The furniture carpet beetle, also known as Anthrenus scrophulariae, is a species of beetle that belongs to the family Dermestidae. These insects are commonly found in homes and other buildings, where they can cause significant damage to furniture, carpets, and other household items. The furniture carpet beetle is a small, oval-shaped insect that is typically between 2-4 mm in length, with a brown or black body and a distinctive white or yellowish pattern on its back.
Life Cycle and Behavior
The life cycle of the furniture carpet beetle consists of four stages: egg, larva, pupa, and adult. Female beetles lay their eggs in dark, undisturbed areas, such as behind furniture or in carpets. The eggs hatch into larvae, which are the destructive stage of the insect. The larvae feed on a wide range of materials, including wool, silk, leather, and other animal-derived products. They can also feed on synthetic materials, such as nylon and polyester, although this is less common. As the larvae grow and develop, they molt several times, eventually reaching a length of up to 5 mm. After several weeks or months, the larvae pupate, emerging as adult beetles. Adult furniture carpet beetles are relatively short-lived, typically surviving for only a few weeks or months.
Diet and Damage
The furniture carpet beetle is a significant pest species, due to its ability to cause extensive damage to household items. The larvae are particularly destructive, as they feed on a wide range of materials. They can damage carpets, rugs, and upholstered furniture, as well as clothing, textiles, and other household items. In addition to the direct damage caused by the larvae, furniture carpet beetles can also stain surfaces with their feces and secretions. The adult beetles are also capable of flying, which allows them to disperse and infest new areas.
| Material | Degree of Damage |
|---|---|
| Wool | High |
| Silk | High |
| Leather | Moderate |
| Nylon | Low |
| Polyester | Low |
Prevention and Control
Preventing infestations of furniture carpet beetles requires a combination of good housekeeping practices and proactive measures. Regular vacuuming and cleaning can help to reduce the risk of infestation, as can dry cleaning or washing clothing and textiles. In addition, sealing any cracks or crevices around windows and doors can help to prevent adult beetles from entering the home. If an infestation is suspected, it’s essential to identify the species of beetle and take targeted measures to control the population. This may involve insecticides, traps, or other control methods.
Non-Chemical Control Methods
There are several non-chemical control methods that can be used to manage furniture carpet beetle infestations. These include heat treatment, which involves using a specialized heating unit to raise the temperature of the affected area to a level that is lethal to the beetles. Cold treatment is also effective, and involves using a specialized cooling unit to lower the temperature of the affected area. Traps can also be used to capture and remove adult beetles, reducing the risk of further infestation.
- Heat treatment: 120°F (49°C) for 2-3 hours
- Cold treatment: 0°F (-18°C) for 2-3 days
- Traps: sticky traps or pitfall traps

How can I identify a furniture carpet beetle infestation?
+A furniture carpet beetle infestation can be identified by the presence of small, oval-shaped beetles with a brown or black body and a distinctive white or yellowish pattern. The larvae are also visible, and can be found in dark, undisturbed areas such as behind furniture or in carpets. Other signs of infestation include damaged or stained surfaces, and the presence of beetle feces or secretions.
