Yep, ger the concentrated stuff, mix it up, and save a lot of money. Spray outside clothing (clothing used for hiking, fishing, walking etc) and it lasts for several washings. Don’t need to slather on skin, just do pants, socks maybe, but t definitely shoes, overcoat or overshirt. A bittke,of,concentrate lasts a long g time. MIx it 1 to 10 ratio.
I always dress in two layers and treat the outside layer. Keeps the permethrin off our skin.
Mr mm had a treated shirt and I found a tick on his back that was dead, and I have found dead ticks on my cruddy sweatpants even a couple weeks after them having been treated. I also tuck in my underlayer into the tops of my socks and they tuck the sweatpants into the tops of my treated boots. I have noticed ticks have a very decided preference for climbing up.
And we still do tick checks after being outside.
