The answer to 'fire ant problem' is that fire ants are a common pest that can quickly infest a yard and cause painful stings. Fire ant colonies build large, dome-shaped mounds in the soil, and the worker ants are aggressive and will swarm and sting when their mound is disturbed. Symptoms of a fire ant infestation include seeing the mounds, observing the ants, and experiencing painful stings.
The best solution for a fire ant problem is to treat the mounds with a fire ant-specific insecticide. This can be done as a DIY project, but it's important to follow the product instructions carefully. For larger infestations or difficult-to-treat areas, it's often best to call in a professional pest control technician who can use more effective methods and ensure the problem is fully resolved.
