Fire ants, like these Red Imported Fire Ants (Solenopsis invicta), are more aggressive than most native ant species and have a painful sting that is rarely life-threatening to humans and other large animals, but can kill smaller animals such as birds. Fire ants cannot be killed by flooding. If the ants sense a change in water levels in their nests, they will come together and form a huge ball that is able to float on the water and protects the queen in its center.Photo credit: Scott Bauer
