FAQ
Frequently Asked Questions
No. They are different species. Clothes moths (e.g., Tineola bisselliella) feed on wool, fur, and other keratin-based materials. Flour moths feed on dry plant-based foodstuffs like flour, cereal, and nuts.
It is strongly discouraged. The food is contaminated with larvae, webbing, frass (droppings), and shed skins, which can cause allergic reactions or spoil the taste. Discard infested food.
They rarely do. Usually, the eggs or larvae were already present in the food when it was packaged at the factory or store. They can also chew through thin plastic or cardboard or enter through tiny gaps.
Find and dispose of all infested food. Thoroughly clean cupboards with vacuum and soapy water. Store new dry goods in glass, metal, or thick plastic containers. Consider using pheromone traps to catch adult males and monitor the situation.
