Ahhhh Ants

[antproblems]

I live near Davis Square, and I've recently realized that I've got a carpenter ant problem - the little jerks came out of nowhere, and now they're exploring all over my apartment. They are not focused on any one area (no trail to follow), and they are concentrated in a few rooms (with crummy windows), so I think the nest may be outside. Any recommendations to go back to an ant-free existence?
Edit to add: I do have a cat, and would prefer not to poison her.

I haven't tried on carpenter ants, but I have always solved ant problems with a borax/sugar/water mixture (like so: http://www.mashupmom.com/yes-borax-got-rid-of-the-ants/). You wouldn't want your cat to eat it, but you ought to be able to set it up in a cardboard box with a small hole cut in the bottom edge, or something like that that she couldn't get into.

This is the advice I was going to give.

Same here. I tried ant traps with no success. Cotton balls soaked in borax/sugar/water got rid of them in just a few days.
