itchy, red, swollen, painful,flea bite

I don't know about a 'remedy', but to keep them nasty, hellish critters at bay...I use, AVON "SKINS SO SOFT'. It's greasy, so limit it on your body. I was told that it is a good repellant and it works wonders for me. I have some on my legs and top of feet and no bites tonight. It won't get rid of your bites, but it repells them from having a feast on your body. Good Luck.
