    What Do Acrobat Ants Look Like?

    Acrobat ants are light brown to black in color. They are relatively small, their abdomen is the shape which resembles a heart. These ants possess a stinger.

    Signs of an Infestation

    The most obvious sign of an acrobat ant infestation is the presence of actual ant trails on wires, utility lines and pipes coming into walls. Acrobat ants will occasionally forage up to 100 feet away from their nest for resources, so you might spot them trailing along the foundation in search of food. Additionally, debris such as dirt and wood scraps that acrobat ants deposit as they excavate their nests can serve as another telltale sign of an infestation. If the home has siding, look for pieces of foam insulation, which could indicate an acrobat ant nest behind the siding.

    Homeowners should also check for moisture damage around the structure of the home, which could attract acrobat ants, carpenter ants and other wood-nesting pests like termites. We are happy to inspect your crawlspace for peeling paint, mold or fungal growth, or deteriorating wood along soffits and around window frames.

    Acrobat Ants Prevention

    There are many techniques that can be used to prevent acrobat ants. First and foremost, it’s important to keep a close eye on the exterior of the home for visible signs of an acrobat ant infestation as described above. PMi provides quarterly service that keeps an eye on areas for possible infestations.

    Keep all food, including pet food, stored in sealed plastic or glass containers.

    How to Get Rid of Acrobat Ants

    If you suspect an acrobat ant infestation in your home, contact PMi to conduct an interior and exterior inspection and work with you to develop an acrobat ant treatment plan. We may inquire about past water leaks, plumbing problems, etc., which could indicate an acrobat ant infestation. In the yard, we will likely check logs, stumps, firewood, tree cavities and loose bark for ant nests. Once the ant species is properly identified, the appropriate control measures can be taken.



    Outside, most species of acrobat ants nest under rocks or in logs, firewood and trees where wood decay allows them to create tunnels. They also build their nests in abandoned cavities carved out by other insects such as termites and carpenter ants.
