Moisture Ants aid in the deterioration of water-damaged wood. Evidence of this invader is usually not found until the late summer when the reproductive alates swarm into living spaces, or a wall is opened for construction. Moisture Ant colonies can number in the thousands, and are often started by a single inseminated queen. In ideal conditions, colonies can survive for over 20 years, making them a long-term threat to a structure.
Moisture Ants can only infest heavily saturated wood, and have a primary diet of fungus caused by wood rot and decay. They speed up the decomposition of rotting wood by building elaborate three-dimensional mud tubes (similar in appearance to a sea sponge) which help retain and transfer moisture.
