Carpet beetle
Anthrenus / Attagenus species
- Identification
- Small, oval beetles (⅛ inch), mottled or solid; the fuzzy larvae are the damaging stage.
- Lifecycle & behavior
- Larvae feed on natural fibers, stored products, and debris; adults are drawn to light and lay eggs indoors.
- When it's active in Central NY
- Year-round indoors; adults often noticed at windows in spring as they seek to move outdoors to lay eggs on flowers.
- Risk & damage
- Larvae damage wool, silk, furs, and stored products, and can be confused with bed bugs or moths.
- Why DIY falls short
- Hidden larval sources (under furniture, in closets, in stored items) make surface treatment incomplete.
- How we treat it
- Locating larval sources, targeted treatment, and guidance on cleaning and storing susceptible items.
Carpet beetle or bed bug?
This is the reverse of the most common bed bug misidentification, and worth getting right in both directions. Adult carpet beetles are small, rounded, and mottled — black, white, brown, or orange patterning depending on species. The larvae, which cause the actual damage and are what people usually find, are elongated and distinctly bristly with visible hairs.
Bed bugs are flat, oval, reddish-brown, and completely hairless. Carpet beetle larvae shed skins that superficially resemble bed bug evidence, which is where the confusion arises. Hair is the deciding feature: bristly means carpet beetle.
Carpet beetles in Central New York
Carpet beetle larvae feed on natural animal fibers — wool, silk, fur, feathers, leather, and felt — as well as accumulated pet hair and lint. They do not touch synthetics. In practice that means damage shows up in stored wool clothing and blankets, wool rugs, taxidermy, felt in piano actions, and undisturbed accumulations under furniture and along baseboard edges.
Older homes with wool carpeting, stored textiles in attics, and long-undisturbed corners are the usual sites, which describes a lot of housing in this region. Damage is often discovered long after it happened, when a stored item is finally unpacked.

Carpet beetle — common questions
Something is eating holes in my wool sweaters. Moths or carpet beetles?
Either is possible, and the evidence differs. Clothes moths leave silk webbing or cases near the damage; carpet beetle larvae leave bristly shed skins and no webbing. Both feed only on natural animal fibers — wool, silk, fur, feathers — and ignore synthetics.
I found small shed skins near my bed. Is it bed bugs?
Check whether they are bristly. Carpet beetle larval skins are hairy; bed bug skins are smooth, flat, and oval. Also look for dark fecal spotting along mattress seams and box spring edges, which indicates bed bugs and which carpet beetles do not produce.
