well, been through the attic, basement, and all outside. Cant find where they are and don't see any bad timbers anywhere in the house. it doesn't seem as though there are a whole lot of them, killed about 10 or so in last week. Only thing I can think of is the trees behind the house which somewhat over hang the backside of garage. maybe I will be cutting them down.
Bad move. If you cut them down, they may move the colony. That is the one thing the Orkin guy told us. "If you cut them down, call us and we will be on site when they do it. That way if the scatter, they will be dead. They would treat the ground the night before and show up when the tree crew shows up, to make sure that the ants are eradicated."
