Natural Habitat

Indoor environments such as homes and warehouses, as well as outdoor nests of birds, rodents, or insects.

Diet & Feeding

Scavengers that consume animal-based products including wool, silk, leather, fur, feathers, and dried protein materials like pet food or dead insects.

Behavior Patterns

Larvae are avoidant of light and prefer dark, secluded areas where they feed and grow. Adults are often seen on windowsills as they are attracted to light and seek to move outdoors to feed on pollen.

Risks & Benefits

They are serious household pests that can damage clothing, carpets, and upholstery. While they do not bite humans, the hairs on the larvae can cause skin irritation or allergic reactions in sensitive individuals.
