I have been seeing big black ants in and around my home. What are they and can they do damage to my home?

These are most likely carpenter ants and while not as voracious as termites they are classified as a wood-destroying insects. They will often times chew the wood to make hollow “galleries” in their efforts to establish a suitable nesting site. They are often found in areas of the structure where moisture exists, as this wood is much easier for them to attack.
