Valerie from Durango, Colorado writes
Hi Yield 38 Plus is labeled to eliminate ant mounds. According to the product label: Mound Drench- Mix 1.6 fl oz. (3 1/4 Tablespoons) of Hi Yield 38 Plus per 1 gallon of spray solution to make a 0.5% spray emulsion. Apply 1 to 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. Use higher volume for mounds larger than 12 inches. For best results, apply in cool weather such as in early morning or late evening hours, but not in the heat of the day.
