Discovering moths in your home can cause concern. While moths may seem less intimidating than rats or other pests, they can still cause significant damage – from ruining clothes and textiles to contaminating stored food.
Professional moth control can be expensive, and tackling an infestation yourself might feel daunting at first. But with the right products and some sound advice from our team at PestBuddy, you can deal with moths efficiently and affordably.
If there's one thing we'd want you to take from this guide, it's this: the moths you see fluttering about aren't the ones doing the damage. Adult moths don't feed on fabric at all – it's their larvae that eat through clothes and textiles, hidden away in dark, undisturbed corners. Going after the adults and ignoring the larvae is the single most common mistake we see, and it's the reason infestations keep coming back. Clothes moths are by far the more common problem we're asked about, though the same principle applies to the pantry moths that get into food.
This guide covers how to identify moths, recognise the signs of an infestation, and choose the right DIY products – so you can protect your home and belongings quickly and effectively.
📋 Quick summary: getting rid of moths
- The larvae do the damage – not the adults you see, so swatting flying moths alone won't stop the holes.
- Two pests, two fixes – clothes moths (wardrobes, wool and silk) and pantry moths (kitchen, dried food) need different treatment.
- Clean first – vacuum thoroughly, then hot-wash (above 50°C) or freeze affected items before you trap and treat.
- Pheromone traps monitor, they don't cure – they catch males and show how bad it is, but won't clear an infestation alone.
- Rule out carpet beetles – near-identical holes, different culprit, and moth traps won't touch them.
First, is it moths or carpet beetles?
Occasionally, what people bring to us as a moth problem turns out to be carpet beetles. They cause very similar holes in wool, silk and other natural fibres, but they need different treatment – and, importantly, moth pheromone traps won't catch them – so it's worth a quick check before you buy anything.
The easiest tell is the larvae and the debris they leave behind:
- Clothes moth larvae are pale, smooth and cream-coloured, and often leave fine silk webbing or a small portable case near small, clean-edged holes in dark, undisturbed spots.
- Carpet beetle larvae ("woolly bears") are short, brown and bristly, and leave shed bristly skins and gritty, sand-like frass. The adults are tiny oval beetles, often spotted on windowsills.
If the signs point to beetles, head to our carpet beetle control range instead. Everything else in this guide is for moths.
Types of Moths
There are more than 870 moth species in the UK, though only a handful become household pests. In practical terms there are two groups to worry about: clothes moths, which attack natural fabrics, and pantry (or food) moths, which get into stored food. The size of the moth and the shape of its wings at rest are a good way to start telling them apart. Here are the three you're most likely to meet in a UK home.
Common Clothes Moth (Tineola bisselliella)
Common clothes moths are sometimes known as webbing clothes moths because of the fine silk webbing they leave on clothes. They feed entirely on animal fibres such as wool, fur, silk and leather, all of which contain keratin – fibrous and easy for larvae to digest. Clothes moths are small and beige, with narrow wings fringed with fine hairs, and they prefer dark, quiet areas, so they're seldom seen. That's exactly why they can do a lot of damage to clothing, linen and furnishings before they're noticed. (Its close relative, the case-bearing clothes moth, behaves the same way but its larvae drag a small silk case around with them.)
Adult clothes moths lay 40 to 50 pinhead-sized eggs on suitable fabric, which hatch into hungry, fabric-eating larvae. Depending on species, temperature and food availability, eggs can take anywhere from a month to two years to hatch. Because they reproduce so readily, it pays to learn how to stop moths from eating your clothes.
Indian-meal Moth (Plodia interpunctella)
Indian-meal moths are also known as pantry moths, weevil moths, grain moths or flour moths. They're not native to India but take their name from feeding on Indian meal (cornmeal). The top half of their wings is a light, creamy colour, with brown and bronze towards the bottom. Adults are 8 to 10mm long, and the larvae are creamy-white with a brown head.
They're nocturnal, hiding in dark places during the day. Females lay 60 to 400 eggs, always on food, and the larvae hatch in 2 to 14 days. The larvae spin a silky thread that leaves stringy, clumped bits in food – a sure sign of an infestation. After pupating for 15 to 20 days, they emerge as adult moths. Their larvae can bite through plastic and cardboard, so it's best to store grains in sealed glass containers.
White-shouldered House Moth (Endrosis sarcitrella)
Found in most countries, the white-shouldered house moth is drawn to light and likes to live indoors, often near food sources such as grain stores, kitchens and pantries. It has distinct white shoulders and greyish wings with dark patches. The female lays up to 200 eggs that hatch in one to two weeks. The larvae feed on a wide range of material – grains, cereals, dried fruit, seeds, rotting wood, wool, old textiles and more – so this moth poses a risk to both food and animal-based fabrics in the home.
Moth Behaviour
What is the Moth Lifecycle?
Eggs
Moths begin life in small, pale eggs. Depending on the species, females lay between 40 and 200 at a time, and they hatch in anything from one to 20 weeks depending on temperature and feeding conditions. After a week or two, most hatch into tiny caterpillars, also known as larvae.
Caterpillars (or Larvae)
Caterpillars (larvae) are small, worm-like creatures that come in various colours, including green and creamy white. They sometimes eat their discarded eggs, then begin feeding on the material the eggs were laid on. They shed their skin as they grow, sometimes moulting four or five times in two weeks, until they pupate. This is the stage that does all the damage to your clothes and food.
Pupa
Some caterpillars spin cocoons of silken thread around themselves, while others simply form a hard outer shell. Inside, the change to an adult moth takes place. Within an hour of emerging, the moth's wings have strengthened and it's ready to fly off in search of a mate.
What Do Moths Eat?
Adult moths don't feed at all – they simply lay their eggs near a suitable food source so the larvae can eat once they hatch. Depending on the species, the larvae feed either on animal-based fabrics such as wool and silk, or on grain, dried fruit, cereals, seeds and the like. Some, such as the white-shouldered house moth, will eat both food and fabric.
Identifying Signs of a Moth Infestation
It's the larvae, not the adult moths, that cause the damage – and they're not always easy to spot. Usually you'll notice the damage before the culprits, which means an infestation is already underway. Larvae can be found unhatched or as small caterpillars eating your clothing and food, and they leave behind small silken cocoons that can be shaken out of fabric.
Clothing and Fabrics
Visible Holes in Fabrics
Hold wool, fur and silk garments up to the light and look for small, irregular holes. Check wool and silk carpets for tiny holes too.
Animal-based Materials
Some larvae prefer leather or feathers, so check behind and underneath leather sofas. Give feathered items a good shake outside in the sunlight to see what falls out.
Silken Threads or Webs
Moth larvae spin silken threads to move and feed, often in hidden crevices.
Pupal Casings or Shed Larval Skins
Larvae shed these casings as they grow, leaving them behind as a clear sign of an infestation.
Kitchen and Food
Live or Dead Moths in Your Food
You may spot moths flying out when you open a container, or gathered near the ceiling. You might also find dead moths in the food itself. White-shouldered house moths and Indian-meal larvae give themselves away through the stringy bits they leave behind.
Webbing or Silk
Like clothes moths, pantry moths leave silk webbing in the food they infest.
Pupal Casings
Less common in food than in clothing, but you may still find pupal casings in stored food.
Preventing Moths
Prevention is the best form of moth control. And although moths get talked about as a summer pest, in our experience clothes moth activity stays fairly steady all year – central heating keeps homes warm enough for them to keep breeding through winter – so prevention is a year-round habit, not just a spring clear-out.
If you start seeing small moths flying around, treat it as an early warning rather than the whole problem – the adults you can swat are just the visible sign that larvae may already be feeding nearby. Once inside, moths look for quiet places to hide: under beds, in spare rooms, or in seldom-used cupboards where they won't be disturbed.
Regular Cleaning and Inspections
Cleanliness is key. Vacuum and shake out carpets and curtains regularly, and wash or dry-clean them every so often, particularly anything containing wool or silk. Check vulnerable clothing such as woollen jumpers, coats and scarves, and clean clothing and linen cupboards thoroughly. A good time to do this is when the seasons change and you swap summer and winter clothes – remove everything, wash the shelves with a vinegar-and-water solution, getting into cracks and corners where eggs may be hiding, and let them dry before replacing the clothes. Always wash clothes before packing them away for a season.
If that feels like a big job, tackle a few shelves at a time – but if you suspect an infestation, it's better to do the whole cupboard, and perhaps the whole home. You can store woollens in breathable but mothproof plastic or fine-mesh covers, and give them a good shake-out when the season turns again.
Use Airtight Containers
Store all food – grains, pulses and spices – in airtight containers. Glass or hard plastic jars are best, as larvae can eat through bags and cardboard. Before using food, check for small insects or stringy bits stuck to the sides or top of the container. Don't leave food out overnight, and keep countertops, shelves and floors clean.
Store Clothes Properly
Keep closets and drawers organised and cleaned regularly – clutter and undisturbed corners are exactly where moths set up home.
Natural DIY Moth Control
It's always preferable to tackle a pest with natural methods before reaching for chemicals. Natural products are kinder to your health and the environment, and they work well as part of a wider plan.
Cedarwood, Lavender and Other Herbs
Moths dislike certain scents, particularly cedarwood and lavender, and the good news is these are inexpensive and leave your home smelling pleasant. Scented coat hangers, sachets, oils and sprays can all be used safely in clothing and linen cupboards. Before storing clothes for the season, fold a few sprigs of dried lavender into woollens, or fill small muslin bags with strong-smelling herbs such as rosemary, thyme, cinnamon and cloves, and place them in cupboards. Lavender-scented linen sprays can be used on curtains and carpets, and natural repellent sprays are available for the kitchen too – just check the ingredients before you buy.
Vacuum and Clean Regularly
Moths are drawn to soiled areas where body oils, food stains and sweat linger. Regular cleaning and vacuuming makes those areas far less attractive – and removes eggs and larvae in the process.
Launder or Freeze Infested Items
Wash affected items in hot water (above 50°C) or have them dry-cleaned. Alternatively, seal items in a plastic bag and freeze them for two to three weeks – freezing kills eggs, larvae and adults, and is unlikely to harm the garment.
Moth Traps
The moth traps you'll use at home aren't the light traps researchers use – they're pheromone traps. Each one is baited with the scent given off by female moths, which draws in the males and holds them on a sticky surface. They're non-toxic and safe to use around children and pets, which makes them the natural first step before any spray.
Because they only catch males, their real strength is as a monitoring tool: they confirm you have moths, show which type, and tell you how bad the problem is – rather than clearing an infestation on their own, since females carry on laying. Use the right trap for the moth: place clothes moth traps in wardrobes and drawers, and pantry moth traps in food cupboards. A sudden, heavy catch is your signal the problem is bigger than it looks and it's time to step up cleaning and treatment.
Moth Decoys
A longer-term option for clothes moths is a moth decoy – carnauba wax micro-powder loaded with female moth pheromones. The powder attracts male moths and clings to their antennae; now coated in female pheromones, the confused males stop mating. Over time this reduces the number of eggs laid and the likelihood of future generations setting up home in your cupboards.
If you'd rather start with everything in one place, our Starter DIY Clothes Moth Control Kit pairs non-toxic traps with the essentials for getting on top of a clothes moth problem.
Chemical Solutions for Moth Control
There are many chemical moth-control products on the market, including sprays, powders and paper strips. We recommend trying non-toxic options first, and only moving to chemicals where they're genuinely needed. Whatever you choose, read the label, understand the ingredients, and follow the instructions carefully.
Insecticides
Moth insecticide sprays can help control visible moths, especially as a fast-knockdown treatment. Where suitable, many customers prefer to start with pesticide-free insect sprays, but these are best for spot-treating adult moths you can see and may not address the full infestation on their own.
For larger or recurring problems, longer-lasting treatments tend to be more effective. Residual insecticide sprays can be applied to suitable harbourages and resting areas; once dry, they leave an active deposit that keeps working as moths and larvae contact treated surfaces later. Insect growth regulators (IGRs) can also help as part of a wider plan, targeting developing stages in the life cycle to reduce future breeding and re-infestation.
For best results, combine insecticides with thorough cleaning, vacuuming, laundering, decluttering and pheromone traps for monitoring.
⚠️ Using moth sprays safely
Always read and follow the product label – it's a legal instruction, not a guideline. Ventilate the room, keep children and pets away until treated surfaces are dry, and never spray near food or open packaging. Don't spray garments, bedding or delicate fabrics directly unless the label specifically allows it, and spot-test first. Target cracks, crevices, carpet edges, skirting and wardrobe interiors where larvae develop, rather than spraying into the open air.
A word on mothballs
The mothballs most people picture – the strong-smelling white ones – are banned in the UK. Both traditional actives, naphthalene and paradichlorobenzene, were withdrawn over health risks, so the classic mothball is no longer legal to sell here. Cheap mothballs still appear on online marketplaces, and many are seized because they still contain banned naphthalene, so they're best avoided entirely.
Some modern products in mothball form use an approved pyrethroid instead (such as transfluthrin or permethrin) and are legal. But they're meant for use only inside a sealed container, the vapour isn't something you want around children or pets in an open room, and the label has to be followed closely. If you'd rather skip that, the pheromone traps, cedar and lavender, and targeted moth sprays covered here are what we'd point you to.
Cleaning and Repairing After a Moth Infestation
Once the moths are gone, clean up the aftermath – it's what prevents a re-infestation.
Deep Clean Spaces
A thorough clean removes any eggs or larvae left behind. Vacuum carefully, paying attention to edges, corners and undisturbed areas, and empty the vacuum outside afterwards.
Repair Damaged Items
Partially eaten items can be repaired or, where the damage is too great, replaced.
Launder or Dry Clean Affected Items
Anything that may have been exposed needs a thorough wash or dry clean to make sure no eggs or larvae remain.
When to Use Professional Pest Control for Moths
If you've worked through the steps above and moths keep coming back, it may be time to call in a professional. The clearest signs are: activity that spreads across more than one room, an infestation that returns after a full clean-and-treat cycle, difficulty identifying the moth (and therefore choosing the right product), or vulnerable people in the home who'd be better kept away from treatments.
A professional can identify the species, find the larval source, and advise on follow-up treatments if needed.
FAQs: getting rid of moths
Why do I suddenly have moths in my house?
Most moth problems are brought in rather than flown in – usually on second-hand or stored textiles, rugs and furniture, or in dried food from the cupboard. Clothes moths can then breed indoors all year, because central heating keeps homes warm enough through winter.
Are clothes moths and pantry moths the same thing?
No – they're different species with different tastes, so the treatment differs. Clothes moths eat natural fabrics like wool and silk in wardrobes, while pantry moths get into dried food in the kitchen, so match the trap and the approach to the right one.
What kills moth larvae and eggs?
Heat and cold both do it: a hot wash above 50°C, or sealing items in a bag and freezing them for two to three weeks, kills eggs, larvae and adults. Thorough vacuuming clears them from carpets and crevices, and residual or IGR sprays target stages hidden in cracks.
Do moth pheromone traps actually work?
They work well for monitoring, but not as a standalone cure. They catch male moths and tell you what you're dealing with and how bad it is, but females keep laying – so pair them with cleaning, laundering and, where needed, targeted treatment.
Does lavender or cedar actually repel moths?
They help deter moths, but they don't kill larvae or eggs, so treat them as one layer rather than a fix on their own. Refresh the scent regularly – lightly sand cedar and top up lavender – as it fades over time.
How long does it take to get rid of moths?
Usually a few weeks to a couple of months, depending on how established the infestation is. You can be confident it's over when you see no new damage and your traps stop catching over several consecutive weeks.
Final Thoughts
By following the strategies in this guide, you can keep a moth-free home and protect both your peace of mind and your belongings. Quick identification and prompt action are key – and remember that it's the larvae, not the adults, you're really targeting.
Sealing potential entry points builds a strong defence, and a clean, clutter-free home with no exposed food gives moths little reason to stay. Traps and natural repellents let you deal with problems early, before moths can breed unchecked – and if the situation becomes overwhelming, professional help is always an option.
By making these habits part of your routine, you keep moths from taking hold and protect your home and belongings for the long term.
