We had no idea that we had carpenter ants until a leak from one of the pipes about the cabinets required us to look into the wall. There were these little piles of what looked like small grape seeds that were in fact small pieces of wood. We called Freedom Pest Control and they were there the next day diagnosing the situation and installing bait for the problem. We are now signed up with their Gold Protection Plan with Quarterly Services and are comfortable knowing that they will be taken care of. Even if you don't think that you have pests I would highly recommend giving Freedom Pest Control a call to be sure.
