Carpenter ants are capable of damaging any wood, yes – solid dry wood as well. Carpenter ant invasion can become devastating when left unchecked as several colonies of carpenter ants can develop multiple satellite nests. Indoor infestations can be tracked by points of entry such as concrete foundations, cracks, electric and telephone wires and pipes. These ants prefer to nest in structural lumber such as in walls, door frames, window frames and even drywall. They prefer wood that has been softened by moisture, mold, rot, decay or other insects. Signs of carpenter ant infestation is the presence of workers inside a building or home. When a carpenter ant infestation is severe, piles of wood shavings can usually be found beneath the nest and crunching noises can be heard in the walls. When large winged ants appear from ceilings, walls and other places a very large infestation is guarantied. To control an infestation properly it is important to contact a pest control professional.
