The answer to 'why is my fire ant damage' is that fire ants are an aggressive, invasive species that can quickly build large, destructive colonies in your yard. They cause damage by building mounds that can destroy lawn and landscaping, and their painful stings can be a serious threat to people and pets.
Fire ants are attracted to warm, moist soil and thrive in the southern United States. Their colonies can grow to hundreds of thousands of ants and spread rapidly, quickly taking over a yard or garden. The mounds they build can be several feet wide and several inches tall, smothering and killing grass, plants, and flowers. Their stings also pose a health risk, as they can trigger allergic reactions in some people.
