When treating for chinch bugs with Bifen IT, it is recommended that you do a second treatment 21-30 days after the first treatment. You will use 1 fl. oz. of product per gallon of water. This will treat 1000 square feet. Be sure to water the product in at least 0.5 inches after it has been applied.
