Terro can be found in hardware stores around here. It's a little bottle of clear syrup-like stuff (boric acid). the ants can NOT resist it. For a day or two you will need to keep replenishing the supply and be appalled at all the ants, but they are coming to take the poison back to their friends in the nest. They all die very soon!

yes... Terro is the best...I also am amazed with the product Diotomatious Earth... a all natural product...

I guess it's a good thing you got an inspection! lol

Whoever said they dont nest in houses is DEAD wrong, we dont have termites up in our area but let me tell you as a contractor that carpenter ants are destructive, Carpenter ants differ from termites, which use wood as a food source and will eat sound wood. Carpenter ants do not eat wood; they nest in wet or water-damaged wood. Sometimes they find a void to serve as a nesting area. Keeping wood piles away from your foundation and any wood siding etc from direct contact to soil will help.

My primary residence had been neglected for years when I bought it with a leaking back addition and when I tore in for remodeling, the carpenter ants had destroyed everything. After rectifying why they were originally there, I started treating with an outside pest granules that worked great, problem is a year or so later the main ingredient that made them work so well was outlawed ( diazinon ) after that, every spring I started the battle all over again when the warm weather would come the huge black critters would appear. I tried the taro and etc traps, but nothing worked that well because what you need to do is kill the nest each time, not the individual ants. After many trials and endless searches, I found one that worked and worked GREAT. Take GRAPE jelly ( only Grape for whatever reason ) and mix in a small amount of the powder boric acid ( safe and available everywhere including dollar stores, drug stores, home centers etc ) put small amounts of it out on disposable plastic lid containers or such and place them in your home where you see the most ants. Here is another REALLY important part, if when you examine those areas you see dead ants around it, do NOT remove them, leave them as the other ants will carry them back to the nest, the object is for the ants to not only eat the poison, but make it back to the nest to poison the others. You will need to dispose of your jelly traps regularly as it can mold if left too long.

Some areas are just prone to them and while the avoidance tips I gave, helps, in my instance I just had this jelly ritual every year before they started showing up and never had another problem.
