Varied Carpet Beetle

Identification & Biology of

Varied Carpet Beetle

The lifecycle of the varied carpet beetle starts as an egg. The larvae (known as the woolly bears) may moult over a dozen times, increasing in size each time. Upon the final moult its next life stage will be pupation. Pupation can vary in timing in relation to environmental causes & may well last over winter being ready to hatch out into adult form in the spring. Adult carpet beetles are expert aviators & will fly long distances to find suitable food & breeding sites.

live & how they affect you:

The varied carpet beetle prefers to lay their eggs away from direct sunlight, making under rarely moved furniture an ideal harbourage. The larvae eat Keratin, a protein which is found in the carpet fibres & will therefore quite literally eat holes in your carpet & cause serious damage. They will also lay eggs on other suitable materials such as clothing, leather goods, furniture & soft furnishings. They will appear through an open window in summer months. Remember it is not the adults themselves that cause the direct damage to carpets, but the larvae which comes from the eggs that they lay.

Control Measures for

Varied Carpet Beetle

To treat the varied carpet beetle it is usual practise to apply a thorough residual insecticide spray on all carpeted areas, paying accurate attention to infested areas as well as the floor/ wall junctions. The larvae stage can carry on for an entire year, so it is paramount that treatment is ample to ensure complete eradication. Luckily the adults are active enough to come into contact with the insecticide, thus helping to make applications successful. However follow up treatment is necessary as it is more difficult for the insecticides to infiltrate the egg cases.
