Asiatic Garden Beetle

I have a major problem with the Asiatic Garden Beetle in my rose garden. This insect only feeds at night. It is attracted to light, and I was wondering if any of the electronic insect killers would provide control. Does anyone have a problem with these beetles, and how do you control them?

In lawns and other turf areas, the Asiatic Garden Beetle may be controlled as with other white grubs. To manage on ornamentals, use materials such as pyrethrin, rotenone, acephate or carbaryl. Read and follow all label directions carefully.
