- 1). Cleanse the bites with cool, or even ice cold, water. If the bites are on you, and not a pet, avoid scratching the bites; scratching can open them up and cause infection. If the flea bites are on your pet, you won't easily be able to prevent your pet from scratching until the fleas are gone and bites are treated.
- 2). Apply a topical anti-itch medicine. These contain skin-numbing ingredients (analgesics) and/or hydrocortisone or antihistamine. For pets, consult your veterinarian. He can suggest the appropriate topical medicine for your pet. Many are available over the counter, but according to the University of Illinois College of Veterinary Medicine, pets may also require antibiotics along with steroids or antihistamines to clear up secondary bacterial infections from these bites.
- 3). Keep the flea bites clean and cool. Avoid wearing tight clothing over the bites and hot showers or baths until the bites have healed. Re-apply anti-itch creams when the bites start itching again (but no more frequently than the label suggests). Baking soda and water pastes or calamine lotion applied to bites (on humans) may also bring relief if you choose not to use topical antihistamines or hydrocortisone.
