I just made up a gallon using the following
4 cups (32 oz). apple cider vinegar
2 oz permethrin (from tractor supply)
4 cups vetrolin shine 32oz (I use healthy coat if I have that on hand)
2 tablespoons liquid glycerin soap
2 tablespoons baby oil
water to 1 gallon.
Haven’t used it yet
OK- so what are you using?
