Ants
Appearance
Acrobat ants (Crematogaster spp.) get their name from their habit of acrobatically raising their abdomen above their head, especially when they are disturbed. When viewed from above, the abdomen is heart-shaped. There are several species of acrobat ants in the United States. Acrobat ants are small; most species are less than 5.4 mm in length. Many emit an unpleasant odor when disturbed.
Behavior, Diet & Habits
Outdoors, acrobat ants nest near moisture such as under stones, in stumps, in rotting logs and under woodpiles. When they invade homes, acrobat ants often nest in damp areas such as in foam sheathing behind siding, and they even have been found nesting in roofing near a leaking skylight.
Acrobat ants often nest in wood that termites or carpenter ants have damaged. It is common for acrobat ants to clean out the galleries that other insects have made in the wood. They push the dirt or wood scraps out of the galleries. Sometimes homeowners find this debris and think there is an active termite infestation.
Acrobat ants normally eat insects and honeydew, a sugary waste excreted by sap-feeding insects like aphids. Acrobat ants protect the aphids that produce the honeydew. If acrobat ants come into a home, they usually prefer sweets and meat.
The acrobat ant workers enter homes in several ways. Sometimes they make a trail across the ground. Door thresholds and construction gaps are common entryways. Workers can also follow tree limbs or shrubs that touch the house. They have even made their trails on utility lines. The ants can enter the home through the same opening that pipes or wires go through.
