About Beetles

There are two different species of Carpet Beetle which are fabric pests, the Variegated Carpet Beetle and the Black Carpet Beetle.

It is only the larva of these species that feeds on fabrics such as woollen carpets (they do not attack synthetic carpets), fur, silk and feathers etc. The adults feed on pollen from flowers. Bringing fresh flowers into a building that contain the adult beetles is often the origin of the infestation.

They can fly and are attracted to light, often found clustered near windows. The larva eat small round holes in curtains, tapestry and clothes.
