Somewhere in Britain right now, someone is holding a cashmere jumper up to the light and swearing. Clothes moths have become one of the country’s fastest-growing household headaches, with infestation callouts rising year after year. Warm homes, mild winters and our collective return to natural fibres have created ideal conditions, and the insects have taken full advantage.
The cruel joke is that moths have expensive taste. Their larvae feed on keratin, the protein found in wool, cashmere, silk and fur, which means the fast-fashion polyester survives untouched while the investment pieces get devoured. Worse, the larvae do their feeding in secret, working through carpet edges, under sofas and inside stored clothes for months before the first adult moth ever flutters into view. By then, a full breeding population is established, which is why the spray from the supermarket so rarely ends the story.
When it’s time to bring in professionals, these are the five services leading the UK market, ranked on method, expertise, guarantees and reputation.
1. Moth Treatment Pros
Specialisation is rare in pest control, where most firms handle everything from rats to wasps, and that’s exactly what makes Moth Treatment Pros stand out: the company does moths, full stop. The benefits of that focus run through the whole service. Treatment starts with proper species identification, since clothes moths and carpet moths demand different plans. Insecticide programmes cover not just the obvious carpet but the wardrobe interiors, stored textiles and skirting margins where reinfestations begin. And follow-up visits are scheduled around the moth breeding cycle, catching the larvae that hatch from any eggs the first pass missed.
It’s the right call for households protecting valuable knitwear or textiles, and the obvious next step for anyone whose infestation has already beaten a previous treatment. Moth jobs fail on detail, and detail is the entire business model here.
2. Thermo Pest
Where most treatments fight the moth life cycle visit by visit, Thermo Pest simply switches it off. The company’s speciality is heat treatment: infested rooms are gradually raised to temperatures that no moth egg, larva, pupa or adult can survive, ending the infestation in one chemical-free session. For families who’d rather not have insecticides applied around children, pets or bedding, or for severe infestations where a guaranteed reset matters more than anything, it’s the most decisive tool in the industry.
Fittingly for a company that managed to secure pest.co.uk as its web address, the operation is slick: surveys before quotes, treatment plans matched to the actual spread of the problem, and conventional residual options for lighter cases that don’t need the full furnace. Strongest in London and the surrounding counties, where the capital’s period homes and packed flats keep moth pressure high.
3. JG Pest Control
JG Pest Control has become one of England’s most reviewed independent pest firms by doing unglamorous things well: transparent pricing, wide coverage, straightforward advice and a written re-treatment guarantee behind every moth job. The treatment protocol pairs residual insecticide application with detailed preparation instructions, and the company is refreshingly honest about when a second visit is genuinely needed.
There’s no single-pest specialism or heat-treatment theatre here, just reliable professional work at fair prices with a safety net in writing. For straightforward infestations, that combination is exactly what most households want.
4. Rentokil
The biggest brand in the business brings unmatched geography: wherever you live, Rentokil has a technician within range. Its moth service spans conventional insecticide treatment and heat pod systems for infested items, all delivered through protocols refined over decades and at a scale that suits large homes, hotels and commercial stockrooms as comfortably as flats.
You pay for the badge, with pricing at the premium end and a service that’s more process than personal touch. But for multi-site businesses, or customers in regions where independents are thin on the ground, the national reach settles the argument.
5. Fantastic Pest Control
Fantastic Pest Control’s contribution to the industry is making it bookable like a taxi. Online scheduling, evening and weekend slots, and same-day availability across most major cities mean the gap between discovering moths and treating them can be measured in hours rather than weeks. The moth service itself is properly structured, with an initial treatment and a timed second visit to intercept newly hatched larvae.
Franchise operations always carry some variability between local teams, so check reviews for your area. But when speed matters, for tenants ahead of an inspection or anyone whose skin crawls at the thought of waiting a fortnight, the booking convenience is the winning feature.
The questions that separate good from lucky
However you shortlist, a quick interrogation before booking pays for itself.
How does the treatment deal with eggs and larvae? The only answers worth hearing involve residual products, heat or both, plus a follow-up plan. Killing visible moths is cosmetic.
Is there a survey first? Infestations are invariably bigger than the damage you’ve found. No inspection means the quote is a guess.
What preparation is expected? Detailed instructions on washing, bagging and vacuuming are a mark of a company that intends to succeed. Silence on prep is a warning.
What does the guarantee say, in writing? Duration, conditions, what triggers a free re-treatment. The good firms volunteer this; the rest hope you won’t ask.
Does the recommendation fit the problem? A light single-room infestation doesn’t need the nuclear option, and a whole-house problem won’t yield to one quick spray. Beware the one-size answer.
Don’t feed them another season
The maths of moth infestations only moves in one direction. Each female lays up to two hundred eggs, each generation feeds for months, and every week of hesitation converts directly into eaten carpet and ruined knitwear that no treatment can bring back. What starts as two holes in a jumper becomes, given a season of benefit-of-the-doubt, a bill running into the thousands.
The companies above all offer surveys, most within days. Book one at the first signs, prepare the house properly, insist on the follow-up visit, and the whole episode ends the way it should: quickly, thoroughly and once.
