The answer to 'fire ant in my house' is that fire ants are an invasive pest that can quickly establish colonies indoors. Fire ants are aggressive and their painful stings can be a serious issue for homeowners. The most common causes of fire ants indoors are that they have built a nest nearby and are foraging for food, or they have found a way to enter the home through cracks, crevices, or openings.
Symptoms of a fire ant infestation include seeing the ants themselves, finding piles of dirt or debris that indicate a nest, and experiencing painful stings, especially if the nest is disturbed. To solve the problem, you'll need to locate and eliminate the nest, then seal any entry points to prevent them from returning. For small infestations, DIY treatment with approved baits or insecticides may be effective, but for larger or persistent issues, it's best to call in a professional pest control expert.
