Carpenter ants are nocturnal. They prefer to nest, (called "galleries"), outdoors, in softened wood. These galleries are clean and have a sandpaper appearance. In comparison, termite "galleries" are rough looking. Wood that has been damaged by carpenter ants contain no mud-like material. Wood that has been damaged by termites contain mud-like material.
Workers move fast and often travel in columns. When alarmed they run about erratically while releasing an alarm pheromone (a coconut-like odor), which draws more workers to the site. Over the counter products, while they can kill worker ants, will alert the rest of the colony to danger. This species of ant will come back. Best to call us to bait the queen.
These ants swarm in June and July.
Pavement ants will displace soil around concrete objects such as sidewalks, patios, driveways, curbs, etc. Pavement ants leave trails near plumbing pipes and electrical wires.
Also look for colonies around the foundations of your home, and inspect around logs or large rocks.
