Carpet beetles feed quietly out of sight, so the damage is often found late. These are the signs to watch for and the risks that come with leaving them.
The first clue is often small and easy to dismiss: a few adult beetles on a windowsill, or a bristly brown larva crawling across a floor. Pale cast skins, which look like tiny hollow husks, turn up in drawers, on shelves and along carpet edges. None of these looks dramatic, so they are often left for weeks.
Because the larvae avoid light, damage starts in the quiet places. Look under beds and sofas, along the edges of wool carpets, inside wardrobes and in boxes of stored clothing. Items made of wool, silk, fur and feathers suffer most, but the larvae also eat lint, hair and dead insects, and will move on to other materials once they are established.
Carpet beetles do not bite and are not known to spread disease. The hairs on larvae and the cast skins they leave can irritate the skin or airways in some people, and a rash may be blamed on bites or allergies. If you have recurring itching with no clear cause, it is sensible to speak to a doctor as well as checking for the insects.
In homes the loss is usually clothing, rugs and furnishings, sometimes things of sentimental value. In shops, museums and workplaces holding natural-fibre stock, an unnoticed outbreak can spread to wide areas before anyone sees it. Businesses holding such stock should inspect it regularly.
Natural fibres are the main target. Wool carpets and rugs, silk soft furnishings, feather pillows, fur collars and leather goods can all be eaten, and so can the hair and lint that gather beneath furniture. Synthetic fibres are usually left alone unless they are heavily soiled with food, sweat or body oils, which the larvae are drawn to.
Items put away and not looked at for months are the most exposed. A box of winter clothing or a stored blanket can be damaged in a single season if larvae find it.
Carpets are different, because the damage sits along edges and under furniture where nobody looks. By the time a bare patch is visible, the larvae may have been feeding there for a long while.
Reinfestation usually comes from something left behind. An old nest in the loft, a pile of pet hair under a radiator or a dead insect collection in a void can keep a population going. Treating only the visible damage leaves that reservoir in place.

No, they do not bite. Skin reactions blamed on them usually come from contact with the bristly larvae hairs or cast skins, which can irritate sensitive skin. Persistent unexplained marks are worth checking with a doctor.
Yes. The larvae eat natural materials such as wool, silk, fur, feathers and leather, so clothing, upholstery, stored blankets and similar items are all at risk, as well as lint and hair that collect in corners.
Not necessarily. Carpet beetles arrive from outside as adults, in flowers or through open windows, and from old nests in lofts. Clean homes can be affected. Dust and hair in neglected corners make it easier for larvae to thrive.
