Quick answer: Adult carpet beetles are tiny (1.5–4 mm), round-to-oval, and mottled black, brown, and white (or solid black/brown). The damaging stage is the larva: a small, fuzzy, bristly, carrot-shaped tan-to-brown creature that looks almost hairy. Larvae feed on natural fibers — wool, silk, fur, feathers, leather — leaving irregular holes in clothing, carpets, and upholstery. They’re one of the most common insects mistaken for bed bugs.
Adults vs. larvae
- Adult carpet beetle: rounded like a tiny ladybug, 1.5–4 mm, often mottled in a black/white/brown pattern. Adults are mostly harmless and are often found near windows (they’re drawn to light and feed on pollen outdoors).
- Larva (the damaging stage): elongated, tan-brown, covered in bristly hairs, sometimes with banded segments — it looks fuzzy. This is what eats your fabrics, hidden in closets, drawers, and along baseboards.
The damage they cause
Larvae chew irregular holes in wool sweaters, rugs, upholstery, and stored clothing, and can damage stored dry goods. Unlike clothes-moth damage (which often comes with webbing), carpet-beetle damage tends to be irregular holes plus shed bristly skins left behind — a key clue.
Carpet beetles vs. bed bugs
People often confuse them. Carpet beetles are rounder, patterned, and found near windows, closets, and stored fabrics, and they don’t bite. Bed bugs are flat, oval, rust-brown, and cluster near the bed. See bugs that look like bed bugs for the full comparison.
Why you have them and how to control them
They enter on cut flowers, secondhand items, or through windows, then larvae settle into dark, undisturbed spots with natural fibers. Control means vacuuming thoroughly (including closet corners and under furniture), laundering or dry-cleaning affected items, sealing stored woolens, and targeted treatment of harborage areas for heavier infestations.

Carpet Beetles — FAQ
What do carpet beetles look like?
Adults are tiny (1.5–4 mm), round, often mottled black/white/brown. Larvae are small, fuzzy, bristly, carrot-shaped, and tan-brown — and they’re the ones that damage fabrics.
Do carpet beetles bite?
No. They don’t bite, but the larval bristles can occasionally irritate skin in sensitive people. The real harm is to natural-fiber items.
Are carpet beetles mistaken for bed bugs?
Yes, very commonly. Carpet beetles are rounder and patterned, don’t bite, and are found near closets and windows rather than the bed.
How do I get rid of carpet beetles?
Vacuum thoroughly, launder or dry-clean affected items, store woolens sealed, and treat harborage areas. Heavier infestations benefit from professional treatment.
