Why Are There So Many Moths in My House? Moth Pest Control London Answers

If you’ve noticed an alarming number of moths fluttering around your London home, you’re probably asking, “Why are there so many moths in my house?” You’re not alone—moths are a growing headache for homeowners in the capital. From wardrobe-wrecking clothes moths to carpet-chewing culprits, these pests can multiply fast. In this guide, moth pest control London experts at ThermoPest explain why your house is a moth magnet and how to reclaim your space. Let’s uncover the reasons and solutions.

Why Moths Are Drawn to London Homes

Moths aren’t just a UK-wide issue—in London, they’re practically thriving. The city’s humid climate, dense housing, and abundance of natural fibres make it a moth paradise. A piece in The Times reported a surge in moth infestations across Britain, with London’s urban setup—think flats and terraced homes—amplifying the problem.

Adult moths lay eggs, but it’s their larvae that cause the chaos, feeding on wool, silk, and cotton. If your house is full of these materials, you’ve got a moth buffet. Let’s explore why they’re targeting you.

Types of Moths Invading London Houses

In London, clothes moths (Tineola bisselliella) hit wardrobes, while carpet moths (also Tineola bisselliella) target rugs. Case-bearing moths (Tinea pellionella) can strike both clothes and upholstery. ThermoPest’s moth info page online can help you spot the difference. Knowing which moth you’ve got explains why they’re so plentiful.

Reasons There Are So Many Moths in Your House

Wondering why your home is moth central? Here are the top culprits:

Your House Is a Food Haven

Natural Fibres: Clothes moth larvae love wool jumpers and silk shirts, while carpet moth larvae feast on rugs. If your London home is packed with these, moths have plenty to eat.
Unworn Items: Clothes or rugs left untouched for months are prime targets—moths thrive in undisturbed spots.

London’s Climate Helps Them Thrive

Warmth and Humidity: London’s damp, mild weather speeds up moth life cycles, letting eggs hatch and larvae grow faster than in cooler regions.
Indoor Heating: Cosy flats keep moths active year-round, unlike colder UK areas where they slow down in winter.

They’re Sneaking In

Open Windows: Adult moths fly in during warmer months, common in London summers.
Second-Hand Goods: Vintage finds from markets like Portobello can bring eggs into your house.

Neighbours Could Be to Blame

In London’s tight-knit flats or terraces, moths can migrate from nearby homes, multiplying your problem.

Signs of a Moth Takeover

Too many moths? Here’s how to confirm they’re settling in:

Clothes Moth Evidence

Holes in Fabrics: Small holes in wool or silk mean larvae are munching.
Webbing: Silken tubes in wardrobes signal activity.

Carpet Moth Clues

Bald Patches: Worn carpet spots show larvae at work.
Silky Threads: Look under furniture for webbing.

If tiny golden-brown (clothes moths) or beige (carpet moths) adults are fluttering around, they’re laying more eggs.

DIY Fixes to Cut Moth Numbers

Want to fight back? Try these DIY methods for your London home:

Clean and Vacuum

Wash Fabrics: Wash clothes or rugs at high heat (if safe) or dry clean them to kill eggs and larvae.
Vacuum Thoroughly: Hit carpets, wardrobes, and corners, then empty the vacuum outside.

Freeze Treatment

Seal delicate items in a bag and freeze for 48 hours—cold kills moths fast.

Repellents

Lavender, cedar, or rosemary oil can deter adults. Place them around your house, but they won’t stop larvae.

Traps

Pheromone traps catch adult males, slowing breeding. They’re a start, but larvae keep the numbers up

These can trim the moth population, but in London, they often don’t solve the root issue.

Why DIY Won’t Clear Out All the Moths

Moth eggs and larvae hide in carpet fibres, clothing seams, or house cracks. DIY might miss these, letting numbers climb again. In London—where moths can spread between homes—professional help is often the only way to stop the invasion
