How to get rid of Carpet Beetles

What are carpet beetles?

Before we learn how to get rid of carpet beetles, let’s look at what one is. Carpet beetles are oval-shaped and difficult to spot as they are only 2 to 4mm long. As is so often the case, it is the larva that does all the damage. These are mostly brown, with white or yellow markings and are covered in short, bristly hairs, hence their well-known ‘woolly bear’ moniker.

What causes carpet beetles?

Adult beetles dwell mainly outdoors, but after mating, the female searches out a place to lay her eggs. A prime location is a disused birds nest that may be in your loft or lodged in a chimney, or some loose blankets or carpets that lie undisturbed.

These places provide an abundant supply of food for the developing larvae, whose diet focuses on any natural material such as hair, feathers, wool, cotton or linen.

Once the supply runs out the larvae will search for food anywhere in your home to satisfy their voracious appetites. Considering that the larval stage can last up to three years, an enormous amount of damage can be done in this time.

  3. Throw out any unwanted carpets and blankets
