Flea, Mite, and Chigger Bites

Fleas, mites, and chiggers often bite humans. The bites are not serious. It may be hard to determine which type of insect caused the bite, or if the rash was caused by something else.

What are the symptoms of a flea, mite, or chigger bites?

Each person may experience symptoms differently. Symptoms may include:

  • Small, raised skin bumps

  • Pain or itching

  • Allergic reactions such as swelling or blistering

Call your healthcare provider if the symptoms don't go away or if you have any concerns or questions.

Treatment for bites

Treatment may include:

  • Cleaning the area well with soap and water

  • Using an antihistamine for itching, if needed

  • Putting cool compresses or ice wrapped in a cloth on the area to decrease itching and swelling

  • Using other creams for swelling or pain

  • Taking acetaminophen for discomfort, if needed

When should I call my healthcare provider?

Call your healthcare provider if you have any of the following:

  • Pain or itching that lasts

  • Signs of infection at the site of the bite, such as increased redness, warmth, swelling, or fluid leaking

  • Fever

Call 911 or your local emergency medical service (EMS) if you have signs of a severe allergic reaction. The signs are trouble breathing, tightness in the throat or chest, feeling faint, dizziness, hives (raised, red, itchy bumps) over a large part of the body, or nausea and vomiting.
