Ant infestations pose several health risks that necessitate professional extermination. Certain species, like fire ants, can deliver painful stings that cause allergic reactions in some individuals. Carpenter ants can compromise the structural integrity of buildings by burrowing into wood. Additionally, ants can contaminate food sources and spread bacteria, leading to potential foodborne illnesses. Some species are known to carry pathogens like Salmonella and E. coli. Professional exterminators not only eliminate these pests but also provide advice on maintaining a clean and sanitary environment, thereby reducing the risk of health issues associated with ant infestations.
