Carpenter ants are one of those infestations that you do not want to mess with. Over time, it is amazing how much damage they can, structurally, do to a home. We lived in a cedar, log home and we tried, unsuccessfully,for two years, to rid them from our home. It started out with a sporadic 20 or so, over the course of a month or two. Then... one year, BAM... it was out of control! As much as I didn't want to do it, we had to have professionals come out (I believe it was Orkin) and they had to bore small (in diameter) holes in strategic high places and shoot this gooey substance inside. Then they sprayed the very base of my foundation. The contract that you have with the professional should also include "yearly maintenance" and, many times, that can be passed along if you choose to ever sell. I can't remember all the details but there were several trips they made for the first year, to make sure they hit all the hot spots.
The baby, tiny red or black ants are a nuisance and will come and go, seasonally. Those can be controlled with different household items (i.e. vinegar, borax, bay leaves in cabinets, etc.....). Spraying along your foundation is good. However, once you have a "few" carpenter ants, expect that number to grow over the years. They are just as savage as termintes - not what you wanted to hear but you won't want to have to go through the trouble of doing costly repairs on your home, either. It doesn't matter if you have a frame or brick home - all homes, still, have lot's of wood.
Good luck.
