Carpenter Ants in Knoxville TN

Often confused with termites, carpenter ants are wood-destroying pests. In the Knoxville area, these ants burrow through wood and wooden beams as they construct nests, destroying the structural integrity of homes and businesses. Carpenter ants do not eat and digest wood, but instead, bore through the wood to create cavities to raise their young. Over time, they seriously damage wood, reducing solid structures to hollow shells. Seeing ants crawling out of holes or crevices in structures or hearing faint rustling noises in walls are both indications of a carpenter ant infestation.

Carpenter Ant Habitat

Drawn to moisture, carpenter ants prefer to build nests in damp, decaying wood. They feed on a variety of foods but prefer the sugary honeydew excreted by plant-sucking insects. Colonies of carpenter ants access homes through cracks around doors and windows, gaps, wires, or straight through wet, damaged wood. In homes and businesses, carpenter ants infest construction materials such as foam insulation or wood. Carpenter ants will infest any area in a structure where wood and water come together, producing rotting wood. Indoor carpenter ant infestations are always associated with moisture issues in homes or businesses.

Carpenter Ant Behaviors, Threats or Dangers

Even though carpenter ants rarely bite and are not generally thought of as dangerous, they pose a serious threat to homeowners. Their burrowing activity weakens and destroys the structural integrity of homes and businesses. Carpenter ants swarm in order to mate and establish new colonies. Seeing winged, flying ants in your home is a sign of an infestation. While carpenter ants are not as destructive as termites, if left unchecked, they systematically destroy homes and valuable wood objects within them. If a carpenter ant infestation is suspected, it is best to contact a professional ant exterminator.
