Carpet beetles are tiny pests with a big appetite for natural fibres like wool, silk, and even pet hair. If you’ve noticed mysterious holes in your carpets, clothes, or upholstery, carpet beetles could be to blame.
Don’t worry — they’re common in UK homes, and you can remove them with the right strategy. In this guide, you’ll learn how to get rid of carpet beetles, what causes them, and how to keep them from coming back.
What Are Carpet Beetles?
Carpet beetles are small, oval-shaped insects, typically 2–4 mm long. They come in various colours, from black to mottled brown, and are often mistaken for harmless bugs.
It’s their larvae — not the adults — that cause damage by feeding on natural fibres. They love dark, undisturbed places such as under furniture, behind skirting boards, and in wardrobes.
Signs of Carpet Beetle Infestation
Look out for:
- Small, irregular holes in carpets, blankets, or clothes
- Shed larval skins that look like hairy husks
- Adult beetles crawling on windowsills or near lights
- Itchy rashes (rare, but possible allergic reaction)
What Attracts Carpet Beetles?
They’re drawn to natural materials and areas with limited cleaning or airflow. Common attractants include:
- Wool rugs and carpets
- Pet fur and feathers
- Upholstered furniture
- Dead insects or food crumbs
High humidity also encourages breeding — another reason to consider dehumidifier rental to reduce favourable conditions.

How to Get Rid of Carpet Beetles
1. Vacuum Thoroughly and Repeatedly
Vacuum all carpets, rugs, skirting boards, furniture and cracks in floorboards. Use crevice attachments to reach hidden larvae.
2. Steam Clean Affected Areas
Heat from steam kills eggs and larvae. Focus on soft furnishings and rugs.
3. Wash Fabrics at High Temperatures
Clothing, curtains, or bedding exposed to beetles should be washed at 60°C if the fabric allows.
4. Apply Insecticide or Diatomaceous Earth
Use an insecticidal spray labelled for carpet beetles or apply food-grade diatomaceous earth around edges and under furniture.
5. Seal Entry Points
Inspect windows, door frames and vents. Seal cracks where beetles might enter.
