How to Deal with a Clothes Moth Infestation
How to Deal with a Clothes Moth Infestation (Complete Guide)
A clothes moth infestation can be deeply frustrating, costly, and surprisingly emotional—especially when favourite garments, heirlooms, or expensive wool items are damaged. Unfortunately, clothes moths are one of the most common household pests in the UK, and they often go unnoticed until significant harm has already been done.
The good news? Clothes moth infestations can be fully eliminated with the right approach.
In this comprehensive guide, we’ll walk you through everything you need to know—from identifying clothes moths and understanding why they infest homes, to proven treatment methods and long-term prevention strategies. We’ll also explain when DIY methods fall short and why professional clothes moth control, like the expert services provided by Mothkill, delivers permanent results.
What Are Clothes Moths?
Despite the name, clothes moths don’t actually eat clothes. Instead, it’s the larvae that cause the damage by feeding on natural fibres.
The two main species responsible for infestations in the UK are:
• Common Clothes Moth (Tineola bisselliella)
• Case-Bearing Clothes Moth (Tinea pellionella)
Both prefer natural fibres such as:
-
Wool
-
Cashmere
-
Silk
-
Fur
-
Feathers
-
Felt
They avoid synthetic fabrics like polyester or nylon unless blended with natural materials.

How to Identify a Clothes Moth Infestation
One of the biggest challenges with clothes moths is that you rarely see the adults, and by the time you notice damage, the infestation is already established.
Common Signs of Clothes Moths
Small holes or thinning patches in clothing Silk webbing or larvae casings inside garments Adult moths fluttering near wardrobes or cupboards Damage concentrated in dark, undisturbed areas Gritty debris at the bottom of wardrobes
Adult clothes moths are small (around 6–8 mm), golden-beige in colour, and weak fliers. They prefer darkness and often scatter when disturbed.
Why Clothes Moths Invade Homes
Contrary to popular belief, clothes moth infestations have nothing to do with poor hygiene. Even the cleanest homes can be affected.
Clothes moths are attracted to:
• Dark, quiet storage spaces
• Natural fibres
• Perspiration, skin oils, and food stains
• Seasonal clothing left untouched
• Low-level humidity
Urban homes, period properties, flats with limited ventilation, and homes with large wardrobes are particularly vulnerable.
Understanding the Clothes Moth Life Cycle (Why DIY Often Fails)
To effectively deal with clothes moths, you must understand their life cycle.
The Life Cycle
-
Eggs – laid deep within fabric fibres
-
Larvae – the damaging stage (feeds for months)
-
Pupae – cocoon phase
-
Adult moths – reproduce but don’t cause damage
Eggs and larvae are extremely resilient and often survive:
Sprays Moth balls Trap-only methods
This is why many infestations persist for months or years when treated incorrectly.

Step-by-Step: How to Deal with a Clothes Moth Infestation
Step 1: Identify the Scope of the Infestation
Start by checking:
-
Wardrobes
-
Drawers
-
Cupboards
-
Under beds
-
Rugs and carpets
-
Upholstered furniture
Pay special attention to items rarely moved or worn.
Step 2: Isolate Affected Items Immediately
Remove all suspected clothing and seal items in plastic bags to prevent larvae spreading. Do not shake garments indoors—this disperses eggs and larvae.
Step 3: Treat Clothing Correctly
Effective methods include:
Washing at 60°C (if fabric allows) Dry cleaning Freezing garments at -18°C for at least 72 hours Heat treatment above 50°C
Freezing is especially useful for delicate garments like cashmere or silk.

Step 4: Deep Clean Storage Areas
Vacuum thoroughly:
-
Wardrobe joints
-
Corners
-
Cracks and crevices
Immediately dispose of the vacuum bag outside the property.
Wipe surfaces with mild detergent—avoid relying solely on insect sprays.
Step 5: Avoid Common DIY Mistakes
Many people unknowingly make the problem worse by:
Using moth balls (toxic, outdated, and ineffective) Relying on pheromone traps alone Using supermarket sprays that only kill adults Treating only visible areas
Pheromone traps are monitoring tools, not a cure.
When DIY Isn’t Enough (And Why Professional Treatment Works)
If moths keep returning, larvae are hidden deep within fibres or inaccessible areas. At this stage, professional clothes moth treatment is the only reliable solution.
Why Professional Treatment Is Different
Targets eggs, larvae, and adults Treats entire infested zones Uses industry-grade products safely Eliminates source, not just symptoms
