How far do fire ants travel from their nest?

Whole colonies can move from place to place when disturbed, but they usually do not move far. The winged queen fire ants can fly quite a distance on their own. Studies have shown that the distance is limited to three miles or less, depending on their energy reserves.

How deep do fire ants penetrate the ground?

In general, fire ant workers live for four to six weeks. an extensive system of tunnels. Tunnels are built to improve air circulation throughout the colony. Tunnels have been found at a depth of 10 feet in some soils.

At what temperature do fire ants die?

At 12 inches below the surface, the coldest temperature recorded so far in 2014 at the University of Tennessee Trial Garden weather station in Knoxville was 37 degrees F. Ants at this depth have not yet experienced lethal temperatures.

How cold do you need to be to kill fire ants?

Ultimately, cold winter temperatures will limit how far northern fire ants can spread. Generally, minimum temperatures below 10 degrees F are needed to affect populations. Sustained cold temperatures in late fall or early winter can be expected to have a greater impact than later in the winter.

Where do fire ants go to find food?

Colonies can also migrate to inland locations. Fire ants feed when temperatures range from 22◦C (72◦F) to 36◦C (96◦F). When locating food resources, they deposit a trail pheromone that directs other worker ants to the site.
