Un-snug the Bug in Your Rug: Detecting & Preventing Carpet Beetles  

The BPCA report the Carpet Beetle has surpassed the clothes moth as the UK’s number one textile pest. Adult Carpet Beetles feed on pollen and nectar, and do not pose a risk to your clothing and soft furnishings.  However, they lay their eggs in natural, animal-based fabrics. When the larvae hatch, they feed on these fabrics, causing damage.


Carpet Beetles lay white eggs which are smaller than 1mm in length. When hatched, the Carpet Beetle larvae, or “woolly bears” are around 4mm long, and have the appearance of tiny furry caterpillars, with brown bands around their bristly bodies.

There are 3 known species of Carpet Beetle in the UK; The Varied Carpet Beetle, The Furniture Carpet Beetle and the Black Carpet Beetle.

Signs of Infestation

Whilst their name suggests these bugs dwell in carpets alone, the young beetles and larvae are more of a general textile pest. If you have found relatively precise holes in your carpet, upholstery or in your clothes, especially along the fabric seams, it could be that you have a Carpet Beetle infestation. Carpet Beetle larvae feed on natural, animal-based  fabrics as opposed to plant-based cottons, or synthetic man-made fibres, so be sure to check items made of leather, wool, feathers, silk and fur for tell-tale signs of infestation. As Carpet Beetle larvae develop, they shed their skins, which can be the first sign of infestation

When to Spot Them

Adult Carpet Beetles are most often seen between April to June when they are active in search of a place to lay their eggs. The larvae are typically most active in October prior to hibernation.

Life cycle

The lifespan of the Carpet Beetle is around one year.  Over 100 eggs can be laid at a time and take from 10 to 30 days to hatch. The larvae are reasonably resilient and can endure starvation for several months
