Thermo-Lix® 16% IGR Fly Relief Tub

Start feeding before horn flies appear and continue use until cold weather marks the end of the horn fly season. Allow free choice to cattle. Cattle should consume 34 mg of (S)-Methoprene per 100 lb of animal body weight per month to achieve horn fly control. This is equivalent to an average of 1.6 oz. of Thermo-Lix 16% Fly Relief per 100 lb of animal body weight per day, which is equivalent to 16 oz per day for a 1,000 lb animal.
