With Terro Outdoor Liquid Ant Bait Stakes, stop the problem at the source. The stakes target ants outdoors before they can make their way inside. The slow killing poison gives ants time to transport the bait to the colony and the queen, eliminating the ants you see, and the ones you don't. The baits are easy to use - simply place the stakes in outdoor areas where ants have been observed, break the tab open, and let the bait work its magic. A see through bait monitor helps you keep track of when it's time to replace. The stakes are weatherproof, offering protection through all elements.
