Bare patches in wool rugs
Grazed areas along edges and under furniture where larvae feed undisturbed, often down to the backing in a season.

Carpet Beetle Control in Seattle
The beetle on the windowsill is harmless; its larvae are quietly eating your wool, feathers and silk. Varied carpet beetles are among the most common fabric pests in Northwest homes. We trace the infestation to every larval feeding site, treat them directly, and set up the storage practices that keep heirloom textiles safe for good.

In short: Call (206) 944-0849 if you are finding small mottled beetles at windows, bristly larvae along baseboards, shed skins in drawers, or bare patches in wool. We inspect from closets to floor voids to find every feeding site, treat larvae directly where they feed, handle the lint and debris reservoirs that sustain them, and give you the storage protocol that protects wool, silk, feathers and furs permanently.
What this treatment covers
Follow the larvae, not the beetles
Carpet beetle control fails when it chases the adults. The small mottled beetles at your windows in spring are the finished product, feeding on pollen outdoors and laying the next generation indoors; the damage is done entirely by larvae, bristled, carrot-shaped grubs a few millimeters long that feed for months on anything containing keratin: wool carpet and clothing, silk, feathers, down, furs, felt, and the lint, pet hair and dead insects that accumulate in undisturbed corners. The shed skins they leave behind, translucent and intact, are usually the first evidence owners find.
The inspection is a hunt for feeding sites, and there are always more than one: under rarely moved furniture, along carpet edges and in floor vents, in closets and blanket chests, inside upholstery, in the lint of a floor void, around a forgotten bird nest in the attic or an old mouse carcass in a wall. Each site gets treated directly, with applications appropriate to fabrics and living spaces; infested items are triaged honestly between treatment, laundering and heat, and loss; and the reservoirs, the lint and hair deposits that feed larvae between wool meals, are cleaned out as part of the job.
Prevention is where this service earns its keep for households with textiles worth protecting. Sealed storage for off-season wool, periodic disturbance of the quiet zones larvae need, and the attic-and-void checks that catch the nest-based populations before they seed the closets: you get the full protocol in writing.
What the visit includes
- Whole-home larval site inspection: closets, edges, voids, upholstery, attic
- Species confirmation from larvae, skins and adults
- Direct treatment of feeding sites with fabric-appropriate methods
- Reservoir cleanup guidance for lint, hair and debris deposits
- Item triage: what launders, what heat-treats, what is lost
- Written storage protocol for wool, silk, feathers and furs
Catch it early
Six signs the larvae are feeding
Shed larval skins
Translucent bristled casts in drawers, closet corners and under beds are the most common first find, and each marks a feeding zone.
Small mottled beetles at windows
Adults heading for daylight in spring mean a completed generation; count and location hint at how established the cycle is.
Holes in stored sweaters
Scattered holes in off-season wool, often blamed on moths, are as likely carpet beetle work; the skins settle the identification.
Bristly larvae along baseboards
The grubs themselves, slow and fuzzy, commuting along carpet edges or inside floor vents, confirm active feeding now.
A history in the attic
Old bird or wasp nests and rodent remains above the ceiling are classic source populations that reseed the closets below.
The Seattle angle
Wool-sweater country, with the pests to match
Seattle households are unusually good carpet beetle habitat for reasons that sound like compliments. This is a wool city: sweaters, blankets, felted everything, and heirloom textiles, stored through long mild seasons in homes whose closets and floor voids stay at the moderate humidity larvae do well in. The varied carpet beetle, the dominant local species, moves comfortably between outdoor pollen feeding and indoor laying, and the region's mild winters never knock the cycle down the way continental cold does.
The older housing stock contributes its usual share. Decades of accumulated lint in floor voids and heat registers, the occasional historic mouse episode in a wall, and attic corners that have hosted generations of bird nests all function as reservoir populations, which is why our inspections climb past the closet into the attic and voids, and why homes that treat the closet alone see the problem return from above within a year or two.
How the job runs
How a carpet beetle job runs
Call with the evidence
Skins, larvae, damage or beetles; photos help. We will tell you what to leave in place.
Hunt every site
Closets, edges, under-furniture zones, vents, voids, upholstery and attic, until the map is complete.
Treat where they feed
Direct, fabric-appropriate application at each site; no theatrical whole-house fogging.
Clear the reservoirs
Lint, hair and debris deposits cleaned or flagged, and attic nest sources removed.
Protect the textiles
Item triage completed, then the written storage protocol that ends the vulnerability.
Honest numbers
What carpet beetle control costs
Pricing follows the site map. One closet with a single feeding zone is the simple end; a multi-room infestation seeded from an attic nest is the other. What sets your number:
- Count and spread of larval feeding sites across rooms
- Attic or void source populations needing removal
- Upholstery and carpet treatment footage
- Item triage volume where storage has been hit broadly
- Reservoir cleanup scope in vents and floor voids
- A follow-up inspection where heavy infestations warrant verification
Textile damage itself is the cost that dwarfs the service: a single ruined heirloom rug outruns most treatment quotes. The written estimate itemizes sites and scope, and it arrives before anything is treated.
Make the visit count
Before the inspection
- Leave skins and larvae where you found them; locations are the map
- List every item with damage, and set the worst aside unwashed
- Note which closets and rooms store wool, silk, down or furs
- Pull nothing out of deep storage yet; we inspect it in place first
- Flag rooms with rarely moved furniture for under-checking
- Mention any history of birds, wasps or mice in the attic or walls
- Run no foggers beforehand; they scatter larvae into new voids
- Have vacuum access ready, since reservoir cleanup starts same-visit
Straight answers
Carpet beetle questions, answered at the closet door
By the leavings. Carpet beetle larvae shed distinctive bristled translucent skins and graze fabric in irregular bare patches; clothes moth larvae spin silken webbing and cases and feed under them. Bring us either evidence and the identification takes seconds, and it matters, because the treatments differ.
Not meaningfully. They do not bite, though their bristles can irritate sensitive skin on contact, an effect sometimes mistaken for bites. The harm is economic and sentimental: they are efficient destroyers of exactly the textiles people care most about.
Laundering kills larvae and eggs in whatever goes through hot wash or dry cleaning, and aggressive vacuuming is genuinely half the battle, so yes, start there. What home methods miss are the void, vent and attic populations and the sites under furniture nobody moves, which is where reinfestation comes from and where the inspection pays for itself.
Three usual answers: flown in from outdoor pollen feeding through spring windows, carried in on secondhand textiles or dried flowers, or sustained by an indoor reservoir like old nests or lint-filled voids. The inspection names your version, which is what makes the fix durable.
Mostly no; larvae need keratin, so pure synthetics are not food. They will feed on blends, on the wool pad under a synthetic rug, and on the hair and lint that collect in any carpet, which is why synthetic-floored homes still host populations that then find the sweater drawer.
Clean first, since larvae prefer soiled fabric; then sealed, in tubs or garment bags that close completely; then disturbed, meaning the storage gets opened and checked seasonally. Cedar scent is weaker protection than its reputation. The written protocol covers the details per fabric type.
