Fire Ants actually do a couple things. hunt for food, reproduce and cause a lot of problems. In the State of Texas fire ants are causing millions of dollars in damage on their electrical grid. What happens is that the fire ants are attracted to the electricity, you know those big power boxes throughout our neighborhoods. They will build dirt mounds around the box, eventually shortening out the electricity, the power company has to come back out, repair the damage and wait for it to happen all over again.
