Moth control and extermination
When moths keep coming back after cleaning, washing and traps, a professional treats the places the larvae live: carpet edges, under furniture, wardrobes and the gaps behind skirting. Most homes get an insecticide course of two to four visits, typically £120 to £240 for one room and up to about £450 for a whole home outside London. Heat is an option for a one-visit treatment with no insecticide on the heated items, at a higher price.

Signs it is time for a professional
- You still see small, pale moths indoors weeks after cleaning and vacuuming.
- New holes keep appearing in wool jumpers, suits, scarves or blankets.
- Carpets or rugs have thin or bare patches, often at the edges or under furniture.
- You have found larvae, silky webbing or small cases in drawers, wardrobes or carpets.
- Pheromone traps are catching moths week after week.
- You let the property, run a business, or own textiles you cannot afford to lose.

What a good quote includes
Ask for these six points in writing. Two quotes that cover them can be compared line by line.
A survey first
Which moth it is, where the larvae are and how far they have spread. Treating only where you saw adults rarely works.
The method, named
Spray, fog, heat or a mix, with the product used and why it suits your home, children and pets.
Rooms and items covered
Each room and each piece of furniture or rug included, so nothing affected is left out.
Number of visits
How many visits the price includes and how far apart, so the eggs that hatch later are caught too.
Your part
What you need to wash, bag, freeze or move before each visit, and how long to stay out afterwards.
If moths come back
What a further visit costs, and whether any guarantee is offered and on what terms.

Survey
The technician identifies the moth, finds where the larvae are feeding, and explains the method, visits and price.
Preparation
You vacuum thoroughly, wash or bag clothes and textiles, clear wardrobe floors and move furniture away from the walls.
Treatment
Carpets, edges, cracks and wardrobes are sprayed or the rooms are heated. With a spray you usually stay out for a few hours.
Follow-up
With insecticide, one to three more visits a few weeks apart deal with larvae that hatch from eggs left behind.
Questions people ask
What does a moth exterminator do?
They find out which moth you have and where its larvae are feeding, then treat those places, usually with a residual insecticide spray or fog, sometimes with heat. A course of visits catches larvae hatching from eggs that a first visit cannot reach.
How many treatments does it take to get rid of moths?
Council services in London typically book two visits about two weeks apart; private courses run to three or four. Heat treatment is usually one visit. Ask what an extra visit costs, usually £60 to £130.
Can I get rid of moths myself?
Light problems often respond to thorough cleaning. The British Pest Control Association suggests washing items before storing them, using airtight storage, vacuuming carpets and the cracks behind radiators, and freezing items at -18°C for two weeks. If damage keeps appearing, it advises calling a BPCA member.
Do pheromone traps get rid of moths?
Not on their own. English Heritage says the traps attract only males and will not control an infestation. They are useful for finding where moths are and checking whether a treatment has worked.
Is the treatment safe for children and pets?
Professional insecticides are applied under strict rules, and you are normally asked to keep people and pets out until surfaces are dry. Council services in London advise leaving the home and coming back at least three hours later. Tell the firm about fish tanks, babies, pregnancy or breathing problems before they start. Heat treatment uses no insecticide on the heated items.
Will my home insurance pay for moth damage?
Usually not. MoneySuperMarket says most standard home insurance policies will not cover it, and policy wording often excludes damage caused by moths and insects outright. Check your own policy.
