How Do Clothes Moth Get into Your House
How Do Clothes Moths Get Into Your House? (And How to Stop Them for Good)
If you’ve ever opened your wardrobe to find holes in your favourite jumper or noticed small beige moths fluttering near your clothes, you’re not alone. Clothes moth infestations are one of the most common — and frustrating — household pest problems in the UK.
One of the biggest misconceptions is that clothes moths only affect “dirty” homes. In reality, clothes moths prefer clean, undisturbed fabrics, especially natural fibres like wool, silk, cashmere, and fur. This leads many homeowners to ask the same question:
How do clothes moths get into your house in the first place?
In this in-depth guide, we’ll explain every common route clothes moths use to enter homes, why infestations can appear suddenly, and — most importantly — how to stop them permanently. We’ll also link to trusted resources such as MothKill.co.uk and other expert sources so you can take action with confidence.
What Are Clothes Moths?
Before understanding how clothes moths get inside, it helps to know exactly what they are.
The two most common species found in UK homes are:
-
Webbing clothes moth (Tineola bisselliella)
-
Case-bearing clothes moth (Tinea pellionella)
Unlike pantry moths, clothes moths are not attracted to food. Instead, their larvae feed on keratin, a protein found in natural fibres such as:
-
Wool
-
Silk
-
Cashmere
-
Feathers
-
Leather
-
Animal hair (including pet hair)
Adult moths don’t cause damage — it’s the larvae that destroy clothing, carpets, upholstery, and soft furnishings.

How Do Clothes Moths Get Into Your House?
Clothes moths don’t magically appear — they hitchhike, fly, or are unknowingly carried inside. Below are the most common entry points.
1. Through Open Doors and Windows
One of the simplest ways clothes moths get inside is through open doors and windows, especially during warmer months.
Why This Happens
-
Adult clothes moths are weak flyers but can still drift indoors
-
Evening lights attract moths
-
Summer ventilation creates easy access points
While this is not the most common cause of infestations, it does happen — especially in ground-floor flats or homes near gardens, bins, or greenery.
How to Reduce Risk
-
Use insect screens on windows
-
Avoid leaving windows open at night with lights on
-
Install door seals and draft excluders
2. On Infested Clothing and Fabrics (The #1 Cause)
The most common way clothes moths get into homes is via already-infested items.
This includes:
-
New clothes
-
Second-hand clothing
-
Vintage textiles
-
Dry-cleaned garments
-
Stored seasonal items
Why This Is So Common
Moth eggs and larvae are tiny and often invisible to the naked eye. You can easily bring them home without realising.
Even high-street shops, warehouses, and storage facilities can harbour moths.
High-Risk Items
-
Wool coats
-
Knitwear
-
Scarves
-
Blankets
-
Rugs
-
Upholstery covers
This is why experts recommend quarantining new or second-hand clothing before adding it to wardrobes.

3. Second-Hand Furniture, Rugs, and Soft Furnishings
Second-hand furniture is a major but often overlooked source of clothes moth infestations.
Common Culprits
-
Sofas and armchairs
-
Rugs and carpets
-
Cushions and throws
-
Upholstered headboards
Clothes moth larvae can live deep inside padding, seams, and fibres — making them extremely difficult to detect.
What to Do
-
Inspect seams and undersides carefully
-
Vacuum thoroughly before bringing items indoors
-
Consider heat treatment or professional inspection for high-value items
4. From Previous Infestations (Dormant Eggs)
Many homeowners believe moths have “returned” — when in reality, they never fully left.
Why Infestations Reappear
-
Eggs can remain dormant for months
-
Larvae hide deep in carpets, skirting boards, and wardrobes
-
DIY treatments often miss hidden life stages
This is one of the biggest reasons infestations keep coming back.
Professional services like whole-room heat treatment, offered by specialists such as MothKill, are designed to eliminate all life stages in one treatment.
5. On Pets and Pet Bedding
Pets themselves don’t attract clothes moths, but their hair does.
Why Pet Areas Are High Risk
-
Pet hair contains keratin
-
Beds, blankets, and baskets are often undisturbed
-
Warm environments are ideal for larvae
Moths may enter your home on items from groomers, pet shops, or even other homes.
Prevention Tips
-
Wash pet bedding frequently at high temperatures
-
Vacuum areas where pets sleep
-
Keep pet hair under control
6. Through Loft Spaces and Storage Areas
Lofts, basements, and spare rooms are perfect breeding grounds for clothes moths.
Why These Areas Are Attractive
-
Dark
-
Warm
-
Undisturbed
-
Full of stored textiles
Old boxes of clothes, Christmas decorations, or forgotten rugs are common infestation sources.
Regular inspection and proper storage (airtight containers) are key.
7. From Neighbouring Properties (Flats & Terraces)
In flats, maisonettes, or terraced houses, clothes moths can move between properties.
Shared Risk Areas
-
Shared hallways
-
Utility cupboards
-
Adjoining walls
-
Communal storage
If one property has a moth issue, others nearby may soon follow.
Why Clothes Moths Love Your Home
Once inside, clothes moths stay because your home offers:
-
Warmth
-
Darkness
-
Natural fibres
-
Minimal disturbance
They especially love:
-
Wardrobes
-
Under beds
-
Carpet edges
-
Behind furniture
-
Inside drawers
This is why infestations often go unnoticed until damage is severe.
Signs Clothes Moths Are Already Inside
Early detection is critical. Watch for:
-
Small beige or golden moths
-
Holes in clothing
-
Larvae or silken webbing
-
Gritty residue (larval droppings)
-
Bald patches in carpets
If you notice these signs, it’s important to act fast.
How to Stop Clothes Moths Getting Into Your House
1. Regular Cleaning
-
Vacuum weekly
-
Pay attention to edges and corners
-
Empty vacuum outside
2. Wash or Heat-Treat Clothing
-
Wash at 60°C where possible
-
Freeze delicate items
-
Use heat treatment for whole rooms
3. Store Clothes Properly
-
Airtight containers
-
Vacuum-sealed bags
-
Cedar or lavender (deterrents, not cures)
4. Monitor with Pheromone Traps
Traps help detect moth presence but do not solve infestations alone.
When DIY Isn’t Enough
DIY sprays and traps rarely eliminate all life stages.
For established infestations, professional moth heat treatment is widely regarded as the most effective solution.
Heat treatment:
-
Kills eggs, larvae, pupae, and adults
-
Reaches hidden areas
-
Avoids chemicals
-
Delivers fast results
