Application Instructions

Each bottle contains approximately 15 fl. oz. of FBP23™ ES, which treats 30,000 to 50,000 square feet of floor area. Apply FBP23™ ES at a rate of 1.5 to 2 fl. oz. per 5,000 square feet of floor area. Although FBP23™ ES can be applied with conventional equipment of the user’s choice, there must not be any fitter or screen smaller than 50 microns, which would prevent the active ingredient from passing. Be sure to agitate the contents of the bottle by shaking vigorously to re-suspend any sediment that formed in the bottom. Add the contents of the bottle to sufficient water in a mix tank to ensure even coverage over the treated area. Add a small amount of water to the emptied bottle, replace the cap, and shake the bottle again. Add this “rinse” water to the mix tank.

Apply the spray to walls, floors, posts, where the greatest numbers of pests are located. This is a contact infection material. Re-treat between flocks or in areas where darkling beetles accumulate. There is no restriction on the total maximum amount of FBP23™ ES that may be applied in a year. The product is only to be applied to poultry or livestock manure that is to be composted.
