Residual Surface Sprays

Residual sprays applied to walls, ceilings, partitions, stanchions, posts and other fly resting places are still the "mainstay" of fly control on livestock farms. These sprays are much more effective in stanchion barns than in loose-housing management where surfaces on which flies alight are minimal and buildings are very open. Also, barn surfaces vary in the amount of spray that should be applied to them. Smooth surfaces require less spray than rough, porous surfaces. Thoroughly wet the surface to the point of runoff at low pressures of 80 to 100 pounds per square inch using a power sprayer or good proportioned type sprayer. Avoid contamination of feed and water. Cover drinking cups and mangers during spraying. Never spray in the milk house. Do not contaminate milk and milk utensils. Follow label directions.

(a) cyfluthrin-use 19 grams Tempo 20 percent WP per 1,000 square feet as a general surface spray in sufficient water to adequately cover the area being treated (normally two gallons), but which will not allow dripping or runoff to occur. Remove animals before spraying. Keep all animals out of treated buildings for at least four hours.

(b) diazinon-mix one half pound Dryzon 50 percent WP in 6.25 gallons of water. Apply one gallon per 350 to 750 square feet of area, depending on the surface treated, as an overall spray to ceilings and walls of barns and animal sleeping quarters (except dairy barns, milkrooms and poultry houses). Longer residual control may be obtained by increasing the rate to 1 pound per 6.25 gallons of water.

(c) dimethoate-mix one gallon Cygon 23.4 percent EC per 25 gallons of water. Apply one to two gallons of finished spray per 1,000 square feet of interior and exterior surfaces. Remove animals before spraying. Keep animals out of treated buildings for at least four hours.

(d) fenvalerate-mix one quart Ectrin 10 percent WDL in 10 gallons of water. Apply two gallons of finished spray per 1,000 square feet. (Use only in horse or swine buildings.) Remove animals before spraying. Do not contaminate feed or water.

(e) lambdacyhalothrin-mix one water soluble packet Grenade 10% WP in sufficient water (see label). For use in dairy barns, poultry buildings, swine buildings, animal hospital pens and dog kennels. Reapply at 21 day intervals if necessary.

(f) methoxychlor-mix one pound Marlate 50 percent WP in 2.5 gallons. Apply one gallon of finished spray per 500 square feet of surface. Dairy animals should not be present while spraying. Do not use in poultry houses.

(g) permethrin-mix 6.67 ounces Atroban or Permaban 25 percent WP per 10 gallons of water. Mix six ounces Ectiban or Insectrin 25 percent WP per 11 gallons of water. Apply one gallon of finished spray per 750 square feet of surface as a coarse, wet spray.

permethrin-mix one quart Ectiban, Hard Hitter, Insectrin 5.7 percent EC per 12.5 gallons of water. Apply one gallon of finished spray per 750 square feet of surface as a coarse, wet spray.

permethrin-mix four fluid ounces GardStar 40 percent EC to 10 gallons of water. Spray surface until wet or 1 gallon per 750 to 1,000 square feet.

permethrin-mix one quart Permectrin II 10 percent EC per 25 gallons of water. Apply one gallon of finished spray per 750 square feet of surface as a coarse, wet spray.

permethrin-mix one pint Atroban, Expar or Permaban 11 percent EC to 10 gallons of water. Apply finished spray to surfaces where flies rest at the rate of one gallon per 750 to 1,000 square feet or to the point of runoff. Do not apply more often than once every two weeks.

(h) tetrachlorvinphos-mix four to eight pounds Rabon 50 percent WP per 25 gallons of water. Apply one gallon of finished spray per 500 to 1,000 square feet of surface to the point of runoff. Keep all animals out of treated building for at least four hours.

(i) tetrachlorvinphos and dichlorvos-mix one gallon Ravap 28.3 percent EC per 25 gallons of water. Apply one gallon of finished spray per 500 to 1,000 square feet of walls, ceilings or other areas where flies rest or congregate. Keep all animals out of treated buildings for at least four hours.

(j) Trichlorfon - Mix 3 pounds of Dipterex 80 SP in 24 gallons of water. Apply one gallon of finished spray per 500 square feet, or to the point of runoff (for use in dairy and cattle barns and poultry houses.) Remove animals from facility before making applications. Allow spray to dry before re-stocking facility. Do not contaminate feed, water, feed handling equipment or milk handling equipment. Repeat applications every one to two weeks or as needed.
