Moth treatment for your home

What a professional does

The technician starts by naming the moth. Clothes moths, pantry moths and carpet beetles look similar to a worried householder but leave different evidence, and they are treated in different places. Our identification guide shows how to tell them apart.

For clothes moths the technician treats wardrobes, carpets, skirting boards and edges, where larvae feed on natural fibres. For pantry moths the focus is the kitchen, with the infested food thrown away. Pheromone traps can help the technician monitor how many adults are still flying.

How many visits it takes

Fantastic Services puts most jobs at two to three visits a couple of weeks apart. PestPro Index describes an initial visit and a follow-up four to six weeks later. Either way, the return visit matters, because eggs and pupae survive the first spray.

The life cycle explains why. Eggs hatch in 4 to 10 days, larvae feed for 6 to 12 weeks and pupae last 1 to 4 weeks. A single visit cannot catch every stage.

How long until it is clear

Expect two to three months for clean results, because eggs and pupae outlast the first spray. You will see fewer adults and less damage over that time. Keep using traps to monitor, and keep wardrobes and drawers clean.

Replacing damaged clothes and carpets, deep cleaning and heat treatment are not usually included, and heat treatment is quoted separately. Ask whether the firm gives a guarantee and put it in writing.

What it does and does not fix

Treatment kills the moths and larvae it reaches and cuts the numbers over the following weeks. It does not repair damage or replace what was eaten. It also cannot work if you leave infested clothes or food in place, so the technician will ask you to wash, freeze or throw away anything affected.

Moths often come in on second-hand clothes, rugs, wool throws and stored furniture. Ask the technician where they think the problem started, and check anything recently brought into the house. If you keep heritage textiles, ask about monitoring after treatment.

How to prepare

Before the visit, do what you can to cut the numbers:

• empty wardrobes and drawers so the technician can reach every surface
• wash garments at 60°C where the fabric allows
• freeze items that cannot be washed for 72 hours at -18°C
• vacuum thoroughly, including skirting, corners and under furniture
• throw away infested dry food if you have pantry moths

Our DIY guide covers these steps in detail.

Between visits

Keep the pheromone traps in place and note how many moths each one catches. A falling count shows the treatment is working. Keep vacuuming along skirting boards and under furniture, and leave treated surfaces alone for as long as the technician advises. If you still see larvae or fresh webbing after the last visit, tell the firm and ask what it will do under its guarantee.

When to call a professional

DIY is sensible for a single wardrobe. Call a pest controller for a carpet infestation, for several rooms, for heritage textiles, or when traps keep catching after three months of effort. Moths in heated homes can breed all year, so waiting does not make the problem go away.

A professional also uses products that householders cannot buy, since professional-only insecticides are restricted.

Moths are not just a summer problem

In centrally heated homes, clothes moths can breed continuously all year. You may see more adults when clothes come out of storage, but the larvae have been feeding all along. Moths flying around lights outdoors are usually harmless garden species and nothing to treat.

Renting: who is responsible

Exposure to pests is part of the housing hazard now called "Domestic hygiene" in the Housing Health and Safety Rating System, updated by SI 2026/571. But moth and carpet-beetle damage to a tenant's belongings is rarely a housing hazard.

The tenant usually pays unless the problem comes from the building, such as a nest in a void or a dead-bird infestation. No licence or species protection applies to clothes moths, pantry moths or carpet beetles. The Prevention of Damage by Pests Act 1949 covers rats and mice only.

Choosing a firm

No licence is needed to trade as a pest controller. BPCA and NPTA are trade associations with audits and codes of practice, not licences. Check a firm on the BPCA finder or the NPTA site. BASIS PROMPT and RSPH Level 2 show an individual technician's training.

For museums, collections and heritage textiles, ask about experience with integrated pest management. Before you agree a price, see what moth treatment costs.

Does the council treat moths?

A few councils, such as Lancaster and Test Valley, treat moths and carpet beetles, but most do not. Check yours before you pay a private firm. Our council pest control page shows what yours offers.

Moths eating clothes

Holes in wool, silk, cashmere and fur point to clothes moth larvae. Look for silken webbing, tiny tubes or cases, and golden-buff adults of 6 to 8 mm that avoid light and run rather than fly. The larvae feed on natural fibres for 6 to 12 weeks.

Wash what you can at 60°C, freeze the rest for 72 hours at -18°C, vacuum the wardrobe and use pheromone traps to monitor. If several wardrobes are affected, or the damage keeps spreading, call a pest controller.

Moths in the carpet

Larvae in a carpet are often clothes moths, but carpet beetle larvae cause similar damage. Moth larvae leave silk webbing and tubes. Beetle larvae are 4 to 5 mm and hairy, and leave tiny hairy shed skins and sand-like frass. Check under furniture and along edges, where the pile is undisturbed.

Vacuum thoroughly and often, and empty the bag outside. A severe carpet infestation can cost £300 or more to treat, so call a pest controller early if the damage is spreading.

Moths in the house

Moths indoors are not all the same. A small golden moth that avoids light is a clothes moth. A larger, two-toned moth flying to lights and living near food is a pantry moth. A large dull moth drawn to a lamp is usually a harmless garden visitor.

Identify the moth before you buy anything, because the treatments differ. If you see moths in several rooms, or find damage and webbing, call a pest controller to name the species and treat the right places.

Moths in the cupboard

Moths in a food cupboard are almost always pantry moths: 8 to 10 mm, with two-toned wings, a coppery outer half and a pale grey inner half. Look for webbing and larvae in dried food, such as flour, cereal, rice and pet food.

Throw away infested dry goods, wipe the shelves and vacuum the corners. Store food in sealed containers and do not leave open packets. If the moths keep returning after you clear everything, a pest controller can check the shelf edges and nearby cupboards.

Moths in the kitchen

Kitchen moths are usually pantry moths that have spread from one infested packet. Check every dry food item, including bird seed and pet food, and throw away anything with webbing.

After clearing the cupboards, clean shelves, hinges and corners, and keep food in sealed containers. Pheromone traps show whether adults are still around. Call a pest controller if the moths return after a thorough clear-out, or if you run a food business. Do not use a clothes-moth spray in food cupboards. Throw away infested dry goods instead, and keep the new stock sealed until you are sure the moths have gone.

Moths in the wardrobe

A wardrobe is the classic clothes-moth site: dark, undisturbed and full of natural fibres. A single wardrobe caught early is the case where DIY works well. Empty it, wash or freeze the contents, vacuum every corner and the floor, and add a pheromone trap.

Fantastic Services prices professional treatment for a single wardrobe at £120 to £160. If you find larvae in more than one wardrobe, or in the carpet outside, treat it as a room-wide problem and call a pest controller.
