How long after a flea bites does the spot go away?

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. ...Read more

What to do if I want these ugly marks to go away how long will it take to the flea bites go away?

Fleabites: Without a picture I can only assume that the ugly marks you are talking about represent scratch marks from scratching your flea bites.

The pyrethrin should work after several treatments. You can use 1 percent Hydrocortisone to remove your ugly scratch. ...Read more

How fast can I make my flea bites go away?

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. ...Read more

My son has what looks like flea bites. I have tried everything, they won't go away.

Talk to your vet: Talk to your vet if you think your pets/animals are the source of the infestation, since direct treatment of the pet is usually required. Getting rid of fleas that aren't obviously coming from your pets is hard. You may need to use a combination of insecticidal dusts or sprays, vacuuming, and cleaning. I hope you find the source and that your son feels better! ...Read more

Have had flea bites for the last few weeks and they are still on my legs how long does it take before they go? They won't stop bleeding?

Have had flea bites for the last few weeks and they are still on my legs how long does it take before they go? They won't stop bleeding?

Don't scratch.: When bites last that long, it's usually because the victim is scratching them, which keeps them inflamed - and also explains the bleeding, in your case. Soak a washcloth or old towel in warm water and apply it to your legs at least a couple of times a day. Take Allegra (fexofenadine) (available otc) to decrease the itching, and do whatever you have to do (wear boxing gloves?) to keep yourself from scratching. ...Read more

I think I may have flea bites, but not sure what nasty diseases are transmitted by dog or cat fleas in the u.S.?

I think I may have flea bites, but not sure what nasty diseases are transmitted by dog or cat fleas in the u.S.?

None (OK maybe one): No nasty diseases. Common bacteria can enter through breaks in the skin and cause infection (impetigo and cellulitis). Avoid scratching as that can introduce the bacteria. Oral antihistamines (Benadryl) and topical corticosteroids (cortisone) are helpful. If you live in rural New Mexico, Arizona, CA or Colorado there are rare cases of plague from infected rodent flea bites (squirrels, prairie dogs). ...Read more
