Hi Dave, We have trouble with Japanese beetles. I have a lot of Raspberry bushes and they love the leaves. They also destroyed our new Japanese Maple tree. What we do is have a cup or pail of soapy water, mostly water with a squirt of soap. We take them off by hand. They are clumsy. Just put the cup under the leaf where they are. sometimes they fall in or I just give them a nudge and they fall in. They suffocate in the soapy water after 30 seconds or so. They protect themselves by falling to the ground so put the cup or pail right under where they are. Also, we use a trap called RESCUE Japanese and oriental beetle trap. We have killed thousands this way. You put it about 30ft. away from the plant they are destroying. This trap comes in a two pack. It's the best one we have tried because the pheromone is put on top of the bag. When the bag has a lot of beetles you can open the bottom (its velcro) and empty it in soapy water because they don't all die in the bag but they can't get out. It works really well. Hopefully each year we will have less. I know the soapy water is a task but its worth it. I would do it in the morning and afternoon. It does help along with the bags. Hope this helps. I got them on Amazon. Joann
