Simply get two sets of rhinoskin and wear under your clothes. Then I use my own natural mix insect repellent. 7% Catnip oil, 5% Rosemary Oil, 5% Cornmint Oil,an emulsifier, a dab of glycerin and the rest is water. The menthol in the cornmint oil makes is smell good and cools you down. I spray very liberally. I mix it in 500ml batches. You can buy a similar mix for $15 for 16 fluid ounces, I am down to $6 for the same amount. The catnip is more effective than Deet (see public studies) and the rest doesn't make you very attractive for insects. The rhinoskin gives you additional piece of mind.
I would not put insecticides into my clothing. And you wonder why you all get allergies?
Since I am very allergic to poison ivy, I try not to use my clothing multiple times without washing, especially in spring. I use jewelweed soap to precondition for that and jewelweed spray for the now very few little outbreaks.
