Q. I found a small pile of sawdust under an upholstered chair in my studio apartment and figured I have carpenter ants. I don’t know how they got in the chair, since I’ve owned it for at least 10 years and my building is a brick high-rise in the city. Anyway, I placed Raid Ant Baits under the chair where I saw the sawdust. If this doesn’t work, what I could do?
