Diet & Feeding

Scavenger that feeds on high-protein organic materials such as dried meats, pet food, cheese, feathers, furs, dead insects, and animal hides.

Behavior Patterns

Adults are nocturnal and attracted to light. Females lay up to 150 eggs near a food source; larvae are active crawlers known for boring into soft wood or insulation to pupate.
