Dish soap
Mix 7 drops of dish soap with 1/4 cup water and spray on areas where ants appear frequently (like kitchen counters). This will help kill off existing colonies and prevent new ones from forming in these areas.
Cinnamon
Cinnamon is great for repelling ants because it is a strong scent that will keep them from entering your home. You can sprinkle cinnamon on the ground around your house or on the window sills and doorways to keep them away.
If you want to be more thorough about it, you can sprinkle cinnamon into cracks and crevices where ants might be coming into your house.
Cornmeal
Cornmeal is another natural repellent that works well against ants. You can use cornmeal around windowsills, doorways, and other areas where you have noticed ants entering your home.
You should also use cornmeal around plants that you want to be protected from pests like slugs or snails. The cornmeal will help keep those pests away as well as prevent ants from getting into your garden area.
