The answer to 'how did fire ants get in my house' is that fire ants can enter homes through small cracks and openings, such as around utility pipes, doors, and windows. They may also be accidentally brought inside in potted plants, boxes, or other items. Fire ants are very persistent and can build nests both indoors and outdoors, posing a serious threat to homeowners.
Once fire ants have established a presence in your home, you may notice them foraging for food, building mounds, or swarming if their nest is disturbed. They can also cause painful stings that can be dangerous for some people. Dealing with a fire ant infestation requires prompt action to eliminate the colony and prevent future infestations.
