Beating Fire Ants This Fall

Falling into fall sounds like a great idea — unless falling includes a run in with the Imported Fire Ant. Pest-proofing your home is a multi-step process that includes treating outdoor areas as well as indoor areas. The following five tips can help you and your family avoid unwanted visitors this fall.

Fall is a great time to treat fire ants.

“Fall is a great time to treat fire ants,” Dr. Kathy Flanders, an Alabama Cooperative Extension Entomologist said. “Fall temperatures are perfect for fire ant activity and foraging, making it an opportune time to put out fire ant bait.”

While the warm weather is rolling out and cooler air moves in, fire ants are still actively foraging. Fire ants look for protein-rich foods all year, but especially in the late spring and early fall.  Foragers usually continue searching for food until temperatures drop below 75 degrees Fahrenheit. Using treatment plants like the Two-Step Method can provide specific and continued control of fire ants, in a cost-effective way.

Fall is an important time to protect livestock from fire ants.

Researchers have developed an interactive, customized management tool for managing fire ants in pastures and fields. Use of the management tool will allow for a cost-effective application of pesticides in hopes of knocking out a significant portion of the fire ant population before the winter season. There are also resources available with specific guidelines for management of fire ants in a livestock operation.

Dragging pastures is not a sure or complete fire ant control method, but dragging a pasture before a freeze could help control the fire ant spread in that area.

High traffic areas can include calving areas and hay storage areas. Flanders said young livestock are very vulnerable targets, but caution and diligent treatment can help prevent damage by fire ants.

Fire ants will be looking for a warm place to overwinter.

Double-checking door seals, pipe coverings and concrete foundations can help prevent a home invasion in the winter. As temperatures drop, fire ants begin searching for warm places to spend the cold months. Often, this means mounds inside the house or built against the foundation.

Alabama Cooperative Extension professionals developed management options for treating fire ants inside homes and buildings. The first and most important suggestion: treat fire ants in the surrounding landscape to prevent fire ant infestations near the home. This publication includes product names and uses, and tips for fire ant control in the home.

Fire ants may be in your pile of leaves, wood stack or winter garden.

Outdoor temperatures determine the amount of activity present in a fire ant mound. When the temperatures are right, leaf or compost piles, wood stacks and winter gardens are all likely hiding places for fire ants.

Flanders said it is important to check for fire ants before playing, working or carrying wood inside. A proactive approach to controlling fire ants in these areas would be best. This is also a time to consider a slow-acting bait for continued control going into the cold season. Treat the areas before piling up leaves to play in or for compost, treat your preferred firewood location and treat your garden before planting.

Working with neighbors or surrounding landowners can boost your chances of knocking a dent in the population.

Fire ant control is more effective when larger areas are treated. When an 80-90% control rate is acceptable, consider participating in a community- or neighborhood-wide treatment program. If the problem is widespread, a large treatment plan could be more effective than treating in small areas. Flanders said Extension professionals have developed a community-wide management program that is available for use and implementation. Find the program here.
