Carpenter ants are the largest ants found in attics. Because they’re a wood-destroying organism (WDO), it’s important to find the nest quickly.
Carpenter ants gain access via overhanging tree limbs or electrical service wiring. Damp, rotting wood is common near weathered roofing cement, vent pipes, flashing around chimneys, skylights, and roof penetrations. Ants move in and hollow out trusses, joists, rafters and fascia boards to create galleries.
With a constant supply of water and easy access to food, ant colonies flourish and damage can be extensive. Carefully inspect these areas, and treat with residual dusts or baits according to the label.
