Signs of Infestation
Carpenter ants do not actually eat wood, but they do cause damage to wooden structures by excavating tunnels to build their nests. The extent of the damage varies and is usually dependent on how long colonies have existed in homes. Individuals can typically tell when carpenter ant infestations are present from the appearance of sawdust, dead ants, and the remains of other insect species carpenter ants feed on around infested wood. Areas of high moisture in the home foster weakened wood support beams and foundations, which serve as ideal points of entry for the pests.
Most carpenter ant damage is not externally visible, which makes it hard to detect. As ant colonies grow, the amount of destruction becomes more noticeable and immediate action should be taken. Carpenter ants tend to infest moist wood in and around bathtubs, sinks, dishwashers, and under roofs. Replacing areas damaged by water helps circumvent future infestations and avoid structural issues. For large populations of the pest, homeowners should contact trained pest professionals to remove carpenter ants and set up plans to help prevent future damage.
