Let’s be clear: pepper doesn’t kill ants, but its strong smell does scare them away. Pour the ground version of black or cayenne pepper over the ants’ scent trails. You can also mix pepper and water in a spray bottle and sprinkle it over the entry points to your home.
Cinnamon

The best spice for getting rid of ants in the kitchen? Cinnamon. Natural and non-toxic, cinnamon not only kills ants, but its strong scent also makes it a repellent of choice.
Fresh mint

Ants don’t like the smell of fresh mint, so we recommend planting it in vegetable and flower beds.
