Bifen IT should only be applied to interior cracks and crevices quarterly (where floor meets the wall) and monthly to listed exterior areas as directed.
When using Bifen IT for armyworms irrigation is not necessary. You actually need to try to have no irrigation or rainfall for at least 24 hours after the application. Under chinch bug treatment it does advice that in order to optimize the penetration of the insecticide you can water the area prior to the treatment. If grass is being kept at a long mowing height or if the thatch layer is excessive, use higher volume treatments. It may be necessary to use higher application rates (up to 1 fluid oz. per 1000 square feet) to control populations made up of both adults and nymphs in mid-summer. Complete instructions are on the product label for each pest as well.
