Acrobat ants are known for being able to raise their heart shape end (thorax). They can emit a smell when they are provoked and can bite. They are generally considered harmless. Once inside your home, they can colonize within your walls.

What Do Acrobat Ants Look Like?

Acrobat ants are light brown to black in color. They are relatively small, usually measuring about 1/8” (3.2 mm) in length. Queens, however, are generally larger but can range in size up to 3/8” (10 mm) long. Acrobat ants have a segmented body and when looked down upon, the shape of their abdomen resembles a heart. These ants possess a stinger, and their antennae are 11-segment with a 3-segmented club.

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. Keep an eye out for peeling paint, mold or fungal growth, or deteriorating wood along with soffits and around window frames.
