Management — Treatment (Agriculture)

Non-Chemical Control

  • Scheduling cow fertility programs to ensure that calving occurs during cooler weather when fire ants are less active (soil temperature below 65 degrees F).

  • Shallow disking of pastures and rangeland or dragging heavy objects such as railroad ties across pastures, particularly after rotating livestock. This temporarily flattens tall, hardened mounds, although it seldom eliminates fire ants. Dragging a pasture during freezing weather may reduce populations by exposing the ants. Dragging also scatters manure that harbors fly larvae upon which fire ants feed.

  • Using disc-type (Kountz) cutters designed to withstand the impact of fire ant mounds to reduce equipment damage.

  • Using mechanized balers and bale movers to reduce human contact with infested bales. Tightly-bound bales may be more difficult for fire ant colonies to infest than loose bales.

  • Removing hay bales from the field immediately to prevent ants from infesting them, particularly when rain is expected.

  • Storing bales off the ground or in an area treated for ants. (Note: The quarantine prohibits the shipment of hay from infested to uninfested counties without certificates. Call your Department of Agriculture or Plant Board to certify that hay shipments are ant-free).
