Can you get cellulite from an insect bite? Everything you need to know to avoid it

Bites from mosquitoes, wasps, spiders and other insects can break your skin, leaving an opening for bacteria to enter.

What is cellulite?

Cellulitis is a skin infection that can be caused by many types of bacteria. It causes swelling, redness and pain in the infected area. If you don’t treat cellulite, it can spread and cause serious problems affecting your joints, bones, blood, or heart. Cellulitis can be treated by your healthcare provider with antibiotics.

Although cellulitis can be caused by many types of bacteria, the two most common types belong to group A. Streptococcus and Staphylococcus aureus. These bacteria live on your skin and under your fingernails.

Most insect bites are mild and can be treated at home. However, insect bites cause a break in the skin which can allow bacteria to enter. If you scratch an insect bite, you can transfer bacteria from under your fingernails or the surrounding skin into the wound.

If you are bitten by an insect, treat it immediately to avoid complications like cellulitis.

  • Move away from the area to avoid being bitten or stung.
  • If you see a stinger, remove it from your skin.
  • Wash the insect bite area with soap and water.
  • Reduce pain and swelling by applying a cold cloth to the area for 10-20 minutes.
  • If the bite or sting is on your arm or leg, elevate the limb to help reduce swelling.
  • Apply calamine lotion, baking soda paste, or hydrocortisone cream to the area several times a day.
  • Take an antihistamine like cetirizine, fexofenadine, or loratadine to help reduce itching.
  • Use an over-the-counter pain reliever if needed.

What is cellulitis caused by an insect bite?

A bug bite alone won’t give you cellulitis. Insects do not transmit cellulitis-causing bacteria through their bites or stings. However, the break in your skin caused by the bite or sting can give bacteria a chance to get inside your body and cause an infection. These types of bacteria usually live on your skin, nose, and mouth, even if you are healthy.
