Two ways to look at this. are you going to use it once in a while buy the sawyers. if you are outside and active buy in bulk and measure it out correctly, more is not better, exact is better. devise you a way to treat the clothes in bags then you hang them up and let them dry and then you wear them. washing machine action releases the chemical from your clothing so on the set of your clothing you are going to treat handwash them. get you several shirts and jeans socks, lots of socks and keep them separate. i would buy this or something like and a measuring container and some rubber gloves. after the stuff drys its just deadly to be bugs. you can treat your dogs too, check if you are also treating them with other stuff if you are not read the direction and treat them too, its farm friendly.
this will be your best protection and it looks like we are all going to need it, a buddy in georgia has already seen a big uptick
-)). doing this is not like squirting deet on you and heading to the woods this is a method that works much better, but its work.
