Recognizing that fly control needs change depending on weather and activity level, Absorbine introduced UltraShield Red Insecticide & Repellent and UltraShield Sport Insecticide & Repellent in 32-ounce spray bottles last year. Now, both are available in gallon sizes. UltraShield Red delivers broad spectrum control for killing and repelling biting flies, such as horn flies, house flies and stable flies. UltraShield Sport is sweat-resistant for workouts and protects against flies and mosquitoes. For more information, check out http://www.absorbine.com/products/fly-control.
