Signs You May Have Carpet Beetles
Many infestations go unnoticed for months because the adults are small and discreet. It’s the larvae that cause the damage.
Common signs include:
-
Small holes in wool carpets, rugs, clothing, upholstery and natural fabrics
-
Brown, hairy larvae (“woolly bears”) in dark undisturbed areas
-
Shed larval skins around skirting boards and under furniture
-
Adult beetles appearing near windows (especially spring and summer)
-
Damage appearing in cupboards, airing cupboards or wardrobes

What are Carpet Beetles?
Carpet beetles are small insects commonly found in UK properties. While adult beetles feed on pollen outdoors, they often enter homes through windows and lay eggs inside.
The larvae are the destructive stage. They feed on:
-
Wool
-
Silk
-
Feathers
-
Hair
-
Leather
-
Natural carpets and rugs
According to the British Pest Control Association, larvae are responsible for almost all fabric damage in homes.

Why MothKill Uses Diesel Heat Instead of Electric Heaters or DIY Methods
Not all heat is equal.
We do not rely on small electric heaters, which are often underpowered and leave cold spots where insects survive.
Instead, we use:
-
Commercial-grade heating systems
-
Controlled airflow systems
-
Professional monitoring equipment
-
Indirect heating (clean heated air delivered indoors)
This ensures the temperature is lethal everywhere, not just “warm in the middle of the room”.

https://www.mothkill.co.uk/preparing-for-insect-heat-treatment/
Typical preparation may include:
-
Decluttering affected areas
-
Vacuuming carpets and edges
-
Making skirting and floor edges accessible
-
Removing heat-sensitive items (we’ll advise)
Aftercare and Prevention
After treatment, we’ll also advise on how to reduce the risk of re-infestation, such as:
-
Deep cleaning of wardrobes and cupboards
-
Regular vacuuming of carpet edges
-
Checking loft spaces if birds have nested
-
Storing vulnerable fabrics correctly
Some councils note that bird nests in lofts and eaves can be a common source of carpet beetles:

Frequently Asked Questions
Does heat treatment kill carpet beetle eggs?
Yes. When applied correctly and monitored properly, professional heat treatment is designed to destroy all life stages, including eggs.
Is heat treatment safe for my home and belongings?
Heat treatment is safe for the building structure and most furnishings. We’ll advise you about any items that may need special handling.
Will I need more than one treatment?
In most cases, a properly delivered heat treatment resolves the infestation in one visit. Severe or widespread infestations may sometimes require further work, and we’ll advise honestly.
Why do carpet beetles keep coming back?
Often the underlying source hasn’t been addressed (such as deep harbourages, loft areas, or ongoing access points). Heat treatment addresses the infestation comprehensively rather than only treating surface insects.
