Carpenter Ants are the largest ant species in North America and can cause significant damage to homes when they reach large popultions. Majority of the damage done by Carpenter Ants occurs in rotted or damaged wood and soft materials such as foam insulation.  Unlike Termites who eat and digest  wood 24/7, Carpenter Ants will make galleries or nesting sites in the wood and discard the debris. This sawdust makes an excellent indicator for Carpenter Ant activity. They are most active during dusk and will often lead you right to the nest. Over the counter products will rarely work on these guys and should NOT be applied if you are having carpenter ant problems.
