times I can spray them without damaging the plants? I am in Chicago,

Hi. Just joined this forum, so you may have found a solution already to your problem. I'm in the west of England and had the same problem with Japanese beetles last summer (also called Garden Chafers here). There is a new product, a nematode, which you water into the ground surrounding the rose/s in September. The nematode attacks the beetle lavae, so they don't hatch next year. I buy these on the net from a uk website, but, of course, they can't be exported to US as they're live! See if you can find them on a US website. Good luck! diana
