When I was a kid, my mother would lightly apply sevin dust on the lower part of my jeans before I spent a lot of time outside. Seemed to work really well at reducing the incidence of flea/tick bites and the stuff washes off quite readily.
I didn't know what Sevin dust is. It's the pesticide that the plant in the Bhopal disaster was making (MIC, precursor to carbaryl). Today's Sevin doesn't have the same chemicals in it that it used to though
