What is a Ghost Ant?
Ghost Ants are highly adaptable and can nest both indoors and outdoors. Outdoors, they prefer moist environments such as under stones, logs, or within plant stems. Indoors, they are commonly found in wall voids, behind baseboards, and near moisture sources like sinks and potted plants. They are also considered “transient ants,” meaning they do not build permanent nests but instead move their colonies frequently to access food and moisture. Their colonies are polygynous, containing multiple queens, which allows them to expand rapidly and form large infestations.
What Do Ghost Ants Look Like?
Ghost Ants are among the smallest household ants, with workers measuring just over 1 mm in length. They have a distinctive coloration: a dark brown head and thorax contrasted by a milky white gaster and legs. This unique appearance makes them difficult to detect, especially on light surfaces. Their antennae have 12 segments that gradually thicken towards the tip, and they lack a stinger.

Management of Ghost Ants
Ghost Ants can be especially challenging to control due to their small size, nesting habits, and ability to quickly relocate colonies. Because they often nest in wall voids or other hidden areas, over-the-counter sprays may only eliminate the visible workers, not the source of the infestation.
At Wise House Pest Control, we use a comprehensive approach that includes:
- Careful inspection to locate nests and entry points
- Use of non-repellent baits that workers carry back to the colony
- Low-toxicity treatments that are safe for families and pets
- Long-term prevention strategies that address moisture and access
Professional treatment is often necessary for full eradication, especially in large or recurring infestations.
