Permethrin and Repellents as Clothing Impregnants for Protection from the Lone Star Tick123

When permethrin, deet, or a mixture (M-1960) containing 30% 2-butyl-2-ethyl-1,3-propanediol, 30% benzyl benzoate, 30% N-butyl acetonilide and 10% nonionic emulsifier was used to treat military fatigue uniforms for control of all stages of Amblyomma americanum (L.), permethrin was somewhat more effective than deet and about as effective as M-1960. Test subjects preferred the permethrin-treated clothing to clothing treated with M-1960 or deet because it did not have an odor, was not irritating, and was effective.
