The healing time for a flea bite varies widely based on the use of topical treatments and an individual’s reaction to the bites, according to The Travel Doctor. Being able to recognize and treat flea bites as well as eliminate the pests from indoor environments can go a long way to shortening healing time and preventing bites in the future.

According to LoveToKnow Skincare, flea bites most commonly occur on the ankles, knees, elbows, waist and armpits. Depending on a person’s reaction and sensitivity, a flea bite can produce localized itching, hives, a rash and swelling. To minimize discomfort, treat flea bites by washing them with soap and water and then patting them dry. Apply an ice pack to the area if swelling is present. Use an over-the-counter anti-itching cream such as hydrocortisone cream or calamine lotion. For extreme itchiness, use an antihistamine to control symptoms.

To promote healing, it is important to refrain from scratching flea bites, according to LoveToKnow Skincare. Scratching flea bites worsens the symptoms associated with them and can cause an infection, which greatly lengthens healing time.

According to the Travel Doctor, fleas breed where people live and sleep, making it important to treat the home for a flea infestation to prevent subsequent bites. Using insecticides and washing the bedding of humans and animals is typically the most effective in eradicating a flea infestation, according to LoveToKnow Skincare.
