When checking suspicious ant nests gently poke the nest with a long stick and observe the ants that come out.

Be careful not to get too close, as fire ants are aggressive. They swarm when disturbed and have a painful sting.

For help with identifying fire ants, see our fire ant identification video and fire ant photo gallery below.
