When entering homes, thief ants may be carriers of disease-producing organisms, transmitting pathogens from a food source to human food. Thief ants trail inside cabinets, on walls, baseboards, tree branches, and shrubs. Due to their small size, they are able to forage into packaged foods. If a thief ant infestation is suspected, it is recommended to contact a licensed ant exterminator.
