Maxforce Granular Fly Bait can be applied as broadcast
Scatter application: Scatter the bait directly form the container onto dry level surfaces so that the individual granules lie near each other without forming small piles. * Bait stations: Place Granular Fly Bait in any bait stations. Secure bait stations at least 4 feet above the ground. Use 1 bait station to cover approximately 250 square feet. Add up to 1.6 ounces of bait per station. (Bait stations should be inaccessible to food producing animals, children and pets.) * Paint-on application: Mix 1.5 ounces of bait with 1 fl oz. warm water (3 lbs. bait in 1 quart of water) and stir thoroughly. Let stand for about 15 minutes until a paste consistency suitable for painting has formed. Apply paste with a brush to surfaces where flies rest, avoiding surfaces that are dusty. -
