Both carpet beetle larvae and clothes moth larvae eat natural fibres, but they leave different clues. Knowing which you have changes what you do next.
Small holes in a wool jumper or a patch worn thin in a rug are easily blamed on moths. Often the cause is a carpet beetle instead. Both feed as larvae on natural materials such as wool, fur, feathers and silk, and both prefer places that are dark, undisturbed and a little dusty. The adults of each do very little harm; it is the larvae that matter.
Carpet beetle larvae are small, oval and covered in bristles, and they are often described as hairy or brown and striped. They shed their skins as they grow, leaving behind pale, spiky cases that are easy to spot along skirting boards and in drawers. Clothes moth larvae are pale and smooth, and they live inside silky tubes or webbing that they spin around themselves.
The adults differ as well. Moths are small and buff-coloured and flutter in the dark. Adult carpet beetles are tiny, rounded and often mottled, and they are more likely to be seen on a windowsill in spring, where they have gone looking for daylight.
Sneinton has Victorian terraces with older floorboards, deep skirting and gaps under floors where fluff and debris collect. Those hidden spaces give carpet beetle larvae food and cover for long periods. In a terrace with a bird's nest in the roof, or old wool insulation or felt in the loft space, beetles can build up quietly and move down to carpets and wardrobes. A flat above a shop or market stall storage may bring in different risks, from stored textiles.
Vacuum thoroughly along edges, under furniture and inside wardrobes, and dispose of the bag outside the house. Wash or dry-clean affected fabrics where the label allows. Check loft spaces for old nests or dead insects, which can feed beetle larvae over many months.
If damage keeps coming back, a technician can confirm which insect is responsible and treat the right places. Our free pest prevention survey includes storage advice, and how many visits are needed depends on how far the problem has spread.
A practical test is to look at where the damage sits. Carpet beetle larvae often start at the edges and move out across a room, while clothes moths favour stored, folded items. Placing a few sticky pheromone traps near a wardrobe will catch adult moths and confirm whether they are active, though a trap that stays empty does not rule out beetles.

They are not known for biting or spreading disease. The concern is damage to carpets, clothes and stored items, plus the shed larval skins, which can irritate some people's skin.
Adult carpet beetles are drawn to light and often appear on windowsills in spring. Seeing them suggests larvae may be feeding somewhere nearby, so it is worth checking edges, wardrobes and loft spaces.
