Carpet Beetle Identification
How To Identify Carpet Beetles
Adult carpet beetles are small, oval-shaped insects with mottled patterns of black, white, brown, or yellow scales. While adults are mostly harmless and feed on pollen outdoors, their larvae are responsible for damaging household items made from natural fibers.
Carpet beetle larvae are brown, elongated, and covered with tiny bristly hairs. They commonly hide beneath furniture, inside closets, along baseboards, and in stored fabrics where they feed unnoticed.

WHAT CARPET BEETLES NEED
Your Home Provides Everything Carpet Beetles Need.
Carpet beetles thrive where natural fibers, organic debris, and undisturbed storage areas provide food and shelter.
Natural Fibers
Wool, silk, fur, feathers, leather, and other animal-based materials provide ideal food sources for larvae.
Organic Debris
Pet hair, lint, dead insects, and dust accumulate in hidden areas and provide additional nourishment.
Warm Indoor Conditions
Consistent indoor temperatures allow carpet beetles to remain active and complete their life cycle year-round.
Protected Spaces
Closets, storage boxes, attics, basements, and beneath furniture offer safe places to develop.

Carpet Beetle Larvae Cause The Most Damage
