J.M.
Just saw your request. We had ants TERRIBLE two winter's ago. Just as we were bringing home our new son from the hospital. I guess they were coming in from the outside because it was getting so cold. They were parading around our house. We'd have people over to see the baby and here would come an ant toodling across our living room. It was so bad we had to have a dust/spray injected inside the walls of our house. We used Ant Eater Pest Control - I believe they are all over, but we use the one out of Birmingham. They do a great job and are very friendly and knowledgeable. However, to really get rid of the ants, if they are bad, you will need to do several applications. Sorry, don't have the #.
