When I was a kid my dad would make ant baits out of boric acid and honey, keeping them out of reach of the dog and being very clear with my brother and I that this was poison. I did the same in an apartment a few years ago to take care of an ant problem, and it worked great. About 2 parts honey to 1 part boric acid powder, I think?
