Demand Duo Insecticide has a residual up to 90 days to kill those insects that contact a treated area. Per the product label for Carpet Beetles: Apply as a spot or crack-and-crevice treatment to cupboards, shelving, and storage areas. Remove all utensils, uncovered foodstuffs (or any having original package opened), and shelf paper before making application. Allow treated surfaces to dry and cover shelves with clean paper before replacing any utensils, foodstuff, or other items. Any foodstuff accidentally contaminated with treatment solution should be destroyed. Please also review our Carpet Beetle guide for effective elimination.
