Red flour beetles, Tribolium castaneum, are 1/8 to 3/16 inch long, flattened, and dark cherry to dark brown in color with gradually-clubbed antennae. These long-lived beetles are serious pests of grain processing facilities and food warehouses, but can also be found in grocery stores and home cupboards. Flour beetles cannot eat sound, intact kernels of grain. The grain must be damaged or milled (i.e., flour).
Females may lay up to 1,000 eggs during their life span, which may last several years under ideal conditions. Because adult red flour beetles are very active, can fly, and are sometimes attracted to light, they disperse easily from their initial infestation point. Adult beetles consume food.
