Carpet Beetle
Anthrenus verbasci
The hairy larvae, known as woolly bears, chew through wool carpets, natural fibre rugs and stored textiles. The adults are harmless: they feed on pollen outdoors and simply fly in through an open window in spring.
Where it lives
Carpet edges under furniture, beneath skirting, in bird nests and roof voids, wardrobes, upholstery and accumulated fluff and hair in undisturbed corners.
Signs
- Small hairy golden-brown larvae in carpet edges and drawers
- Shed larval skins in undisturbed corners and inside wardrobes
- Sharp-edged holes in wool carpet, often along the edge under furniture
- Small mottled beetles on window sills in spring
Risks
- Destroys wool carpets, rugs, upholstery and clothing
- Larval hairs can cause a skin rash in sensitive people
- Damage is often extensive before it is noticed
Prevention
- Vacuum carpet edges, under furniture and inside wardrobes thoroughly
- Remove old bird nests from eaves and roof voids and mesh the access
- Store natural fibre textiles clean and sealed
Treatment
We apply a residual insecticide and growth regulator to carpet edges, skirting voids, under furniture and inside storage, remove and treat any bird nest reservoir in the roof, and re-inspect after two weeks. Removing the source nest is usually the decisive step.
