Diet & Feeding

Polyphagous; they consume a wide variety of dried plant products including flour, bread, spices (like paprika and chili powder), seeds, and prescription drugs.

Behavior Patterns

Adults are capable of flight and are attracted to light. Females lay eggs on food sources; larvae burrow into the food to feed and pupate. They have a symbiotic relationship with yeast that aids in digestion.

They are a significant indoor pest that can contaminate and ruin stored food products. While they do not bite or transmit diseases to humans, infested food should be discarded as it can be tainted with fecal matter and cocoons.
