Ants hate strong smells. Cinnamon, cayenne pepper, coffee grounds, and mint. Sprinkle these around doorways, along cracks, and near the nest.
It won’t kill them, but it’ll confuse their navigation. Imagine trying to find the grocery store if someone replaced all the road signs with strong smells of bacon. That’s what it’s like for an ant.
You’ll need to reapply after rain. But hey, your yard will smell amazing. It’s a win-win.

Chemical warfare: Last resort, but fine
Look, sometimes the natural stuff fails. If the ants are laughing at your cinnamon and your boiling water, get a granular insecticide labeled for fire ants and lawn ants.
Spread it according to the instructions (yes, read them). Water it in lightly. This stuff kills the colony for weeks. It’s nuclear, but effective.
Just keep kids and pets off the treated area until it dries. You’re evicting ants, not creating a Superfund site.
