Before my stepson spent a summer in Costa Rica taking courses at UGA's campus and working, I gave him a pump spray can of 99.9% Deet. His classmates looked sideways at him for carrying it. Their intentions were to use "natural" repellents. After seeing the introductory video to the insect hazards of the jungles, including Bot flies, they lined up with extended hands asking for a bit o'deet. It's been Seresto collars for my dogs during hunting season, Deet for me and Sawyer's for my clothes when I'm in the woods. The Seresto collar mfg. claims that the collar can be worn when dogs get wet; However, if dogs get in a lot of water while hunting, the effective life of the collar is reduced more severely than the mfg. would have one to believe. My vet advised to remove it before the hunt and place it back on afterwards if the dogs get in water. My dogs could find water during a drought in the Sahara. Gil
