In my experience, the trap attracts more beetles than it catches.
Nice try, buster. The last time somebody offered me some nice grubs, it took a week to get the damn radio collar off.
They’re leaving me alone this year, because it is cooler and wetter than normal. 
A couple of years ago it was a different story entirely: the effers were everywhere, eating plants and biting me. :mad:
Seems the University of Kentuckyagrees:
I suppose White Male Beatles are OK with you?
Racist!
Not quite sure why this is in the Pit, but anyway, we’ve (knock on wood) not seen too many of the dang things so far this year. Although, some of the volunteer tomato plants that I let go do have lacy leaves, so maybe they’re just hiding from me.
Seems like the traps could still be useful as flak. Put them near the plant you hate the most, or near the yard of the neighbor you hate the most, and distract them from the good stuff.
They are not Japanese beetles. They are Asia Pacific Islander beetles.
You racist.
ETA: Thanks, Zebra for stealing my thunder.
It appears you’ve been visited by the Japanese Beetle Fairy.
I had to do that.
I have. It works well, but it has drawbacks. For one, it only works on the grubs, so if you’re already infested with adult beetles, all you’re doing is preparing for next year. And you have to reapply it pretty often. But, it is effective against the grubs if you use it correctly.
Now that’s an ugly little fucker, ain’t it?
Racist!
It works but be sure to follow the instructions and apply it as many times as required. It takes a while to build up. I just wish I could get the whole block to use the stuff
It is cooler and wetter here and that is why I thought we were having more beetles than ever. I use rose dust and that helped until the rain washed it off. Now I have a Bayer product that is rain proof after one hour and is supposed to last for 30 days. So far there haven’t been any more…time will tell.
If it’s the Bayer product I think it is, it worked once, for maybe three weeks, and the next time I tried it the beetles were back chomping within a few days.
For some reason the Japanese beetles seem to have left/croaked/next generation burrowed into the ground early this year. I haven’t seen any significant numbers for a couple of weeks (usually they’re pestilential into early September).
V-JB Day in mid-August - I can live with that.
I’ve hated those buggers ever since I woke up early one morning in my bed because I felt something trying to tickle my lips to discover one of those THINGS crawling on my mouth. Bear in mind that when I sleep, I tend to breathe through my mouth and you’ll get a better understanding of the horror this induced.
I’ve hated almost everything with more than 4 legs ever since. shudder
Oh, so it’s not just a clever name.
