This time, however, we were able to effectively combat them with a home remedy. We mixed boric acid & sugar in water and set the concoction in a few little lids across the kitchen. We used roughly a 1:1:1 ratio, but it isn't an exact science. It's also not important if it doesn't dissolve completely.
The idea behind this is that the boric acid will not kill the ants instentaneously. In fact, the sugar will lure ants to it. Also, this amount of boric acid isn't harmful, even to most pets.
I don't have any pictures to do an instructable, so I thought I'd share it here. If someone else does this, feel free to do an instructable. (no credit needed)
