I have a bottle of 10% Permethrin emulsifiable concentrate with petroleum distillate as solvent, and a bottle of 1% deltamethrin water-based suspension concentrate.
My bedroom is infested with psocids. If I want a residual effect lasting 7 months, what should the concentration be?
Most furniture in my bedroom is wooden, I may apply turpentine or wooden floor polish(which contains wax) to the absorbent wooden surfaces.

I may rate your answer later because I have no personal computer at home.
