Carpenter Ants in SE Louisiana and Mississippi

Carpenter ants are wood-destroying pests and can be confused with termites. In Louisiana and Mississippi, carpenter ants tunnel through support beams and make their way throughout entire buildings. Carpenter ants prefer to nest and excavate water-damaged wood. Unlike termites, carpenter ants do not eat and digest wood. Instead, the ants tunnel and nest through the wood, creating cavities to raise their young. Carpenter ants can severely damage wood, reducing solid structures to hollow shells. If you spot small sawdust piles at ground level or on window sills, you may have a carpenter ant infestation.

Carpenter Ant Habitat

Carpenter ants prefer to live outdoors in damp, decaying wood. Rotting tree stumps, firewood, and wood fencing are all popular habitats. Indoors, carpenter ants infest building materials such as wood or foam insulation. In homes, carpenter ants can occupy cavities like those found in hollow doors or window frames. Although they prefer the outdoors, carpenter ants will make their way inside a building through gaps and cracks in foundations. Workers will also climb through plumbing or electrical openings to gain access to a home.

Carpenter Ant Behaviors, Threats or Dangers

Carpenter ants rarely bite and are not generally thought of as dangerous. The real threat carpenter ants pose, is their ability to damage and weaken the structural integrity of homes and structures.  Colony populations can reach large numbers and over time, nests will split and branch out to form new colonies. 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 dangerous to your home as termites, they can cause serious damage. If a carpenter ant infestation is suspected, it is best to contact a professional ant exterminator.
