I have 3 or 4 black ant hills in my back yard and I want to spray them with ( sfr ) should I spray and then stir the hill and spray again or just spray and not stir up the hill.
We recommend using 1 2/3 fl. oz of Permethrin SFR 36.8% per gallon of water for ant mounds.The label recommends that you treat each by applying 1-2 gallons of emulsion to each mound area by sprinkling the mound until it is wet and treat a 4 foot diameter circle around the mound so the ants do not move their mounds. Use the higher volume for mounds larger than 12". For best results, apply in cool weather, such as in early morning or late evening hours, but not in the heat of the day.
