Animal flea collars do not work, or have never for me cause I tried em while hunting. The Permethrin that Mau Mau mentioned works pretty well. When in the woods or in areas where ticks are mking their home, I always tie my pants cuffs and use a good bug spray, usually the highest concentrate of Deet I can get. And lastly, when I get home I immediately wash the clothes worn in hot water and I take a really hot shower and do a good search of my body for ticks. I can deal pretty well with ticks and mosquitos, its the sand gnats that I reall dispise.
