Insect Bites and Stings and Spider Bites - Home Treatment

(continued)

Prevent a skin infection

Wash the area with soap and water.
After washing, wipe the area with rubbing alcohol or first-aid antiseptic.
Trim fingernails to prevent scratching, which can lead to infection.
Do not break any blisters that develop.
If a bite becomes irritated, apply an antibiotic ointment, such as bacitracin or polymyxin B sulfate, and cover it with an adhesive bandage. The ointment will keep the bite from sticking to the bandage. Note: Stop using the ointment if the skin under the bandage begins to itch or a rash develops. The ointment may be causing a skin reaction.

For home treatment of lice, scabies, tick bites or bedbugs, see the topics Lice, Scabies, or Tick Bites or information about bedbugs.
