Auckland humidity feeds it. Your wool carpet is dinner.
Case-bearing and webbing clothes moths thrive in Auckland's coastal humidity, and their larvae eat the keratin in wool carpet, rugs and knitwear. The flying moths are the end of the story, not the start: by the time you see one, larvae have been grazing the quiet zones under furniture for weeks. Treatment is residual spray, steam or both, aimed where the larvae actually live.
Is this your stream?
Threadbare carpet behind and under furniture, holes in stored knitwear, tiny fibre cases or silken webbing in wardrobe corners, small brown moths clustering high on walls. That is clothes moth or carpet beetle larvae, and this stream covers the treatment.
Grey moths around the kitchen and webbing in flour are pantry moths, a different job. Small round holes in floorboards are borer, also a different job. And a single cashmere hole with no other signs may just need a wardrobe clean-out, hot wash and sealed storage, not a spray.
What it costs in Auckland
The published guide band
Pest Control Auckland's carpet beetle guide puts professional fabric pest treatment at $175–$310. It is the only published Auckland band we found; everyone else quotes after inspecting the house.
The national anchor
For a sanity check, Wellington's Combat Pest Control publishes $300 per dwelling for a combined carpet beetle and moth treatment with 6 months or more of protection. Auckland quotes should make sense against that anchor.
The steam option
Steam n Dry combines 84°C truck-mount steam with pest treatment, killing larvae and eggs in the pile on contact. Pricing is by quote and depends on how much carpet and how many wardrobes are involved.

Common mistakes
Fighting the moths you can see: adult clothes moths are weak flyers that scurry into dark corners, and the flying females have already laid their eggs. The creamy-white larvae in the carpet pile do all the damage.
Blaming the wardrobe only: in Auckland's humidity the same moths work wool carpet, rugs and felt as happily as knitwear. Treating one wardrobe while the carpet stays infested just moves the buffet.
Treating only the visible patch: larvae concentrate in undisturbed zones, under furniture, along skirting and inside wardrobes. Professional treatments target those dark crevices, not the middle of the room.
Confusing moth damage with carpet beetle: beetle larvae are hairy woolly bears that shed skins, while case-bearing moth larvae drag a portable fibre case. Both eat keratin and both are treated similarly, but the prep advice differs, so describe what you see when booking.
Storing winter woollens unwashed: larvae are drawn to microscopic traces of sweat, food and skin cells. Sealing dirty knitwear in a bag for summer is laying the table for next season's infestation.
Expecting one visit to end it: the egg-to-adult cycle runs 65 to 90 days and can stretch much further in cool conditions. Traps and follow-up monitoring matter as much as the first spray.
FAQ
How much does carpet moth treatment cost in Auckland?
Pest Control Auckland's guide puts professional fabric pest treatment at $175–$310, the only published Auckland band we found. For context, a Wellington operator publishes $300 per dwelling for a combined carpet beetle and moth treatment with 6 months or more of protection. Everyone else quotes after inspection, and whole-house jobs with wardrobes included will sit above a carpet-only treatment.
Why is Auckland worse for clothes moths than other cities?
Humidity. Auckland's coastal humidity is an ideal incubator for clothes moths, and poorly ventilated rooms sitting around 20 to 25 degrees speed the lifecycle up. The same conditions suit wool carpet in villas and bungalows across the isthmus, which is why treatment here usually pairs spray work with ventilation and monitoring advice.
How do I tell carpet moth from carpet beetle?
Case-bearing clothes moth larvae look like tiny rolled pieces of carpet with a brown head at one end; webbing clothes moth larvae are creamy-white with a dark head and leave silken webbing and pepper-like frass. Carpet beetle larvae are hairy woolly bears that leave shed skins. Adults differ too: small brown moths in upper corners versus small oval patterned beetles near windows and lights.
What does a professional treatment involve?
Expect a residual spray or dust into carpet edges, under furniture, wardrobe crevices and along skirting, sometimes combined with pheromone traps to monitor the adults. Steam n Dry adds 84°C truck-mount steam, which kills larvae and eggs on contact in the carpet pile. Loose rugs and infested clothing may need hot washing, freezing or removal.
Can I treat carpet moth myself?
A small early catch, yes: vacuum thoroughly and often, hot wash or freeze infested clothing and rugs, seal stored woollens clean in airtight bags, and use pheromone traps to monitor. Once bald patches are spreading across rooms, the eggs glued deep in the pile are beyond a household vacuum and a professional residual treatment is the realistic fix.
Budget $175–$310 from the published Auckland guide band, with $300 per dwelling as the national anchor. Pest Control Auckland names clothes moth eradication as a service; Steam n Dry brings 84°C steam for wool carpet; Eco Home Services suits pet households; Tom's names carpet moth treatment outright; Rentokil handles severe whole-house cases. Treat the dark crevices, not the flying moths, and keep pheromone traps out afterwards.
