It would be best if you can find the bug(s) so identification is possible. If it is indeed the Japanese beetle, you do NOT want to go out and buy Japanese beetle traps! These use a pheromone to attract the bugs, and you will end up attracting even MORE of them to your yard. Yes, you'll catch many, but why increase the population? Instead, there is a natural insecticide called "milky spore". It is a fungus that attacks the insects!
