2. Cinnamon
Like the vinegar mentioned above, cinnamon and cinnamon oil serve to deter ants by interfering with their traces of pheromones. Distribute cinnamon in any of its forms throughout areas with ants. When cinnamon is used around window windowsills, plinths, near doors and countertops, it helps prevent ants from entering the house.
Place cinnamon and cloves at the entrance of the house and in areas where you think ants can enter. This is a good method to keep your house smelling fresh and natural. Cinnamon is often seen as an effective option for controlling ants at home. For more effective results, a little essential oil can be added to the cinnamon powder, so that a stronger odor is ingested, retaining the ants.
