1. you poured too many liquid terro. Most will harden before ants finish them. Pour little at a time, and increase surface area.
2. It will take 2-3 years to finally get rid of ants. However watch out other species of ants may invade
3. Ants build resistance and learn to avoid terro every application. They will remember next year too
4. Apply terro as early as possible as soon as you see the first ant in spring. Way quicker to end colonies.
