Behavior and Habitat of Confused Flour Beetles

Female beetles each lay 300 to 400 eggs in flour or other foods during a period of five to eight months. Within 5 to 12 days, these eggs hatch into slender larvae. The larval period varies from 22 to more than 100 days, and pupation takes about 8 days. Adults can live for 3 years or more. The Confused Flour beetle is a scavenger and must rely on other insects to damage grain before it can feed on it. Because of this beetles small size, it frequently invades storage containers. These beetles breed in damaged grain, grain dust, high-moisture wheat kernels, flour, etc. They are prolific and quite damaging.
