Help! These pesks have returned! I have chafers eveywhere and could be out all day picking them off. I’ve tried seven granule and spray and they just keep coming! My garden is being destroyed.

I can sympathize with you, as I am currently dealing with the same insect on my property. Sevin in a liquid spray form is one of the most effective materials available without being a certified pesticide applicator, but when the populations are high, you can't kill enough of them quickly enough to keep up with the attack. There is little else you can do. The rose chafers will run their course in about two to three weeks after they first appeared (usually!).
