Carpet Beetle Identification

Carpet beetles are one of the most destructive fabric pests found in homes and businesses across London. Although the adult beetles are harmless and feed mainly on pollen outdoors, their larvae can cause serious damage to carpets, clothing, upholstery, rugs, and other natural materials. Learning how to identify carpet beetles and recognize the early signs of an infestation can help prevent costly damage to your belongings.

Adult carpet beetles are small, oval-shaped insects measuring around 2–4 mm in length. They have distinctive white, brown, and black markings on their backs. The larvae, often called “woolly bears,” are covered with fine hairs and are responsible for most of the damage found indoors.

How to Identify Carpet Beetles

Adult carpet beetles are commonly seen near windows, while their larvae hide in dark, undisturbed areas where they feed on natural fibres.

Characteristics of Carpet Beetles

• Small oval-shaped body
• White, brown, and black mottled pattern
• Approximately 2–4 mm long
• Adults often found near windows or light sources
• Hairy larvae commonly found in carpets and wardrobes

Signs of a Carpet Beetle Infestation

You may have a carpet beetle infestation if you notice:

• Small holes in carpets, rugs, or clothing
• Hairy larvae crawling on fabrics
• Shed larval skins
• Adult beetles near windows
• Damage to wool, silk, leather, feathers, or fur
• Small droppings around infested items

Where Do Carpet Beetles Hide?

Carpet beetles prefer quiet areas where they are unlikely to be disturbed, including:

• Under furniture
• Along skirting boards
• Inside wardrobes
• Loft spaces
• Air vents
• Stored clothing
• Rugs and carpets

Unlike adult beetles, carpet beetle larvae feed on natural fibres and can seriously damage valuable household items. If left untreated, infestations can spread throughout a property, causing extensive damage to carpets, upholstered furniture, curtains, clothing, and stored fabrics.

Early identification and professional treatment are the best ways to protect your belongings.
