I noticed this morning that my old-fashioned orange juicer had about 50 ants inside even though I had washed it after the last use. So I cleaned it up, made myself a nice glass of honey tangerine juice, and left the remains of the tangerine in the cupboard near where they enter, open side up. Now they are swarming into the tangerine -- and in order to get there they have to cross a ring of diatomaceous earth! This bait works incredibly well. In one day I've flung open the cupboard door and thrown that tangerine shell into the kitchen sink, and washed hundreds of ants down the drain with boiling water. The tangerine half is still working tonight and there are far fewer ants elsewhere in the ktichen. Die, you devils, DIE!
