I remember seeing and mixing 10% Permethrin,a couple of years ago.
We bought,a few of us on a site[i thought it was here/],bought it at 10% and mixed it to .5%. The mixes we were told were:
1 [10%] Permethrin to 19 parts of water.
OR
51/2 ozs. to 128 ozs. of water.
At this ratio,it was used to make the hunting coat and or pants,some what wet and left to dry,before wearing! I used a 2 gallon pump sprayer.
I still don't know if this stuff is ok to have constant skin contact,so i don't apply it to garments close to my skin. Of course,thats me? I use other sprays for closer contact.
Also,after treating my coat and other garments and it dried,i could not smell the treatment.
Any how,i just thought i would post this,
