Fire Ants

  • Despite the name, this variety of ant is often actually black in color, according to AZ Ants. The worker fire ants are either black or red in color.

Worker fire ants are different sizes, with some being 1/4-inch long and others being only 1/16-inch long. Many fire ants are ground-nesting ants.

Black Ants
