Read label thoroughly for specific uses.
Amdro Pro (0.73% hydramethylnon) – May be applied to grass forage (pasture and rangeland) for the control of fire ants in some southern states.

Clinch (0.011% abamectin) – Speed of control similar to Amdro Pro, but label is more restrictive than Amdro Pro. Controls fire ants in citrus, almonds, walnuts, potatoes, vegetables, around barns and equipment, and chicken houses. Do not use in pastures or rangeland grazed by cattle, sheep, or other domestic animals (including horses), or around chicken houses where birds are allowed outdoor range.
Esteem (0.5% pyriproxyfen) – Esteem can be used in hay pastures or with livestock used for food or feed production. Esteem may also be used in select vegetables, and tree or vine fruits, but refer to the label for specifics. Relatively slow, 1-3 months applied in spring, 3-6 months in fall.
Esteem “Skip Swath”– In Texas only, can be applied as “skip swath” using suitable ground equipment such as a Herd GT-77 model seeder (http://www.kascomfg.com/kasco_seeders_g77_atv.html) to apply full rate (2.0 lb product/acre) to every other swath, thereby applying 1.0 lb/acre.

They are relatively quick-killing and are formulated as aerosols, liquids, dusts (Ortho® Orthene® Fire Ant Killer or Surrender Fire Ant Killer) or granules. They can be applied as mound treatments or surface treatment. Follow label directions.
