insect bites

Last reviewed 10/2020

This is a cutaneous reaction to a stinging or biting arthropod, usually resulting in itching and occasionally acting as a vector of disease.

Clinically insect bites are generally:

  • itchy
  • urticated papules - there may be a central punctum; they may be excoriated; occasionally blisters are associated
  • bites often occur in groups; often asymmetrical
  • more than one family member may be affected
  • may be secondary bacterial infection
  • papular urticaria may occur as a complication of any insect bite(s)
