Alpine dust is a contact and residual powder insecticide for crack and crevice, spot and void treatment. Alpine Dust has two active ingredients for quicker kill broad-spectrum use: Dinotefuran and Diatomaceous Earth. Dinotefuran is a newer non-repellent active ingredient that the EPA has granted Reduced Risk status for public health use. Dinotefuran is part of the insecticide class neonicotinoids, neuro-active insecticides that are modeled after nicotine. Dinotefuran is a central nervous system inhibitor that takes effect after insects ingest it. Diatomaceous Earth is a completely natural insecticide made of crushed freshwater diatoms (basically tiny algae fossils) directly from the earth. When insects contact or ingest diatomaceous earth, the scratchy surfaces cut through the waxy coating on the insects’ exoskeleton, causing dehydration and eventual death.
Alpine Dust is labeled for carpenter ants and would be an excellent addition to your treatments.
Per the product label: "For ants, apply to ant trails, in openings around doors and windows and other places where ants enter premises. Direct contact with dry dust is required to be effective."
