Characteristics
- 
Size: Ranges from 1/8-inch to more than
1/4-inch in length. The most commonly encountered
species are found at the smaller end of this size
scale.
Color: Ranges from black to
dark brown to red and black. The smaller species
are typically uniformly dark in color. A larger
species, common in Texas, is red and black.
Acrobat ants are identifiable by the heart shape
of their abdomen when viewed from above.
Behavior –
When excited or disturbed, the acrobat ant workers
run about with their abdomens held high above
their heads. Like most ants, acrobat ants establish
well-defined trails between the nest and food
and water sources. They feed on a wide variety
of foods, but the workers are partial to the sweet
honeydew produced by aphids, scales and mealybugs
found feeding on many trees and plants. Fruit
trees, roses and many shrubs serve as hosts for
aphids and may contribute to ant infestations
in buildings. Most infestations inside are the
result of workers searching for food.
Habitat –
Acrobat ants are like carpenter ants in that they
prefer to nest in moist or rotted wood. Colonies
are most often found in tree holes, dead limbs,
stumps and logs. Rotting areas in fences, decks
and railings may also be nesting locations. Most
infestations of acrobat ants originate from outdoor
nests; however, if moist or rotted wood exists
inside because of water leaks, this ant will readily
nest indoors. Such interior nests are typically
found around the perimeter -- in soffits, door
frames and skylights.
Tips for Control
– Acrobat ants are controlled by finding
and treating wood where the ant colonies are located.
Often, the nest may be located far above the ground
in a tree where it is inaccessible to direct treatment.
In such cases, limiting interior invasion of ant
trails is critical. Repairing water leaks and
drying out moist wood inside will help prevent
infestations of both acrobat and carpenter ants.
Improving attic and crawl space ventilation is
also important in limiting acrobat ant infestations.
General tips for limiting ant infestations
include:
- Eliminating piles of lumber, bricks or
other debris that could serve as a nesting
site for ants.
- Keeping landscape mulch less than 2 inches
thick and at least 12 inches away from foundations.
- Ensuring the sprinkler system does not
spray directly onto the foundation.
- Sealing as many cracks in the building's
exterior as possible.
- Keeping tree and shrub branches trimmed
to prevent them from touching the building.
