Clothes moths can be a silent menace in London homes, nibbling away at your favourite jumpers and scarves without you noticing—until it’s too late. These tiny pests thrive in the capital’s wardrobes, where natural fabrics like wool and silk are plentiful. If you’re a Londoner wondering whether clothes moths have invaded your space, this guide is for you. We’ll break down the key signs to watch for, with expert advice from ThermoPest’s moth control London team. By the end, you’ll know how to spot an infestation and why professional help might be your best defence.

Why Clothes Moths Are a Threat in London
Clothes moths (Tineola bisselliella) aren’t just a random nuisance—they’re drawn to London’s unique environment. The city’s humid climate, combined with its abundance of historic homes and modern flats, creates a haven for these pests. According to the British Pest Control Association (BPCA), clothes moths are a growing problem in urban areas, where wardrobes full of natural fibres provide a feast for their larvae.
Unlike adult moths, which don’t feed, the larvae are the real culprits, chewing through fabrics and leaving behind a trail of damage. If you’ve got woollens, silks, or cashmere stashed away, you’re at risk. Let’s dive into how to spot them and what to do next.
Clothes Moths vs. Other Moths in London
Before we get to the signs, it’s worth distinguishing clothes moths from other species. In London, they’re often mistaken for case-bearing moths (Tinea pellionella), which also target textiles but prefer upholstery and clothing over carpets. Clothes moths, however, are specialists in wardrobe destruction. For more on these pests, ThermoPest’s moth info page offers a detailed breakdown. Knowing your enemy is the first step to effective moth control.
Key Signs of Clothes Moths in Your Home
Clothes moths don’t announce their arrival with fanfare—they’re sneaky. Here’s how to tell if they’ve set up shop in your London home:
Visible Damage to Fabrics
- Holes in Clothing: Small, irregular holes in wool jumpers, silk blouses, or cashmere coats are the most obvious sign. Larvae chew through these materials, leaving behind telltale damage.
- Frayed Edges: Check the cuffs, collars, or hems of garments for fraying caused by feeding.
Larvae and Cocoons
- White Larvae: Tiny, white, worm-like creatures in your wardrobe or drawers are clothes moth larvae. They’re often less than a centimetre long but pack a destructive punch.
- Silken Tubes or Webs: Look for fine, silk-like webbing or small tubes on clothes or in corners—these are protective cocoons spun by larvae.
Adult Moth Sightings
- Small Golden Moths: Adult clothes moths are small (about 6-8mm), golden-brown, and tend to avoid light. If you see them fluttering near your wardrobe or scurrying when you open a drawer, they’re likely laying eggs.
Spotting these signs? ThermoPest’s moth control London experts can assess the situation and offer tailored solutions.
Why Clothes Moths Target Your Wardrobe
Understanding why clothes moths are in your home can help you fight back. Here’s what attracts them:
Natural Fibres Are a Feast
Clothes moths love keratin, a protein found in wool, silk, cashmere, and even feathers. If your wardrobe is full of these materials—especially unworn items stored for months—they’re a prime target.
Dark, Undisturbed Spaces
Wardrobes, drawers, and storage boxes are perfect for clothes moths. They thrive in dark, quiet areas where they can lay eggs undisturbed. London’s compact flats often mean clothes are packed tightly, giving moths plenty of hiding spots.
Second-Hand Risks
Vintage finds from London’s markets or charity shops can bring moth eggs into your home. That preloved coat might look pristine, but it could be harbouring a future infestation.
For more on their habits, the Wikipedia page on clothes moths provides a useful overview. Knowing these triggers can help you spot an infestation early.
DIY Steps to Tackle Clothes Moths
If you’ve caught the problem early, you might try some DIY methods. These can help, but they’re rarely a full solution. Here’s what to do:
Clean and Inspect
- Wash or Dry Clean: Wash affected clothes at a high temperature (if safe) or take them to a dry cleaner to kill eggs and larvae.
- Vacuum Wardrobes: Vacuum shelves, drawers, and corners to remove larvae and webbing, then dispose of the contents outside.
Freeze Treatment
For delicate items that can’t be washed, seal them in a plastic bag and freeze them for 48 hours. The cold eliminates eggs and larvae without damaging the fabric.
Repellents
Lavender sachets, cedar blocks, or rosemary oil can deter adult moths. Place them in wardrobes, though they won’t stop an active infestation.
Traps
Pheromone traps catch adult male moths, reducing breeding. They’re available at hardware stores but won’t tackle larvae already present.
These steps might reduce moth numbers, but in London’s busy households, they often fall short of total control.
Why DIY Isn’t Always Enough
Clothes moth eggs are microscopic and can lurk in seams, folds, or wardrobe cracks. DIY efforts might miss these hidden threats, allowing the infestation to rebound. For a city like London—where moths can spread between flats—half-measures just don’t cut it. That’s where professional moth control comes in.
Professional Moth Control with ThermoPest
When clothes moths take over, ThermoPest’s moth control London experts offer a thorough solution. Here’s how they tackle the problem:
Heat Treatment
Heat treatment kills moths at every life stage—eggs, larvae, and adults—without chemicals. It’s ideal for wardrobes and delicate fabrics, as explained on ThermoPest’s carpet moth treatment page (the method works for clothes moths too!).
Targeted Sprays
Professional-grade insecticides reach deep into infested areas, applied safely by trained technicians who know where moths hide.
Expert Inspections
ThermoPest starts with a detailed inspection to confirm clothes moths (not case-bearing moths or another pest) and assess the damage. This ensures the right treatment for your home.
With ThermoPest, you’re not just chasing moths away—you’re stopping them at the source.
Preventing Clothes Moths in the Future
Once the moths are gone, keep them out with these tips:
Store Smart
- Airtight Containers: Use sealed bags or boxes for woollens and silks, especially during warmer months.
- Regular Checks: Inspect your wardrobe every few months for signs of moths.
Be Cautious with Second-Hand Items
Clean or quarantine vintage purchases before adding them to your wardrobe. A quick wash or freeze can prevent an unwelcome surprise.
Keep It Clean
Vacuum wardrobes and drawers regularly, and avoid letting clothes sit unworn for too long.
Prevention is key, but if moths return, ThermoPest’s ongoing support keeps your home protected.
The Cost of Ignoring Clothes Moths
Clothes moths might seem minor, but their damage adds up. Replacing a ruined cashmere jumper or silk dress in London isn’t cheap, and sentimental items can’t be replaced at all. Acting fast—whether with DIY or professional help—saves you from bigger losses.
