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. Also see Extension Publication 2733, Imported Fire Ant-Free Hay Certification in Mississippi.

Mississippi has an abundance of bugs, especially in the warmer months. We are all familiar with mosquitoes, bumblebees, and house flies. But I bet there are bugs around your house and yard that you can’t identify. (Photo by Blake Layton)

Just when we think we’ve conquered our tiny foes, it rains, and fresh fire ant mounds pop up in our yard.

Like many tasks around the house, fighting fire ants feels like a constant battle. My husband and I finally started seeing some progress when we followed recommendations from MSU Extension’s expert, Dr. Blake Layton. (Yeah, that’s a side benefit of my job, learning all kinds of practical information!)

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.
