Carpet Beetles in London: Identification and Treatment

Carpet Beetles in London

The Varied Carpet Beetle (Anthrenus verbasci) is one of the most common household pests in London. Like clothes moths, it is the larvae (known as "woolly bears") that cause damage — not the adult beetles.

Identifying Carpet Beetles

Adult beetles: Small (2–4mm), rounded, with a mottled pattern of white, brown, and yellow scales. Often found on windowsills in spring as they seek to fly outside.

Larvae (woolly bears): 4–5mm, covered in brown bristly hairs, found in dark undisturbed areas.

Signs of Infestation

• Damaged wool carpets, particularly in corners and under furniture
• Holes in natural fibre clothing and soft furnishings
• Shed larval skins (brown, bristly husks)
• Adult beetles on windowsills in spring/summer

Difference Between Carpet Beetles and Clothes Moths

| Feature | Carpet Beetle | Clothes Moth | |---------|--------------|--------------| | Adult appearance | Mottled, rounded | Plain golden/buff | | Larvae | Brown, bristly | White, smooth | | Damage pattern | Uniform surface grazing | Irregular holes | | Location | Carpets, bird nests, chimneys | Wardrobes, drawers |

Treatment

Professional insecticide treatment to all affected areas, combined with thorough vacuuming. Bird nests in chimneys and loft spaces are often the source of carpet beetle infestations and must be removed.
