What Is A Fast Way To Get Rid Of Flea Bites On Humans?

I've heard to take garlic pills and it will prevent the fleas from biting you until all the fleas are gone.

I use the highest dosage of cortisone cream available.  If they don't go away, or become infected, a doctor can prescribe a dosage to completely heal them.  I was given this advice from my doctor, both when I had bites from chiggers, and later on when I was working as a pet groomer (and constantly was bitten by fleas).
 
Hope that is another suggestion you can use!

Use oatmeal in the bathtub. Put them in a small meshed bag, and place them in the tub. Soak in there for a little while. Oatmeal is great for stuff like this, especially if you are itching a lot. Or you can get some Aveeno, which is an oatmeal bath, but better packaged, and you don't need a mesh to contain the oatmeal. Hope this helps you out.
