Treating Insect Bites and Stings

When does an insect bite or sting require medical treatment? 

Dr. Mark Says:

Bites from mosquitoes, gnats and no-see-ums are usually harmless, but stings from bees, wasps, hornets, yellow jackets and fire ants can be troublesome. Fortunately, most people react with just itching or stinging and mild swelling that disappears in about a day. A small percentage have severe reactions, such as swelling of the lips or throat, difficulty breathing, abdominal pain, faintness or dizziness, confusion, hives, or rapid heartbeat. If these occur, call 9-1-1 immediately.

While waiting for assistance:

  • If the person is carrying an auto-injector of epinephrine (such as an EpiPen) follow application instructions and massage the area for 10 seconds.
  • Give the person an antihistamine pill (such as Benadryl or Tylenol Severe Allergy), if he/she can swallow it.
  • Have the person lie on his/her back with feet raised, and loosen clothing.
  • Begin CPR if person is not breathing or moving.
