I have had a very bad Japanese beetle year. Without exaggeration, I have had hundreds of thousands of them in my birch trees this year. They have totally obliterated almost every leaf on some of the trees. I have had them in the past in vegetable garden, etc - but never like this. I was reading your article on grubs, etc and it is still unclear to me for the best time to treat. I understand that these beetles have now laid many, many eggs and I would like to both protect my lawn and I would like to prevent another summer of this many japanese beetles. Can you please tell me the best time to treat? Is it to late to treat right now? Will it kill the larvae that has just been laid?
