It usually starts with one jumper. A couple of small holes, blamed on wear and tear or a snag in the wash. Then it’s the carpet in the spare room, oddly threadbare along the edge where nobody walks. By the time the little golden moths start appearing when the wardrobe door opens, the truth is unavoidable: the house has an infestation, and it has been going on far longer than anyone realised.
Clothes moths and carpet moths have surged across British homes in recent years. Milder winters mean populations no longer die back annually, central heating keeps them breeding year round, and our renewed love of wool and natural fibres keeps them fed. Their larvae, the stage that actually causes the damage, feed unseen for months in carpet edges, under furniture and inside stored clothing, which is why DIY sprays so often fail: they kill the moths you can see while the next generation matures quietly out of reach.
When the supermarket products have failed, or the infestation is clearly beyond one room, professional treatment becomes the sensible move. These are the companies leading the field in the UK right now.
1. Moth Treatment Pros
The unusual thing about Moth Treatment Pros is right there in the name: this is a company that handles moths and nothing else. In an industry where most technicians split their day between rats, wasps and bedbugs, that single focus translates into the kind of detail that decides whether a moth job succeeds. The team identifies the species involved before treating, because clothes moths and carpet moths behave differently, and times its return visits around egg-hatching cycles rather than whenever the diary next allows.
Their specialist moth treatment service covers the full battlefield: carpets and their edges, wardrobes and their contents, stored textiles and the undisturbed corners where infestations restart. It’s an approach particularly suited to households with valuable knitwear or textiles, and to anyone whose infestation has already shrugged off a previous treatment. With moths, half-done jobs reliably come back; full specialisation is the strongest insurance against doing this twice.
2. Thermo Pest
Thermo Pest has staked its reputation on heat treatment, an approach that sidesteps the moth life cycle problem entirely. Rather than spraying and returning to catch the survivors, heat treatment raises affected rooms to temperatures that kill eggs, larvae, pupae and adults simultaneously, ending an infestation in a single chemical-free session. For families wary of insecticides around children and pets, or for severe infestations that need certainty, it’s a compelling method.
Based online at the enviably short pest.co.uk, the firm is strongest in and around London, where its survey-first approach suits the capital’s mix of period properties and flats. Conventional treatments are available where a full heat programme would be more than a light infestation needs.
3. Rentokil
The industry’s biggest name brings what independents cannot: technicians in every corner of the country, decades of protocol refinement and the capacity to treat anything from a terraced house to a hotel floor. Rentokil’s moth service includes conventional residual insecticide programmes alongside heat pod systems for treating infested furniture and clothing.
The scale cuts both ways. Service is more standardised than personal, and pricing sits firmly at the premium end of the market. But for larger properties, commercial premises or areas poorly served by independents, the national machine gets the job done.
4. JG Pest Control
Among independent firms, JG Pest Control has quietly built one of the largest review footprints in the country, and the moth service shows why. Pricing is transparent, coverage spans most of England, and treatments come backed by a written re-treatment guarantee, which matters with a pest as prone to comebacks as the moth.
The protocol pairs residual sprays with clear customer preparation instructions, and the company is honest about when a second visit is needed rather than treating follow-ups as an upsell. Not the cheapest, not the fanciest, but dependable, and with moths, dependable wins.
5. Fantastic Pest Control
Fantastic Pest Control’s pitch is convenience: book online, choose an evening or weekend slot, and in most major cities get a technician out same-day or next-day. For tenants facing an inspection, or working households that can’t burn a weekday on an exterminator visit, that flexibility is the difference between acting now and letting the larvae feed for another fortnight.
The moth treatment itself follows the sound two-visit structure the life cycle demands. As with any franchise network, team quality varies a little by area, so it pays to check local reviews, but the responsiveness is consistently praised.
Before you book: the questions that matter
Whichever provider makes your shortlist, five minutes on the phone reveals a lot.
- Ask how they handle eggs and larvae. Any credible answer involves residual treatment or heat plus a follow-up plan. If the pitch is only about killing moths, keep dialling.
- Ask whether they survey first. Moth infestations are almost always bigger than the visible damage suggests. Companies that inspect before quoting are treating the real problem.
- Ask what you need to do beforehand. Proper firms send preparation instructions: what to wash, what to bag, where to vacuum. This isn’t fussiness; prepared properties get dramatically better results.
- Ask about the guarantee. Reputable companies offer re-treatment terms in writing. Check the duration and what triggers it.
- Ask about method options. Light infestations rarely need the full arsenal; severe ones shouldn’t get the light touch. A provider that offers only one answer regardless of your situation is selling a product, not solving a problem.
The cost of waiting
One last point worth making, because it’s the mistake nearly everyone regrets: moths punish patience. A female clothes moth lays up to two hundred eggs, larvae feed for months, and every generation multiplies the next. The infestation that could have been ended with one treatment in spring becomes a whole-house campaign by autumn, with a bill measured not just in treatment costs but in ruined carpets, coats and heirloom knitwear that no professional can restore.
If the signs are there, holes in wool, grazed carpet edges, little moths in the evening lamplight, get a survey booked. The companies above all offer them, the good ones quote honestly from what they find, and acting a month earlier is invariably the cheapest decision in the whole affair.
