I purchased DurationTM Permethrin 10% Concentrate from Amazon. *It is intended for use as a soak but I deluted it to .5% and use it as a spray like Sawyers. It is $30 for 8 oz. Mixed 20 to 1 it will make 168 oz of .5% spray or equal to 7 of the 24 oz bottles of Sawyers. Thats $30 vs $90.
I had picked off probably 50 (only about 6 or so embedded, most crawling on skin or my clothes) or more ticks early this spring before using this solution. Haven't had one tick or chigger on me since and I hunted spring gobbler season and have been in the woods a lot since.
I sprayed one set of hunting clothes, pants, socks, shirt and hat and wore them them all of spring gobbler season without reapplying spray. Suppose to last for six washings. I didn't do too much washing, since gobblers can't smell.
The area I live in (woods) Southern, Illinois is ate up with ticks every yr.
