There are only two main types of Carpet beetles, the Black and the Variegated.
- Female adults lay eggs in dark, undisturbed areas.
- Eggs hatch into reddish-brown larvae. Each larva is covered with tufted hairs.
- It is the larvae that cause the damage.
- Once fully fed the larvae change into an immobile pupal state, then after several weeks into adults.
Habits and Habitats
- Adults do not cause further damage, but they often re-infest homes when they are brought in on cut flowers.
- Carpet Beetles like to live in woollen materials, felt, fur, upholstery, stuffed animals as well as carpets.
- Infestations usually occur in undisturbed areas, such as below items of heavy furniture, or the perimeter of carpets.
- It is possible for them to damage synthetic carpets, especially if the carpet is heavily soiled with food debris or urine.
- Carpet Beetle do not carry disease organisms harmful to man or animal, but are pests because of the damage inflicted on materials in homes.
- Thorough vacuuming of infected areas followed by the application of a residual insecticide spray will usually control carpet beetles.
- Many synthetic and woollen carpets are now treated with insecticides as the time of manufacture to make them resistant to carpet beetle attack.
