Description:Black Carpet Beetle
The adult is 2.8 to 5 mm long, black to reddish brown and covered with short, sparse pubescence
The larvae of the black carpet beetle, which may reach 12.7 mm in length, are very different from other carpet beetles larvae. They are elongate, carrot-shaped, golden to chocolate brown, and have a tuft of very long, curled, golden-brown hair at the tail end of their body.
The small, pearly-white egg can be deposited in the lint around skirtings, in the ductwork of hot-air heating systems, on wool clothing in storage, and in similar protected locations. The egg hatches in 6 to 11 days in warm weather, but may require an additional 5 to 16 days under cooler conditions.
The newly hatched larvae scavenge for food (they will eat dander, hair, and other small bits of food high in protein), avoid light, and move so slowly that they appear to be gliding. At room temperature, the larval life span ranges from 258 to 639 days. This variation is due largely to fluctuations in temperature, food quality, and relative humidity. The larvae may molt 5 to 11 times, and up to 20 times when conditions are unfavorable. The larval skins often are mistaken for the larvae themselves. The Black Carpet Beetle larvae pupate in the last larval skin, and the pupal period may extend from 6 to 24 days. The beetles may remain in the partially shed pupal skin from 2 to 20 days before emerging. Black carpet beetles usually overwinter in the larval stage.
Adults may live from 2 weeks to several months, but cause no damage in this stage. Unlike the larvae, they are attracted to light. They are active and often can be found around windows and outdoors on flowers, feeding on pollen in spring and summertime. The females commence egg laying in dark secluded places less than one week after emergence. A female can lay from 42 to 114 eggs, and averages around 50; she generally dies a few days after oviposition.Click here for Carpet Beetle products
