Control In Pastures, Hayfields, and Barnyards
Granular fire ant baits are the best way to control fire ants in pastures and hayfields, but it is important to be sure the bait you buy is approved for use around grazing animals.
Fire ant baits are applied at very low rates, usually one to two pounds per acre. Some companies make spreaders that are specially designed to apply these low rates over large acreage. Depending on the level of control desired, the annual cost of controlling fire ants in a pasture or hay field can range from around $10 to $50 per acre.
See Extension Publication 2493, Control Fire Ants in Pastures, Hayfields, and Barnyards for recommended bait treatments and details on use. Read the section on Fire Ant Biology to learn more about how baits work.
Shipping Hay from Mississippi to Fire Any-Free Areas: All Mississippi counties are infested with imported fire ants and baled hay and straw must be certified as being free of fire ants before it can be shipped to uninfected areas. See the Imported Quarantine Map.
Before shipping hay or straw outside of the Imported Fire Ant Quarantine zone, contact the Mississippi Department of Agriculture’s Bureau of Plant Industry to arrange for inspection(s) and certification.
See the USDA, APHIS publication, Questions and Answers for Producers, Sellers, and Buyers of Baled Hay Moving from Areas Under Quarantine for Imported Fire Ant, for additional information about shipping baled hay and straw outside imported fire ant quarantined areas.

STARKVILLE, Miss. -- Southern farmers may never win the battle against imported fire ants, but aggressive tactics can slow the pests’ invasion, reduce damage and prevent further spread across the United States.
Jane Parish is an Extension/research professor with the Mississippi State University Extension Service and the Mississippi Agricultural and Forestry Experiment Station. She said cattle and hay producers have learned to live with and work around the troublesome ants since the pests arrived in the state almost a century ago.
STARKVILLE, Miss. -- People have many misconceptions on how to eliminate fire ant mounds and prevent them from coming back, and these erroneous beliefs hinder efforts to keep the harmful pest from spreading.
RAYMOND, Miss. -- Fire ants can be more than unwelcome guests in the home lawn; their stings can be dangerous for children and pets who share play areas with the pests.
Fire ant stings are characterized by sharp localized pain, swelling and intense itchiness that is just a short-lived nuisance for most. A raised red bump appears soon after the sting and soon turns into a sterile pustule that resembles a pimple. However, the ants’ venom can cause severe allergic reactions in some people and pets.
STARKVILLE, Miss. -- Tell Mississippians that fire ants have completely invaded the state, and they’ll probably shrug and say they already know that. Tell them the pain actually comes from a sting rather than a bite, and they’ll say it still hurts. But tell them how to get rid of the nasty critters, and they’re all ears.
The Mississippi State University Extension Service is organizing efforts to help residents Bite Back against fire ants. The solution is a simple two-part attack, but success comes in the long-term follow-through.
MISSISSIPPI STATE -- Fire ants are more than aptly named, given the reddish-orange color of their bodies and the painful, burning sting they can give.
Fire ants were unintentionally introduced to the United States from South America. The first documented release of fire ants occurred near Mobile, Alabama around 1918, and by the late 1930s, most of Mississippi had them.
Fire ants are very small and aggressive. When disturbed, they swarm, bite and sting, producing a painful or itchy pustule within hours.
