Answer:

Extinguish Plus Fire Ant Bait would be a good choice for you. Extinguish Plus can be used on pasture land and there are no grazing restrictions for companion animals. Below you will see the grazing info available on the Extinguish Plus product label. 
 
Extinguish Plus combines the power of hydramethylnon with an insect growth regulator (IGR) to kill fire ant workers and prevent queens from laying fertile eggs. The result is complete fire ant colony control. Extinguish Plus Fire Ant Bait is best used in the spring or early fall, or whenever fire ants are active. The ants will feed off Extinuish Plus and spread the bait throughout the entire colony, halting the infestation within weeks. Extinguish Fire Ant Bait can be used indoors and outdoors on lawns, pastureland, rangeland, landscaped areas, and golf courses.
 
EXTINGUISH PLUS may be applied to grass forage (pastures and rangeland) for the control of fire ants only in the following states: Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, New Mexico, North Carolina, Oklahoma, South Carolina,
Tennessee, Texas, and Virginia. Use on grass forage (pastures and rangeland) in states other than those listed is unlawful. See Outdoor Use table for application directions. Do not exceed 8 pounds per acre per year or more than 4 times a year, with a
minimum re-treatment interval of 90 days. Do not bale and cut treated pastures and rangelands for 7 days following application. These cutting and baling hay restrictions for pasture and rangeland do not apply when the treated pasture and rangeland is used solely to support COMPANION ANIMALS (e.g., horses, llamas, etc.). Companion animals grazed on treated areas cannot be used for food or feed.
