Exactly what "Asian Beetles" are you talking about? Asian Beetles usually refers to Asian Lady Bug beetles - small multi-colored spotted beetles that look like ladybugs except for the color - which don't do any damage in the garden and consume aphids so are considered a beneficial. But they are an indoor winter pest problem.

Or are you talking about Japanese Beetles - large, dark brown and metallic green, shiny exoskeleton beetles that derive from grubs in the ground and make a loud clicking noise as they fly. They do do garden damage. Several discussions here about them.

Thanks for the email clarifying that it is Japanese Beetles you were talking about.
