Wood and fabric

Carpet beetles

Carpet beetle larvae feed on some natural fibres and other materials; shed skins or fabric damage can be clues in homes and stores.

Carpet beetles are small beetles, but it is their larvae that feed on susceptible materials. Depending on the species, larvae can feed on wool, fur, feathers, carpets, upholstery and other stored fabric made from natural fibres. They often feed in dark, undisturbed places, such as wardrobe corners, beneath furniture, along carpet edges or in a store room. Adult beetles may be seen near windows, while the damaging larvae and their shed skins are more likely to be found close to the material they are feeding on.

Feeding can leave holes or worn patches in clothing, rugs and other stored items. Shed larval skins and small debris may help distinguish carpet beetle activity from other fabric pests, though identification is useful before choosing a response. Crepps' proposed IPM approach is to inspect and identify the pest, find affected materials and possible sources, advise on cleaning and storage, then monitor. Targeted treatment would be used only where needed.

Signs

Look for damaged woollen clothing, carpets, rugs, fur, feathers or stored natural-fibre items. Larvae or bristly shed skins may be found in dark, undisturbed places, such as wardrobe corners, beneath furniture or along carpet edges. Carpet beetle larvae do not make the webbing associated with clothes moths.

Why it matters

Carpet beetle larvae can damage natural-fibre clothing, carpets, upholstery and stored items while feeding. Damage may be overlooked in dark or rarely disturbed places. Finding larvae, shed skins and the affected material helps distinguish the source and focus cleaning and control where activity is present.

The IPM approach

Crepps would inspect damaged fabrics and nearby storage, identify the pest and look for larvae, shed skins and likely food sources. The plan would address cleaning and storage, then monitor for further activity. Treatment would be targeted to affected areas and used only where needed.

Prevention

Clean wardrobes, carpet edges and areas beneath furniture regularly, removing lint, hair and other debris. Store clean woollens, fur, feathers and other susceptible items in well-sealed containers. Check stored fabrics periodically and inspect natural-fibre items before placing them away for a long period.
