Update - after soaking my clothes, I squeezed all the liquid I could out of them…still too wet. Took them to the washing machine and put them through the spin cycle then hung to dry in the garage.
Had a gallon or more left in the bottom of the bucket and tote that I spread around the house. I also filled a spray bottle with some for stuff I may have forgotten. Obviously the residual from the washing machine went down the drain so it was wasted.
Things I’d do differently? Probably won’t do the soak method again because everything was too heavy and wet to hang up. Good thing my wife was out of town because using the washing machine gave the house a chemical smell. It’s better now.
Next time I’ll opt for a spray application using our lawn sprayer jut to get away from working the trigger on a spray bottle. Sticking with the concentrate and making my own dilution for the cost savings.
The good news is everything is treated and ready for the turkey hunt along with a bunch of clothes for yard work. Live and learn.
IMO, I don't know why, even after reading the threads here, but soaking your clothes with that much permethrin isn't really necessary. IMO a waste of a good repellant.
All I did, and anyone really needs to do, is to heavily wet/dampen their clothes, and other outer wear, with a good ~20-25% mix; ie 4-5 ounces of permethrin to 16-30 ounce of water, then air dry.
This will repel no see ems, chiggers and ticks, even Tennessee mosquitos, and it will last for 4-5 washing on clothing. Boots, gaiters, hats, etc items that don't get regularly washed even longer.
One treatment lasted me through:
A) 14 days in Zimbabwe followed by another consecutive 14 days in RSA. With daily washing.
B) 6 conservative weeks of turkey hunting. Eh, whenever I felt my hunting clothes really needed washing, maybe once or twice a week.
C) 10 conservative weeks of deer hunting. Maybe 30 total washings over this period. Refreshing with permethrin mixture about every 6-7 days depending on weather (a lot of rain, or amount of sweating, or number of washings) or (usually after about every 6 machine washings).
