Hello folks. I think i found out a way to make cheap Permethrin. Here are my thoughts:

The ordinary spray thats marketed for clothes and equipment is available at approximately $21 for 24 oz (.2 gallons) of 0.5% Permethrin.

In the gardening section, we have an 8 oz bottle of 13.3 percent Permethrin for $15. We can just dilute this Permethrin down to .5 percent Permethrin by adding water to make 212.8 oz (1.6 gallons) of 0.5 percent permethrin total.

I know this shit might cause cancer but i hate ticks more. This is clearly a superior option for Permethrin. What do you folks think.
