The answer to 'fire ant trails' is that fire ant trails are a common sign of an active fire ant infestation. Fire ants build intricate underground nests and create visible trails as they forage for food above ground. These trails are often found near the mound entrance or leading to a food source.
Fire ant trails can be a nuisance and indicate a larger problem that may require professional treatment. While some DIY methods can help, it's often best to call a pest control expert to properly identify and eliminate the fire ant colony.
