Thats a good point.The product i have says its odorless, im assuming they mean to game and not just our sub-par senses
Permethrine is for clothes only, once dry it is odorless. It will stay effective for weeks if clothes are stored in a black plastic bag out of the sun. It says good threw 2 washings but I wouldn't chance it. Deet is for use on your skin, but not in the eyes,The US Army says that it does not evaporate (hence, the need for DEET) ... so, that must be pretty odorless. ??
