I hate carpenter ants even more than I hate the little red ants.
Yesterday I got a bunch of Terro ant traps and deployed them strategically (translation: all over the damn kitchen, laundry room, and pantry) and only spilled the contents of two

This morning there were ants poking around the openings and hopefully calling for their ant buddies to come sample the free chow.
I also cleaned the countertops and backsplash really really really well with good ol' ammonia formula Windex. I wanted to use cleaner with bleach but the damn cats wouldn't get out of the way.
