Query: No effect on the ants in our yard

We have thousands of little black ants in our yard. A couple weeks ago, they started coming into the house, so I ordered some of the Combat Ant Killing Gel, along with the 6 Terro-PCO Liquid Ant Bait Stations to try to wipe out the colony. I put the gel and bait stations along various lines of ants in the yard. They did kill some of the ants that contacted the gel or bait stations, but had no effect on the colony. A week and a half later, we still have a million ants in the yard.
