  • Antennae: Yes, 12 segmented, no club
  • Region: Eastern United States including all greater Houston service area
  • Threat Risk: Structural damage risk, but no stinger.

NESTING: This ant nests in wood they have excavated. These excavations (galleries) serve as a nursery for the rearing of their offspring. Frequently these galleries are in unsound wood (rotten, moist etc) by they may also excavate sound wood. They don’t consume the wood although the damage can be just as severe. Stumps, hollow logs, utility poles, and fence posts are all subject to attack.

FOODS: This ant will eat most anything people eat when given the opportunity. They will eat other insects, seeds, aphid honeydew, most sweets and meats including: syrup, honey, jelly, sugars, grease, fats and more! They are known to forage in excess of 100 yards from the nest for food.

STRUCTURAL INVASION: This ant does not sting but does possess a rather strong bite with its extra large mandibles. In the Houston area they have been known to nest in hollow doors, window sills, baseboards, boat hulls, unused pipe (and other protected conduits), wooden floors, porches, soffit/fascia and the list goes on!

CONTROL: The nest must be located to eradicate their presence. Because homes in the Houston area are so closely built you may simply have foraging ants in and around your structure while the nest is on someone else’s property. To protect your structure a routine "Maintenance Program" may be required to prevent permanent settlement. This ant may be eliminated on your property over time with a combination of baits and nest eradication.
