Bed bug bites do have a resemblance to scabies. However, bed bugs bite at night and are slightly different in appearance. Bed bug bites are tiny raised welts that more closely resemble a bite than scabies, which looks more like a rash.
Scabies bites on occasion take on a crusty yellowish appearance and can form lesions.
Bed bugs have specially designed mout-hparts to pierce more deeply into the skin to get at the blood vessels. Scabies make their burrows and homes in the folds of the skin. Bed bug bites are often a series of raised bumps in a row as multiple insects feed right next to each other.
Bed bug bites appear overnight. Scabies bites are reported to itch more at night, but their biting and burrowing does not increase based upon the time of day.
Scabies bites are reportedly much more itchy and intense than bed bug bites.
