Depends: If uninfected, they should heal within a week. If irritated and scratched, they will last longer, scar up and may become infected. Avoid scratching and apply an antibiotic ointment and keep them clean to enhance healing. May also apply a "liquid bandaid" that looks like clear nail polish to slow itching and infection. Topical Benadryl (diphenhydramine) is useless as are steroids.

Up to you: If you are allergic to the bites, then they will itch for weeks. If you scratch them, they will itch until you quit scratching them. They can cause hard bumps called nodules if you continue to rub or scratch. Also, are the fleas still around? Other bites can look like flea bites and last a long time, such as scabies and other mites. Hydrocortisone cream and oral Benadryl (diphenhydramine) will help the itch.

Depends on early Rx: Treating flea bites promptly with cool compresses, 1 % hydrocortisone/calmine and perhaps an oral antihistamine (claritin/zyrtec) and tending to the scar after the lesions heal will minimize their appearance. If they are severe, exfoliation, moisturizing, sun block and over the counter anti scar treatment (mederma/neosporin scar solution) are starters for fading the scars.

Depends...: ...On how many you have and how long you've had them. With aggressive treatment by a dermatologist, they can clear in as little as a few days, but no reputable doctor can pinpoint a timeframe; everyone responds differently to treatment. Obviously, you need to make sure the source of the fleas has been eliminated so you don't get a whole new set of bites after the present ones clear.

It depends: If you are not getting rid of the source of the fleas, you will keep getting them. Use an appropriate pesticide (safe around animals) and have your pets treated as well. Avoid scratching and keep all bites clean. Caladryl clear may help prevent itching, and allow them to heal more quickly.
