It measures 3-4 millimetres (less than a quarter of an inch) in length.

The Common Carpet Beetle is common across Europe and the Middle East, in houses or close to houses and buildings.

The larva feeds on keratin and fibres, such as dead insects, animal hair and feathers. The adult beetle feeds on the pollen and nectar of flowering plants. Its predators include the wasp.

Its life cycle is egg, larva (grub), pupa, and adult. The female lays eggs in carpet, textiles, fabric, or in dark, dry places. They hatch into larvae after 14-21 days. The larval form is short and spiky and is often known as woolly bears, like caterpillars. The larva eats for about 60 days, then it pupates. After about 30 days in the pupal stage, an adult beetle emerges. 

The adult beetle is seen from April to August. 

Its life expectancy is about 14 days.
