First Aid

Insect Bite

Most reactions to insect bites and stings are mild, causing little more than redness, itching, stinging or minor swelling. Rarely, insect bites and stings, such as from a bee, a wasp, a hornet, a fire ant or a scorpion, can result in severe reactions. Some insects also carry disease, such as West Nile virus.

For mild reactions

To take care of an insect bite or sting that causes a mild reaction:

  • Move to a safe area to avoid more bites or stings.
  • If needed, remove the stinger.
  • Wash the area with soap and water.
  • Apply a cool compress. Use a cloth dampened with cold water or filled with ice. This helps reduce pain and swelling. If the injury is on an arm or leg, elevate it.
  • Apply a cream, gel or lotion to the injured area. Use products containing ingredients such as hydrocortisone, pramoxine or lidocaine to help control pain. Use creams such as calamine lotion or those containing colloidal oatmeal or baking soda to help soothe itchy skin.
  • Use over-the-counter medications. Try a pain reliever, such as paracetamol  or ibuprofen, or an antihistamine

Usually, the signs and symptoms of a bite or sting disappear in a day or two. If you’re concerned — even if your reaction is minor — call your doctor.

When to seek emergency care

Call your local emergency number if the injured person experiences:

  • Difficulty breathing
  • Swelling of the lips, eyelids or throat
  • Dizziness, faintness or confusion
  • Rapid heartbeat
  • Hives
  • Nausea, cramps or vomiting

Take these actions immediately while waiting for medical help:

  • Loosen tight clothing and cover the person with a blanket. Don’t give him or her anything to drink.
  • Turn the person on a side to prevent choking if he or she is vomiting or bleeding from the mouth.
  • Begin CPR if the person shows no signs of circulation, such as breathing, coughing or movement.
