Finding your favorite wool sweater full of holes or spotting tiny shed skins along the baseboards is never fun — but carpet beetles are one of the most beatable household pests out there. To get rid of carpet beetles, you don’t need to panic, and you usually don’t need an exterminator either. What you need is a thorough, methodical cleanup that targets the larvae doing the actual damage. Here’s the full playbook, step by step.

Signs You Actually Have Carpet Beetles
Most people never see a live carpet beetle doing damage — the adults are small, oval, mottled brown or black beetles that mostly hang around windows, attracted to light. The troublemakers are the larvae: fuzzy, brownish, carrot-shaped little grubs about the size of a grain of rice, often called “woolly bears.” They’re the ones chewing through wool, silk, fur, feathers, and even pet food.
The telltale signs: irregular holes in natural-fiber clothing or upholstery, thin or bare patches on wool rugs, and tiny shed larval skins (they look like miniature translucent husks) tucked along baseboards, under furniture, or in closet corners. You might also find them in stored blankets or in the lint trap area of rarely used rooms. If you’re seeing damage but no insects, check the quiet, undisturbed spots first — that’s their favorite real estate.
Where Carpet Beetles Hide in Your Home
Carpet beetles earned their name, but carpet is only one item on the menu. They love anywhere natural fibers sit undisturbed: under heavy furniture, along the edges of wall-to-wall carpet, inside air ducts, in closets full of wool coats, in boxes of stored linens, and around pet sleeping areas where hair and dander accumulate. Attics and basements with stored textiles are classic breeding grounds.
Don’t forget the kitchen-adjacent spots either — larvae will happily feed on dry pet food, grains, and spices. And here’s one people miss: dead insects in window sills and light fixtures are a food source too. A good first sweep means checking all of these zones, because treating only the obvious spot while a colony thrives under the guest-room bed just resets the clock.
Deep-Cleaning to Get Rid of Carpet Beetles
Vacuuming is your single most powerful weapon here — it physically removes larvae, eggs, shed skins, and the lint and hair they feed on. Vacuum slowly and thoroughly: every carpet edge, under all furniture, along baseboards, inside closets, and under beds. Use the crevice tool where the carpet meets the wall, because that’s prime egg-laying territory.
After vacuuming, immediately empty the vacuum outside into a sealed bag and take it to the outdoor trash — eggs can hatch inside a full vacuum bag and crawl right back out. For rugs, take them outside and beat them, then vacuum both sides. Steam cleaning carpets and upholstery after vacuuming adds heat that kills any eggs and larvae you missed. If a deep-clean weekend is on your calendar anyway, fold this into your seasonal home maintenance routine so it happens on schedule instead of in a panic.
Washing and Heat-Treating Fabrics and Clothes
Anything washable that may have been exposed should go through hot water and a hot dryer cycle — heat is lethal to every life stage, from egg to adult. This includes curtains, throw blankets, pet bedding, stored winter clothes, and cloth storage bins. For items you can’t wash, like wool suits or delicate rugs, dry cleaning works, or you can seal them in a bag and freeze them for at least 72 hours.
While closets are empty, wipe down the shelves and vacuum the closet floor and corners. Consider storing off-season natural-fiber clothing in sealed, airtight containers or vacuum bags going forward — it’s the simplest long-term protection there is. Cedar blocks and lavender sachets smell nice, but treat them as a mild deterrent, not a solution; they won’t save a sweater from determined larvae.
Natural Remedies That Actually Help
Diatomaceous earth (food grade) is the natural option with the most evidence behind it: it’s a fine powder that damages the waxy coating on insects’ bodies, dehydrating them. Lightly dust it into carpet edges, under furniture, and along baseboards, leave it for a few days, then vacuum thoroughly. Wear a mask while applying it — it’s non-toxic but unpleasant to breathe as a dust.
Boric acid powder works similarly and is a staple recommendation from university extension programs. What doesn’t work as a standalone fix: essential oil sprays. They may repel adults briefly, but they won’t touch larvae hidden in carpet padding, and the infestation continues underneath. Cornell’s entomology resources note that physical removal and sanitation remain the foundation of carpet beetle control — sprays and powders are backup, not the main event. For general decluttering that removes their hiding spots, smart home organization pays off here too: fewer undisturbed piles means fewer beetle nurseries.
When to Call a Professional to Get Rid of Carpet Beetles
Most infestations surrender to two or three weeks of diligent cleaning. Call a pest professional if you’re still finding live larvae after a month of thorough treatment, if the infestation spans multiple rooms, or if valuable items are at stake — antique rugs, taxidermy, museum-quality textiles, or a large wardrobe of wool and silk. Pros have access to residual insecticides and the experience to find harborages you’d never think to check, like inside wall voids or HVAC returns.
A good pro will also confirm the identification first. Plenty of “carpet beetle” panics turn out to be clothes moths, which need a slightly different approach, or just normal fabric wear. If you do hire someone, ask exactly what they’ll treat and what prep they need from you — the cleaning prep usually matters more than the spray itself.
Keeping Them From Coming Back
Carpet beetles wander in from outside constantly — adults fly in through open windows and ride in on cut flowers, plants, and secondhand furniture. You can’t seal your home against them entirely, so prevention is about making your house inhospitable. Vacuum under furniture and along edges regularly, not just the visible middle of rooms. Keep window screens in good repair. Inspect secondhand textiles before bringing them inside, and wash or freeze them as a precaution.
Store vulnerable natural fibers in sealed containers, keep pet areas clean, and clear dead insects from windowsills and light fixtures promptly. The EPA’s integrated pest management guidance at epa.gov emphasizes exactly this approach: sanitation and exclusion first, chemicals last.
