The answer to 'are ant dangerous' is no, most common household ants are not dangerous to humans. Ants generally do not pose a threat and are more of a nuisance pest that can be managed with proper control methods. While some species of ants, such as fire ants or carpenter ants, can bite or sting, the vast majority of ants found in and around homes are not aggressive and do not cause harm to people.
Ants are social insects that live in colonies and typically forage for food sources like crumbs, spills, or pet food. They can be a problem by contaminating food, damaging property, or causing an unpleasant presence, but they do not generally present a health hazard. Proper sanitation, exclusion, and targeted treatment can effectively control ant infestations in most cases.
