When structural damage becomes apparent – it usually is the result of years of infestation.
Most damage is in basements and foundation timber just above the foundation walls.
Outside, it is important to inspect wooden posts, steps, trellises and other structures that are close to the ground for rot and damage. Wood piles stacked near your home often lead pests such as carpenter ants and termites, and should be moved away from the building.
A leaking roof or a blocked gutter can cause excess moisture in wood and in the ground next to your foundation which attracts carpenter ants and termites.
Ants are particularly busy in the spring when they are looking for food and new nesting sites.
