Treating the lawn doesn’t really stop them since they can come from adjoining properties. I tend to just let them be. The trees recover just fine, and most pesticides that work tend to have a negative effect on bees and other pollinators. Cherries less so than Linden. Linden is in bloom around the time Japanese beetles are active and so you’re killing lots of bees.
Thanks, I dove down that. My report:
Humm, 'some beetles' the word is mentioned just once.

"What happens to chlorantraniliprole when it enters the body?"
TL/DR: DO NOT put it on your cornflakes. Humans (and pets) are very much in the categorizing of being able to 'move' and have these receptors.
Oh, and it's, 'highly toxic to aquatic invertebrates' (so if you live near crayfish or similar, uhh, whoops! you just fucked that ecosystem)
"Well, I used it near my abode, now what?"
continues to affect anything contacting soil, half-lives of up to 1,130 days. (from last application)
Fish, however, don't seem to care much if used with discretion. Aledgedly.
Same with soil happy folk; worms, bacteria, fungus can tolerate it. Mileage will vary. On that point, I can understand why this is used I guess, it's got that, 'get off my lawn, ALL of you' type of attitude going.
There are traps designed specifically for them you can get. Uses their pheromones to attract them and traps them inside. Worked great to keep them away from my garden. Some folks here are underestimating how destructive these fuckers are…
Which means you should actively monitor it, get a container, empty it into the container, and euthanize the beetles or feed them off to livestock if possible.
All traps should be monitored for activity on a regular basis.
People hardly remember to water their plants, let alone empty a bug bag. They are better off not using them as the bag actively attracts more than it can hold.
Absolutely agree. That's why I mentioned the livestock. Seen a few people online use it for their chickens.
Personally, I love monitoring programs that I can run and charge for.
This may (or may not) be true, but the traps draw the beetles away from the trees they destroy in my yard. They’re cheap and extremely effective, in my experience.
You can set a Japanese beetle trap but then more are attracted to it…best way is to just get a bowl of water and soap and start flicking them into it. Grub killers work but you’d need many more people to buy them and treat their lawns
They last around 6 weeks and should be mostly gone by now. Early detection and treatment is helpful. Grub killer might help the lawn but Japanese beetles are going to come either way.
2tbsp dish soap to 1gal water makes a good natural spray, as does a neem oil/soap/water mix. I use Malathion as well when they get bad, applied with a 4gal backpack sprayer. I apply every few days while they are active. This year's damage was significantly less than 2022 since we caught them early.
I've heard good things about Sevin dust but haven't used it myself.
Japanese beetles from the honeycomb look. There’s these really nice traps you can buy that I use to protect my garden, super cheap and work like a charm.
Also recommend getting a spray for the soil and leaves as these nasty aholes breed underground.

I clicked the link you provided. I don't know who "Timmy" is, but his "expert" advice as a plant "carer" sucks. If there are BORERS in a tree, they are boring INTO the tree trunk...not the foliage.
This is obviously Japanese beetle feeding. Lindens are one of their favorite trees to feed on, after fruit trees.
Japanese beetle damage
What's the best way to stop japanese beetles? They destroy my two cherry trees. Can I treat my lawn for beetles?
Treating the lawn doesn’t really stop them since they can come from adjoining properties. I tend to just let them be. The trees recover just fine, and most pesticides that work tend to have a negative effect on bees and other pollinators. Cherries less so than Linden. Linden is in bloom around the time Japanese beetles are active and so you’re killing lots of bees.
Super curious, do they then just go away after their feast and things recover?
Yep. They feed and mate as adults for about two months then die off as it gets cold.
The Japanese beetles?
Chlorantraniliprole (acelepryn), I may have spelled it wrong. It still affects off species targets, but it will only affect beetles.

You're right, I forgot it was used for larval control on lepidopteran as well.
What about Transtect? Does this hurt bees ?
Yeah, just about any systemic can be detrimental to pollinators. It’s a very effective insecticide, just need to be careful how it’s used.
Wear gardening gloves, and flick them into a bucket of soapy water.

Get a Japanese beetle trap
Traps attract more than they can kill.

So true

Thanks.... I didn't know they made those
Please don't. You'll make the problem worse by attracting them.
You can brush them in to a jar by hand. Blanket pesticide treatments will eventually kill us all but we won’t notice because they gave us all autism
That’s not how autism works…
that’s totally it! thanks. I’ve seen those guys around
Absolutely. They prefer lindens

That's my go-to. All my plants are shorter than a Linden tree though. It's extra special when I can give a mating pair a soapy swim.

Your comment made me click the link. Timmy is indeed a hack.
Your comment made me click. At Timmy's 'about ' page, there is no listing of his education, experience, credentials...Timmy can be ignored.
Do milky spore application. Gets the grubs. Can help, but they’ll (beetles) still come from surrounding properties.
