Appearance and Size

  • Adult carpet beetles are small in size and have an oval body structure, mainly between 2 and 3 long in length (about 1/10 to 1/8 of an inch). They have different colours like brown, black, yellow and orange. Moreover, their larval forms are long, hairy, and look like small cigars or bands.
  • The adult bed bug are bigger, ranging from 4 to 5 mm in length and appearing like small, flat and red-brown apple seeds. Nymph bed bugs are young, smooth and a lot smaller than larval carpet beetles, which have bristles.

Habitat

  • Carpet beetles often feed on natural material and tend to live in carpets, clothing, upholstered furniture, and sometimes in museums, feeding on old fabrics or taxidermy. The adults of this species consume pollen outside but lay eggs indoors. Larvae rely on wool, silk, leather, and the hair of animals as their food source.
  • Bed bugs like to stay in places where people hang out or sleep, mostly around your bed. They usually hide in seams of your mattress, bed joints, or even small nearby cracks. At night, they crawl out to bite and feed on blood.

Behavior

  • It is the larvae of the carpet beetle that cause the real issues, as they are the ones who feed during the day and do so by causing serious damage to fabrics and fibres. Adults are not responsible for the damage, and they do not bite.
  • Bed bugs are always active during the night and eat human blood only. They normally bite individuals while they sleep, which leads to the formation of itchy and red welts. Baby bed bugs carry out their daily activities in the same way as the adult bugs do, but in a lesser extent.
