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 densities in pastures can range from around 50 to more than 200 mounds per acre.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.

Fire ant mounds are common along fence lines where they are protected from grass-cutting equipment and other traffic, such as this mound in an Oktibbeha County, Mississippi, pasture on May 11, 2015. (Photo by MSU Ag Communications/Kevin Hudson)

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.

The biggest reason people have trouble controlling fire ants is that they only treat individual fire ant mounds. Individual mound treatments can be useful situationally, but need to be supplemented with broadcast treatments that will control all fire ants in all areas.

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.

Many dogs spend time outside and often share their play areas with fire ants. When disturbed, the ants sting and deliver venom that can cause severe allergic reactions for some pets and children. (Photo by MSU Ag Communications/Susan Collins-Smith)

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. -- Blake Layton grew up quail hunting in Simpson County and has seen the steady decline of quail as fire ant populations expanded across the state.

Layton, an entomologist with the Mississippi State University Extension Service, said the farm he grew up on has the same habitat as it did when he was a child, but it has more fire ants and fewer quail and other wildlife species.

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.
