Recently got an ant problem, the big black ones - carpenter ants. Started seeing a week ago in basement and kitchen. On Sunday put out a stuff from home depot called Terro, liquid. It's supposed to kill and take back to the nest to kill the rest. Also put the crystals around the outside of the house. I have baseboard heating so copper pipes run all over the basement and I'm seeing a lot of dead aunts but can kill 10 everytime I go down. The house and foundation is all brick and block with no obvious signs of entry, and the basement is finished. I'm sure there is a nest somewhere, but can't see. Hoping the bait will get them. I know it's drawing them out, but not fast enough for my liking. Any Ideas out there, glad to take some advice.
