Nice looking crop of pears! Those traps look like a good idea. I haven’t had the beetles for several years since I used a big bag of Grubex throughout my orchard area. Knock on wood.

Had more bag traps than buckets, so I hung 2 in the center of the hazelnut grove where my americana X row has larger trees. I modified the bottom of the bags so I can empty in a larger bag, and reuse.
I cut a section off the bottom and use clothes pins to seal off.

Do they hit your hazelnuts? The japanese beetles here go after my cherries and plums first; they barely touch anything else.

For me my Hazelnuts are one of the Japanese Beetles most preferred trees, along with my Cherry and Apples

Yep, they love the hazelnut. Along the edges I also patrol trees that have them congregated and nudgenthem into a wide mouthed container. They love being there bunched up together and dont fly out

Wow, interesting. Good info since I’m putting in some hazelnuts this fall.
They do not bother my apple trees; they engage in “activities” on them, but I rarely see feeding damage.
I used to use neem with some result but have had better success with Surround this year. I have yet to try a trap.

30 gallon traps have been working quite well. I have placed 3-4 softball sized and larger stone to keep them from blowing over. Only one blew over and I zip tied it to a fence. The other ones feel quite heavy and now have some rain in them too. Thinking of using some soapy water with pyrethrins as a “treatment” before I empty soon.

Instead of the pyrethrins treatment I am loving tossing them into the pond. Even the turtles are in on the feast.
Those whiite dots on the water are whats left of the bugs. 2" deep in a 5 gal

You know the trick the old timers taught me of having a light near the water to feed the fish at night with light seeking insects. Solar light duct taped to a fence post about 2 feet from the water works great. On the beetles lure them down to the pond and leave a 5 gallon bucket cut open at the bottom they fall into. Then duct tape the bucket to the post with a scent lure on top. It might work pretty good!

The year of the 17 year locus some of my fish gained double the weight they should have.
It is all worth doing!

Some fish readily eat plants like duckweed as well eg. Bluegill and tilapia

I did the same thing yesterday morning. Mostly just bluegill and catfish in my pond.

Try mixing in about a table spoon of citric acid and a teaspoon of detergent. The acid will preserve the bodies and the detergent will make it easier to rinse off the trash can.
I just wonder if anyone has succeeded in controlling them by trapping. I’ve long assumed it didn’t work for J. beetles based on my experience with small commercial traps, but maybe the more industrial approach would work.

I’ve wondered the same. I just have a few bag ones out for free chicken and fish food. I keep them far away from my plants so they want draw them in.
This year I’ve tried dusting them with diatomaceous earth but I had been getting the feeling that it wasn’t having an impact. I then started capturing them in a container full of diatomaceous earth and checking in on them to see how long it takes for them to die when they are literally swimming in DE. They are still alive after 12 hours but dead at 24 so I don’t believe applying DE on them directly has a very good kill rate.
They drop off the leaves and try to burrow in the ground and I think that rubs off enough of the DE that it makes it a poor option. Certainly less effective than what you will read online about it…
If you are looking for something cheap to dump them into though, it could be a good option. They don’t seem to decompose in it either
The traps built into a rubber trash can have been effective for us. A trash can is a bit overkill for size, but it works.
It helped for me on a small scale. They were eating my echinacea flowers. I put up a trap with lure scent about 30 ft away. They went to the trap instead of the flowers. The infestation was not as extreme as some people are facing.
