Fire Ant Bites
Horses can sometimes accidentally step on, roll over on, or stand too close to mounds constructed by fire ants (Solenopsis invicta) while turnout out in pastures. When fire ant hills are disturbed, the ants rapidly respond by attacking the cause of the disturbance with painful bites and stings. A fire ant delivers a very painful simultaneous bite and sting composed of piperidine alkaloids.
