One of the most common types of fire ants in the United States today is the red imported fire ant. This invasive, foreign ant was brought to the United States from South America by accident in the 1930s. These aggressive, competitive pests continue to spread and now infest about one-fourth of the United States. They damage lawns and create unsightly mounds, but they also attack when disturbed and deliver painful, burning bites to people and pets. Established underground colonies can house hundreds of thousands of fire ants.

Identification: Fire ants are small- to medium-size red and black ants that vary significantly in size. Most other types of ants are fairly consistent in size, but fire ants measure from 1/16 to 1/4 inch in length. Two prominent, bump-like nodes between their thorax and their abdomen distinguish them from other ants.

Signs/Damage: Unless you're unfortunate enough to experience a bite, the first sign of fire ant problems will be a fluffy mound that lacks a central opening. Fire ants prefer sunny locations and sandy soils. Surrounding turf becomes thin and unsightly. If you are bitten, fire ant bites are painful. The bite site produces itchy, burning pustules that can last a week or more.
