Sugar ants are considered harmless. Swarms of sugar ants can be a nuisance, and especially when they locate a reliable source of food inside your home. While they will not cause any structural damage to your house, sugar ants will gnaw through paper, thin plastic or even cardboard to get through to their contents.
Little black ants are common in yards, they nest under rocks, in rotting logs, and under piles of bricks or lumber. Indoors, nests are located in woodwork, wall voids, decaying wood, masonry, and underneath debris. Homeowners should consider working with a licensed pest professional to employ a preventative pest management plan. There are also a few things that can be done around the property to prevent a little black ant infestation.
