Properly ventilate the storage area to discourage these moisture-loving pests. Heat-treat dried fruits or vegetables by placing in a cheesecloth bag, and dipping in boiling water for 6 to 10 seconds. Sifting the food material will remove possible insect fragments, and any remaining fragments will not cause harm if consumed. After insects are killed, contaminated food might be used outdoors during the winter months for bird feed. Seeds saved for planting may have the germination reduced by super-heating or cooling.
Careful sanitation is the best method to avoid stored-product pests.
After removing all food, food packages, utensils, dishes, etc. Scrub with soap and hot water. After shelves are thoroughly dry, cover with clean, fresh paper or foil before replacing with food or cooking utensils. The ability of these insects to find a small amount of food is amazing. The use of insecticides is discouraged around food materials.
