The key difference between carpet beetle and bed bug bites lies in their cause and nature:
Bed bug bites are actual bites caused by the bed bug piercing the skin with its mouthparts to feed on human blood.

These bites typically appear as red, itchy welts or bumps, often arranged in a line or cluster. Bed bugs are nocturnal and feed at night, leaving bite marks on exposed skin areas such as arms, neck, and torso. The bites can cause irritation, swelling, and sometimes allergic reactions.
Carpet beetle vs bed bug bites
Carpet beetles do not bite. Instead, the irritation or rash that may resemble bites is caused by an allergic reaction to the tiny, bristly hairs on the larvae of carpet beetles. When these larvae crawl on human skin, their hairs can cause redness, itching, and rash-like welts that mimic bite marks. These reactions are due to contact with the larval hairs, not actual biting or feeding on blood.
Insect behavior Feeds on human blood Feeds on fibers, does not bite humans
Identifying whether you have bed bug bites or carpet beetle irritation is important for treatment: bed bug infestations require measures to eliminate blood-feeding insects, while carpet beetle issues focus on removing larvae and controlling allergic reactions.
