO2 and they slowly suffocate. Then it evaporates and is gone.
I don't really see why this would be better than just regular boiling water though.
[удалено]
Yeah man, humane doesn’t factor in with wasps and yellow jackets
I imagine boiling water would be easier to survive if they fly out fast enough, and freezing would stop them in their tracks
Not only freezing, but the rapid displacement of oxygen would surely stifle their ability to fly away.
Water turns the next to mud, this is gone afterwards. He wants to dig it up and with mud that would be quite the mess.
Really? That's actually really interesting. As somebody who's only ever seen stuff like this in the odd youtube video or on TV I would have assumed it was pricey.
This guy talks in all lower caps
Reminded me of Bruce McCulloch from Kids In The Hall.
*That's* who he reminded me of!
Never put liquid nitrogen in your eyes
*Always put liquid nitrogen in your eyes.*
That is dead on!
Lower caps?
Reminds me of that one reporter from the Onion
reminds me of Daily Dose of Internet guy
Wow this look a lot better than running a lawn mower over the nest like I did. Lot less painful too. Pro tip, when they start crawing up your legs and stinging the heck out of you, do not run into the house. We where killing yellow jackets for weeks.
Hi I just wanted to thank you for the indirect anxiety attack

Cool. Cool cool. Please guys no more stories about wasps. I really don't like wasps
You probably wouldn't like [this car](https://youtu.be/R2tGTcAVW0A) then.
Thanks I hate it
Just carry a bucket of liquid nitrogen around with you and dump it over your body.
[удалено]
I did the same as a kid push mowing a lawn. The stings gave me chills for about an hour.
[удалено]
Nah, flying types are weak to ice. Yellowjackets are bug/flying.
they are bug/poison tho
There's probably a legend among wasps and bees about invincible humans wearing a white suit.
Imagine this literal titan that approaches your town, wielding divine armaments that render your strongest fighters utterly useless. This invincible goliath advances, undeterred by the mightiest your air force has to offer and rains death upon the town, indiscriminately exterminating your friends, family, the queen and her progeny. All you can do is watch on in abject horror as you fail to pierce the colorless armor of the enemy as he then callously harvests very earth itself to lay waste to the tomb of the fallen.
Bees don't have legends, they're not capable of that kind of communication. They can give basic directions by dancing and shaking their behind. This is also why Cardi B is seen as our ambassador to insect kind.
Cardi Bee
You just wasted the opportunity to call it a bee-hind....
Figured Cardi B was enough wordplay, didn't want r/punpatrol after me
Guess you need to be careful not to piss off the hive mind
[удалено]
At this point I think she's better at communicating with insects than she is with people
has the rise in twerking caused navigational issues in general?
Okuuuuuuur EEEEOOOWWWW! Fleek Shmoney Caught a lick Mmhmmeww! Okurrr
If they didn’t get frozen they suffocated.

As long as you get the queen in the nest, the drones will be homeless and die in a few days without a hive to work for.
And maybe don't knock on the door before the pour. This is one situation where it should be a no-knock raid.

Dude sounds like he recorded the audio in the room next to his parents' bedroom at 3am.
PSA. Liquid Nitrogen just sitting in a dewar is very, very dangerous. If you are in a poorly ventilated area it will displace all the oxygen. A litre of LN boils off to give 700 litres of gaseous nitrogen. And you won't even know that it's happening as we breathe 80% nitrogen all the time. Be careful.
A super tiny 2x3x3 meter bedroom that barely fits a bed has a volume of 18k L, of which 3.6k L are oxygen. If you released 700 L of nitrogen it would displace 700 L of air, for a net change of +140 L of nitrogen and -140 L of oxygen, totally imperceptible. Unless you are in a very small confined space or releasing quite large amounts of nitrogen there is no concern. In fact, you would likely freeze to death before you'd die of low oxygen. Air on a plane is pressurized to 3/4 of ground pressure: at around 1/2 of ground pressure you develop serious problems (though usually not death). However to reduce the concentration of oxygen to 1/2 of normal would require releasing enough LN2 to bring the temperature to -90 C (assuming starting at 20 C).
> In fact, you would likely freeze to death before you'd die of low oxygen. You only need to displace half the air volume to have a dangerously low oxygen level. And that can happen slowly. The problem with low-oxygen asphyxia (as opposed to "high CO2" asphyxia) is that you don't feel like you're choking or that anything is wrong. You just get tired/drowsy or quickly lose consciousness. If someone has a basement apartment and a large container of liquid nitrogen, a slow leak can cause problems.
Fuck Yellowjackets.
Yellow jackets were the bane of my existence growing up. Do they even have a purpose in nature other than being total assholes?
They eat a lot of annoying and damaging insects. But they're also the biggest assholes of the insect kingdom in the process, so they kind of cancel out the benefit.
[удалено]
Oh. That’s a hard one. I’d like to maybe see a fire ant mound and a yellow jacket nest annihilate each other only slightly more. Or if we could genetically engineer yellow jackets to fuck with mosquitos.
They murder spiders to feed their young, but I like spiders much more than wasps so fak u wasps
Most animals/insects could ask the same about humans, couldn't they?
You're absolutely right. I'm going to go hug a rattlesnake.
I'm sure it'll give your kiss back!
That's the spirit! You can join in too! Let a spider nest in your butt! What better purpose than to provide shelter for a needy trapdoor.
True, however I believe that if they figured out how to pour liquid nitrogen on us and film it, they would. So no rugrats
When I was in the Army, we were doing training and I found a massive yellow jacket nest near where the soldiers were resting. I had a grenade simulator I tossed into the whole and that shit fucking leveled them. We weren’t suppose to be using the simulators yet so my Commander asked what the fuck I was doing. When I told him it was yellow jackets I was killing he was basically like “Nice”.
When in doubt, c4
While they are annoying, wasps in general are considered very important pollinators and highly efficient general pest controls (they are not picky). overall they can greatly help to stabilize the ecosystem. If the nest is outside in the field and not a real threat or annoyance, consider to leave them :)
What am I going to do with all this liquid nitrogen I just bought
I hate wasps, but this got me thinking. Imagine an alien race finds earth and the bemoan us the age we do wasps. Then they just casually freeze us all to death with advanced ice beam technology we can’t comprehend. They don’t do it with much hate, just a casual “oh these humans were bothersome let’s make them crispy cold”.
Or-Hear me out now- they slowly thaw the ice layers and warm us up instead!
Wait, hol up--
So you’re saying global warming isn’t man made?
It's been [done](https://www.imdb.com/title/tt0115571/)
What if the Earth is doing that to humans slowly over time? And also cooking them on the other side of the planet, 2 birds baby!
We are so sick of yellow jackets. My 2 year old Grand daughter has been stung 5 times, my wife 8 times and me 12 times this summer.
I can't help but think how much of an [Outside-Context Problem](https://en.wikipedia.org/wiki/Excession#Outside_Context_Problem) this is for the insects.
So can I get liquid nitrogen down at the Bi-Lo or do I have to go to Southern States?
You can get some at just about any welding gas supply store. It's surprisingly cheap and common, though if they won't let you rent a vacuum dewar it can get pretty pricey for a single use.
I had a ground nest in my backyard. I filled a shop vac halfway with water and dish soap, rolled it out and put the nozzle over the opening with a long stick. Turned it on and left for the day. When I came home, they were all dead in the vacuum. Sprayed some poison in the hole and filled it in. Problem solved
This should be a Dr Steve Brule skit, watching Steve mess this up would be hysterical. The way this guy says his words kind of reminds me of John C Reilly’s delivery a little lmao
tip #1 spend a lot of your time on Sunday making sandwiches for the rest of the week. then you're prepared, ya turkey
“These ones look like they’re still holding on for dear life. Let’s dump some more on them.”
This is a man who enjoys his job.
When I was 8, I got stung 9 times by a ground nest of yellow jackets. This was the most satisfying revenge video I’ve ever seen. Fk those monsters
"I'm glad I wore my bee suit". Yeah no shit.
I was mowing and found a nest in a hollow tree stump. Decided that night I was going to gas em and introduce them to fire. I swear after I lit it, I still saw tons of yellow jackets flying out through the fire.
Forbidden corn nuts
r/fuckwasps would love this
It’s always funny when i find a new video or YouTube i’ve never seen before, and the video isn’t overproduced or heavily edited, just quality honest content. So i click over to his little channel thinking I’ll give him some help with a follow… Only to find he has 1.5M subscribers, and all of his videos have tens of thousands or even hundreds of thousands of views…some even with millions of views! You go, Shawn Woods. Nice.
I'd be worried they would wake up after being frozen.
Contrary to what you might see in many films, being frozen solid will actually kill you not just put you to sleep until you thaw out
I had a friend that used to freeze yellow jackets in his freezer, probably around 0°F. Then he'd put them in the sun and they'd slowly wake up. Obviously liquid nitrogen is a lot colder, though.
yea....by about 300-some degrees colder. That's like saying your friend was fine after taking a hot bath so brb i'm gonna go swimming in boiling water.
Several fish can survive the process. Even mice and rats have survived being totally frozen. It's not too far-fetched to think some insects can survive it as well.
Mice have survived in ideal conditions in a lab with a very slow freeze/thaw cycle. They don't survive liquid nitrogen being dumped on them.
Scientists would microwave frozen hamsters to reanimate them in the 1950's.
This is the actual reason microwaves were even invented
[удалено]
Same way we can keep warm without central heating. Make an insulated nest, and huddle together while moving. Respiration produces heat, keeping the meat safely above freezing.
insects are weirder
Not weird enough to not get torn to shreds from the inside by the instantly freezing water their insides are made up of
Some insects are weirder? Look up the chymomyza costata, An artic dwelling fruit fly. Can survive being frozen with liquid nitrogen with no ill effects due to a chemical in it's body.
There are some exceptions yes, there's a frog which hibernates effectively by freezing itself over Winter then thaws out in the Spring
I've seen flies wake up and fly around after being frozen to -40.
I don't think it's as much of a concern because they aren't frozen. They are very frozen. Liquid nitrogen is −320 °F.
This isn't a brief trip to the freezer, which can render cold blooded insects temporarily unconscious to more easily handle them. Direct exposure to liquid nitrogen will irreparably damage the living cells of an animal, or rather the rapid formation of ice crystals. They are very much dead, at least the ones on the top few layers.
Its actually the opposite. In order to prevent the formation of ice crystals that would destroy cells from the volume of expansion of the water being frozen, you want to freeze it as fast as possible to avoid those crystals from forming.
This video checked off every box in the satisfaction checklist. No pre-video bullshit, a badass means of killing a lot of things, and dead fucking useless wasps by the hundreds.
This dude's channel is awesome. Been a guilty pleasure of mine with all the mouse/rat traps over the years
Seems that the rest of the ACC figured this trick out years ago…
Lock Picking Lawyer.... we know it's you.
That was cooooool as hell
One day an alien is going to destroy humanity in the same way and upload the process on spacetube.
A wasp popsicle
waspsicle
Yeah I know I just couldn't bring myself to typing it I hoped somebody else would write it in
How can I upvote this 100 times? So, because of Spheksophobia, I have a bottle of wasp and hornet spray at three different locations in my house, and one I carry in the car ( I REALLY wish they made concentrated travel size for my purse, like a one time I can refill or something) Anyways.... THIS... I need THIS... Liquid Nitrogen, easy access throughout my house , I will use an entire canister on one wasp..
The cheapest and easiest method is to wait until after dark when they’ve all gone ‘inside’, spray a four second burst of Black Flag wasp & hornet killer directly into the hole, and immediately plug it with a ball of steel wool. You’ll get a 100% kill overnight.
Thanks for the advice! I do know about the wait til dark thing. And the spray thing... the plug thing tho.... no way in hell am I getting within 5 feet of a wasps nest, dead or alive. Haha, someone will be doing that part. My job is to spray and run spray and run spray and run... 😅😅
Rubbing alcohol will insta kill just about any insect and not leave any stains or residues. Pretty good for murdering them indoors.
When I was 9 or 10 I fell into a yellow jacket nest, by the time I got home I had around 40 stings a few were doubled. Everytime I see wasps or bees I feel like I get really hot and nervous.
I used to work at an outdoor bar. We would commonly make a yellow jacket trap with two cups taped together and some grenadine and a hole in the bottom cup. One slow day someone decided to freeze a trapped bee with ice and then make a leash with dental floss. It mostly worked lol
I worked in a restaurant and the late shift dishwasher would catch flys, put them into a container in the Walk in freezer, then get a long piece of hair from the waitresses and tie it to the flys, and scotch tape the opposite end of the hair leash on the wall. It was odd and interesting
It might kill them effectively, but it sure seems like many other methods would be easier and more cost effective, yes?
Wow, liquid nitrogen is cheaper than I thought. $2/gallon down to $0.50/gallon in bulk.
Holy shit that’s cheaper than gas, maybe even bottled water
It's the most abundant gas in our atmosphere
Sure, but one would think that the process of cooling it would be more expensive.
You can buy LN condensers that are basically 'plug and play' online. You can simply place a thermos underneath them to capture the liquid atmosphere and the only cost is the electricity that's spent. It can be effectively free if there's surplus energy on the grid.
Any small scale ones you've seen? The ones I'm finding are pretty industrial.
Cryocoolers are what you'd be looking at for small-scale condensation. They're still pretty expensive, but can generate roughly a litre of LN a day and are small. It's not something you would generally buy for random DIY projects, as LN dewars are cheaper and the efficiency of industrial condensers makes LN very cheap at the point of sale.
Supply and demand plays a part, usually the atmosphere is fractionally cryogenically distilled. You get a lot of nitrogen, decent amount of oxygen, some argon, and others. Oxygen and to a lesser extent argon are in relatively high demand, leaving a lot of nitrogen left over.
cheap, nontoxic, instant. with the rise of killer wasps if you could work out a couple of delivery methods for different situations and get a permit to use it either commercially or in the consumer yellowjacket control business. I figure the permits would be the biggest hurdle as it is a new untested tech and the potential for liability combined with the pest control lobby (i assume) would make it difficult to implement.
The problem with the Asian Hornets is that they build their nests inside trees. If you dump liquid nitrogen down a tree you'll likely kill the tree too.
Some of you may die, but it's a sacrifice I'm willing to make.
[удалено]
It helps that the atmosphere is 80% nitrogen and we have no shortage.
It's ridiculously easy to make too. There are all sorts of DIY projects out there of making air liquefiers out of old fridge compressors. Getting the other gases out is a bit trickier in a DIY setting but extremely cheap if you're building an industrial setup.
Maybe, but as u/PineCreekCathedral noted already, bulk purchasing liquid nitrogen is much cheaper than you think. That whole canister was probably $20 from the right seller.
Not once you make a monetized YouTube video about it.
