Fire Ants
Fire Ants are often red but may appear black, and some fire ant species have a darker red coloring on their abdomen. Fire Ants are under a quarter of an inch with the queens being slightly larger. These are ground-dwelling ants that will build volcano-like mounds throughout your entire lawn, but especially in sunny areas. Their bites are quite irritating. What you may not know is that some people can have an allergic reaction to these bites that can cause them to go into anaphylactic shock. They are also a significant threat to those who can't get away from them, such as babies, the elderly, and the infirm.
