Carpenter ants usually show up where wood has stayed damp for a while. Your technician may find activity around crawlspaces, deck framing, wood trim, window frames, or wall voids affected by leaks or excess moisture.
Carpenter ants do not eat wood, but they tunnel through it to create nesting space. If you are seeing large black ants inside the house, especially in the evening, there may be a colony nesting in or near the structure. Left untreated, carpenter ant activity can lead to damage over time, which is why carpenter ant treatment is included in the Basic Shield Plus plan.
