I use OFF to keep from being biten.

But if you get bit/stung - feed the flying indigenous wildlife, I highly recommend Blue Star Ointment. It's camphor in petro-jelly. Just smear it on the bite area. You may notice skin reddening in the area, but no worries. I'm one of those that swells up with welts from mosquitos, but this stuff takes the itch out in just a few seconds. It even works on fire ant bites - although with these evil buggers, a second application may be necessary. If I had the ointment before I moved here, I wouldn't have scratched myself silly, and now have lots of scars on my legs and arms. I was given a jar of the ointment as a housewarming gift from my realtor when I got bitten by fire ants while we were house hunting (I had bought the house with the fire ant hill).

I also waged chemical warfare on the fire ant hill, and after three years they were killed off.

Blue Star Ointment - good stuff. Frankly I hope it's still out there, I'm almost out of my original pot.
