Life Cycle of Black carpet beetle
Egg Laid singly or in clusters, these oval-shaped eggs are minute and might exhibit a pale whitish color. The potential for the forthcoming black carpet beetle lies dormant within.
Larva The larval black carpet beetle significantly differs from its adult form, possessing a voracious appetite. Its elongated body bears setae (hairlike structures), aiding in movement.
Pupal In this resting phase, the black carpet beetle is encased in a cocoon-like structure. This stage is a period of intense transformation, while it remains immobile and vulnerable.
Adult Emerging from the pupa, the adult black carpet beetle features hardened wing cases and functional reproductive organs. Distinctly colored and patterned, it now focuses on reproduction and dispersal.

Habitat Preferences of Black carpet beetle Through Different Life Stages
The larvae of black carpet beetle typically dwell in dark, undisturbed areas with access to natural fibers, often found in wool carpets, closets, or beneath furniture. In contrast, the adults tend to disperse, frequenting spaces with ample lighting such as windowsills or near artificial lights, searching for mating opportunities and laying eggs. To find larvae, one should inspect secluded locations, especially where dead insects, feathers, or accumulated hair and lint provide food sources. Examination of light-exposed surfaces and fixtures is recommended when seeking adult black carpet beetle, as they are attracted to light for mating and beginning the next generation's life cycle.

Textile Pest

Black carpet beetle larvae feed on a variety of animal products and can cause mild to severe damage to items such as woolen fabrics, carpets, upholstery, and clothing. Infestations often result in holes in textiles and can be quite troublesome to detect due to their cryptic lifestyle. Moreover, they can decrease the longevity and aesthetic value of infested items, leading to economic losses and the need for frequent replacements.

Buffalo carpet beetle
Buffalo carpet beetle

The adult common carpet beetle varies from about 2.5 - 4 mm in length. The antennae have eleven segments, three of which form a club, and the eyes are notched at the front. The head is black but is largely concealed under the prothorax, which is also black, liberally speckled with white scales apart from a band in the centre. The elytra (wing cases) are black with orange or reddish scales near the midline and variable but symmetric patches of white scales elsewhere. As the beetle gets older, the scales tend to get rubbed off so the beetle changes in appearance. The small white eggs are laid in batches of 30 to 60 and have projections which help them to adhere to carpet fibres. The larvae are brown and moult five times before pupating; the final instar larva is hairy and larger than the adult beetle. Pupation takes place in the last larval skin.
