Ghost ants are highly adaptable in their nesting habits, which seem to be similar to those of pharaoh ants. Colonies of ghost ants are moderate to large in size and can contain thousands of workers and numerous functional queens distributed across multiple nesting sites.
Outside, ghost ants make their nest in the ground. They prefer cavities and crevices in dead tree branches, but will also nest under stones, inside logs and within piles of leaves and other debris. Ghost ants will readily enter structures by trailing from nests along sidewalks, patios and foundation walls. Inside, ghost ants typically nest in wall voids, behind baseboards, between cabinets and inside the soil of potted plants. Because of their high moisture needs, ghost ants can also be found trailing to water sources such as sinks, shower stalls and tubs.
Ghost ants do not sting, as they lack a stinger. However, ghost ants can become a serious nuisance because they are known to nest inside homes.
