(Asiatic Garden Beetles are a new pest in the mid-atlantic and northeast US. They look like a smaller, cinnamon-colored European Chafer, the size and shape of a coffee bean. The grubs do the usual grub thing. The adults are nocturnal and feast on vegetable and flower foliage.)
We're in NH, and are going to lose our basil plants if I don't come up with a way to control these things (adults) within a few days - they are defoliating the plants. I'm thinking to put row cover over the plants, but I want to be sure I'm going to be keeping the beetles out - not in!
