Japanese Beetles in Cedar Rapids
I was appalled when I visited my favorite nursery, Culver's in Marion, yesterday, and found Japanese beetles swarming on one variety of shrub, the summersweet clethra. How common are JBs in Iowa? I know my cousin in Illinois has them, but on my rural farm garden I have yet to see them. I pointed out the beetles to one of the employees, and they said yes, they knew they were there and were spraying. They still looked very healthy, however. It makes me very nervous to bring home a shrub from a nursery when there could possibly be JB grubs in the soil. Am I taking this too seriously? Are JBs already common in the Cedar Rapids area, or could these have come in on the nursery stock? I didn't see them on any other plant. If I owned the nursery, I'd isolate and destroy the plant and do everything I could to get rid of them instead of just spraying the area once in a while. I suppose it's inevitable that the little pests will show up eventually, but I'm not going to help them along.
