Black Carpet Beetle Beetles

Elimination

In the case where only a few adults were found inside, as these probably come from outside. A cleaning of the parts and window frames should be sufficient.

In the event that larvae are also found inside, a thorough cleaning of easily accessible strategic areas such as baseboards, the inner perimeter of wardrobes, etc., is necessary. Since they are structural insects, they can move from one floor to another and from one room to another through the structural voids. Inspect and clean behind electrical outlet fittings, switch fittings and around the pipe outlets.

In the case where larvae are found in natural fibre clothing, these clothing must be ventilated (or washed) and vacuumed on shelves or in drawers around them. To avoid a second infestation, the contents of the vacuum must be emptied into the bin, as the multiplication of insects could still continue there.

Finally, if the situation persists, the intervention of our certified technicians remains a safe and effective solution when the situation requires it.

Description and development

The adult Black Carpet Beetle (Attagenus unicolor ) is a small insect measuring 3.3 to 5.5 mm (1/8" to 3/16") in length. It can range from dark brown to black. The long, narrow larva has a cylindrical, cigar-shaped body with a tuft of hair at the end of its abdomen. It is approximately 12.5 mm (1/2") in length, and is brown or black in color.

Females lay some fifty eggs each on any material that may serve as food for the larvae. The adults, which reach maturity indoors, will venture out of doors to feed on pollen and nectar. After mating, the females return indoors to lay their eggs behind baseboard heaters, in hot air ducts, in attics, and other places. Adults have a lifespan of 30 to 60 days.

Habits

Larvae cause the most damage inside the home. They feed primarily on animal and plant-based fibers such as wool and cotton, as well as animal fur. As a result, it is strongly recommended to sweep and vacuum frequently, and to air out clothing and blankets on a regular basis. Larvae can also live in grain residues. It is therefore important to pay special attention to pet food.

Tips

Black Carpet Beetle larvae like confined spaces between two surfaces. For instance, a mattress lying directly on a carpet could be an attractive spot. Sofas, carpets, clothing, and materials containing animal fibers are popular targets of Black Carpet Beetle larvae. It is therefore essential to pay careful attention to these objects to prevent infestation.
