Dusts/Dusters for Beetles as a perimeter treatment for ground beetles . Apply D-Fense dust along and behind baseboards, to window and door frames, corners, pipes, storage locations, attics, crawl spaces and other areas in which these pests may enter or crawl. For carpet beetles, dust where these insects are found. Examples would include on and under edges of floor coverings, around baseboards, under rugs and furniture, and in closets.
