Fleas, Mites, and Chiggers

Fleas, mites, and chiggers often bite humans, but are not poisonous. It is sometimes difficult to assess which type of insect caused the bite, or if the rash is caused by poison ivy or other skin conditions.

The following are the most common symptoms of a flea, mite, or chigger bite. However, each individual may experience symptoms differently. Symptoms may include:

  • Small, raised skin lesions
  • Pain or itching
  • Dermatitis (inflammation of the skin)
  • Allergic-type reactions in hypersensitive persons with swelling or blistering
The symptoms of a flea, mite, or chigger bite may resemble other conditions or medical problems. Always consult your physician for a diagnosis.
