Directions for Use:. It is violation of Federal Law to use this product in a manner inconsistent with its labeling. This product is designed for use in all Black Flag?, Burgess, Cutter? or Repel? thermal powered foggers (sold separately). Use Black Flag Fogging Insecticide Formula 2 to kill mosquitoes that may carry West Nile Virus and biting flies including house flies, stable flies, black flies and biting midges. Works in and around your garden, lawn, deck, patio or swimming pool. When used in Black Flag, Burgess, Cutter or Repel thermal foggers, Black Flag Fogging Insecticide Formula 2 becomes a virtually odor-free fog that moves through the air to penetrate dense foliage to kill listed insects where they live and hide. Before you Fog: Remove or cover dishes, utensils, food-processing equipment, and food-preparation surfaces, or wash them before use. Remove pets, birds and cover fish aquariums and ornamental fish ponds before spraying, and turn aquariums systems off. When and How to Fog:. 1. Fog in late afternoon or early dusk when wind is calm and insect activity is increasing. Do not treat if wind is greater than 5 mph because the fog will dissipate too quickly. 2. Pour Black Flag Fogging Insecticide Formula 2 undiluted into the Black Flag, Burgess, Cutter or Repel thermal fogger (sold separately). 3. Fog at the rate of 1.5 fluid ounces per 1,000 sq. ft. (a 25' x 40' area) [0.75 fluid ounces per 500 sq. ft. (a 25' x 20' area)]. For best results, thoroughly fog shrubs, groundcovers, and lawn areas surrounding the area you wish to occupy. Do not wet plants to point of runoff or drip. Allow the fog to penetrate foliage where mosquitoes and biting flies rest. Create a "fogged buffer zone" as your space allows. Apply one pump of the fogger trigger every 3 to 4 seconds to obtain the best fog quality. It will take approximately 30 pumps of the fogger trigger to fog 1,000 sq. ft. [15 pumps of the fogger trigger to fog 500 sq. ft.]. A 5,000 sq. ft. lawn and garden area can be treated in 10 minutes. 1 qt. of product will be required to treat 1/2 acre.
