I just picked up some permethryn spray (5%, Walmart) to help keep the deer ticks away. I intend to use this in adition to deet. As I understand it permethryn is sprayed on cloths, not skin and lasts a could weeks. I also understand that it is an insecticide rather than a repelant.
Any thoughts about this stuff? I am less interested in possible health issues (the ticks scare me more than anything I am likely tolearn on that count) than how well the stuff works, and how long it lasts. I'd be using it in a day and weekend hiking conditions.
