Taxidermy and natural history
Mounted animals, bird skins, insect collections and feathers are high-risk. Look for fine dust or shed skins beneath specimens and in display cases.
Bare patches in a wool rug or tiny bristly larvae along the skirting? Carpet beetle treatment for carpets, rugs, upholstery and collections, from $89.
Real, verified feedback from people we've helped — straight from Google.
The small round beetles on your windowsill aren't the ones eating your rug. According to the Australian Museum, adult carpet beetles feed on pollen and nectar and spend most of their time outdoors. It's their larvae, hairy little grubs often called “woolly bears”, that feed on wool carpet, rugs, felt, fur, feathers and upholstery indoors.
Larvae hide in dark, undisturbed places close to food: under heavy furniture, along carpet edges and skirting, in lint that collects in vents and cracks, inside upholstery and around old bird nests in the roof. The Australian Museum notes the larval stage can last from about two months to more than a year, so damage builds slowly out of sight.
Our treatment follows the larvae to where they're actually feeding, rather than spraying the room where adults are seen. If the damage is on hanging clothes with silk webbing instead, you're probably dealing with clothes moths, which we treat differently.
Several dermestid beetles cause carpet damage. The larvae differ more than the adults.

Tiny rounded adult with a mottled pattern of white, brown and yellow scales. Larvae are short, fat and densely bristled.

A native species. Larvae are brown with bands of hair, growing to about 5 mm, and feed on wool, fur and feathers.

A larger, shiny dark adult. Its golden-brown larvae are long and tapered with a tuft of hairs at the tail.

A close relative of the varied carpet beetle that works into upholstery padding and the underside of furniture.
Figures from the Australian Museum. The long, variable larval stage is why infestations surprise people.
| Stage | How long | Where it happens | What to look for |
|---|---|---|---|
| Egg | Hatches in about 8–15 days | Laid in dark, protected spots near wool, fur, feathers or lint | Not visible; females lay roughly 40–90 eggs |
| Larva | About 60 days to more than a year | Carpet edges, under furniture, in lint, upholstery and stored textiles | Bristly larvae, holes and bare patches, empty hairy shed skins |
| Pupa | Inside the last larval skin | Near where the larva fed | Split, empty skins left in carpet and cracks |
| Adult | Lives around two weeks | Flies outdoors to flowers, returns to lay eggs | Small round beetles on windowsills and near lights |
Whole life cycle: roughly one to three years, depending on species, temperature and food.

The Australian Museum notes that beetles on windowsills may indicate an infestation inside the home.
Persian and wool rugs, heirloom blankets, taxidermy and felt piano hammers can be damaged beyond repair.
Larvae feed for months under furniture and along edges before a bare patch shows up.
Adults live outdoors on flowers and fly back in, so indoor treatment needs good housekeeping to last.
Find the larvae, remove their food, then treat where they shelter.
We lift rug edges, check under beds and heavy furniture, along skirting, in vents, wardrobes and stored textiles for larvae and shed skins.
The roof void, eaves and wall vents are checked for old bird nests, dead insects and debris that feed larvae.
Affected areas are vacuumed thoroughly, focusing on edges and under furniture, and the vacuum contents bagged and removed.
An APVMA-registered product is applied to carpet edges, under furniture, cracks and skirting where larvae shelter.
You get advice on cleaning or freezing affected rugs and textiles and a vacuuming routine to stop them re-establishing.
| Spot | Why larvae like it | What to do |
|---|---|---|
| Under beds, sofas and heavy furniture | Dark, rarely vacuumed, with hair and lint building up | Move furniture, vacuum thoroughly, treat edges |
| Carpet edges and skirting gaps | Fibres and debris collect where the vacuum doesn't reach | Use a crevice tool; we treat along the edges |
| Under and behind rugs | Wool backing and trapped dust, rarely lifted | Lift and vacuum both sides; freeze or clean small rugs |
| Upholstered furniture | Wool or feather padding, and crumbs down the sides | Vacuum seams and underneath; check padding |
| Heating vents and ducts | Lint, hair and dead insects accumulate | Clean vent covers and reachable duct openings |
| Roof void and wall vents | Old bird and possum nests, feathers and dead insects | Remove nests; consider bird proofing |
| Stored textiles | Blankets, felt, fur and wool left in boxes | Clean, freeze and store in sealed containers |
Where the items at risk can't be replaced, monitoring matters as much as treatment.
Mounted animals, bird skins, insect collections and feathers are high-risk. Look for fine dust or shed skins beneath specimens and in display cases.
Heritage rugs, flags, tapestries and church or school textiles should be inspected on a schedule, including the backs and folds.
Felt hammers and dampers in pianos, and wool or felt parts in other instruments, can be grazed by larvae hidden inside the case.
Sticky insect monitors near vulnerable items help show where activity is starting.
Good housekeeping is the most effective long-term control.
Many Sydney households notice adult carpet beetles in spring and early summer, when they are drawn to flowering plants in the garden and to light at windows. That's a useful prompt: if adults are gathering indoors, there's a good chance larvae are feeding somewhere nearby, often under a bed or in a rug that hasn't been moved in a while.
Homes with wool carpet, Persian rugs, or roof voids where birds or possums have nested are the most common jobs we see. If possums have been living in the roof, possum removal and cleaning up the nest helps remove a source of larvae.

They are small, oval to elongated grubs covered in bristly hairs, usually brown or banded, and a few millimetres long. People often call them woolly bears. Because larvae shed their skin as they grow, finding empty hairy skins along skirting or under rugs is one of the most reliable signs.
Carpet beetles don't bite or sting. Some people report skin irritation from contact with the hairs of the larvae, so it's worth mentioning to a doctor if you have an unexplained rash and larvae in the home. The main issue is damage to wool, fur, feathers and other natural fibres.
Adult carpet beetles are attracted to light and feed on pollen and nectar outdoors, so they gather at windows trying to get out. The Australian Museum notes that finding them on windowsills may indicate an infestation indoors, because larvae may be developing somewhere in the home.
Both eat animal fibres, but they leave different signs. Clothes moth larvae spin silk webbing or carry small cases, and damage is usually on stored or hanging clothing. Carpet beetle larvae are hairy, leave shed skins, and are more often found in carpet edges, rugs and under furniture.
Larvae feed on animal-based fibres, so pure synthetic carpet is far less attractive. However, they can still live in synthetic carpet if hair, lint, pet fur, food crumbs or dead insects collect along the edges, and they can damage wool rugs laid on top of it.
Vacuum thoroughly and often, especially under furniture, along carpet edges and inside wardrobes. Store woollens and blankets clean and sealed. Remove old bird and possum nests from the roof, clear dead insects from light fittings, and fit screens to windows. Indoor treatment alone doesn't stop adults flying back in.
Often, yes. Once larvae are removed and killed, damage stops. Small rugs can be sealed and frozen, and larger ones professionally cleaned. For antique or valuable rugs, consult a specialist rug cleaner or textile conservator about repair. We treat the floor and room so the rug isn't reinfested when it returns.
Yes. Some Anthrenus species are known as museum beetles because their larvae damage taxidermy, insect collections, feathers and wool textiles. Private collectors, galleries, costume stores and churches with woollen textiles should monitor for larvae and treat quickly if they're found.
Treatment starts working once larvae contact treated surfaces, but because the larval stage can last months, you may find the odd larva or adult for a while. Keeping up vacuuming, especially along edges and under furniture, is important. If activity continues after several weeks, contact us to review it.
