Gel baits are a common pesticide application for ants, these baits provide both sugar and a source of water — and ants rarely turn their nose up to this delictible combo. Ants ingest this material, head back home and ever-so-kindly share it with the wife, the kids and all his buddies. He tells other ants about this open bar who, in turn, head out to find it for happy hour. They return to share even more. Then everyone in the ant colony has a bad day. The end.
