Ants can be an annoying problem as many and they are hard to get rid of permanently without spraying chemical pesticides. This in turn might not be what many people prefer. A cheaper and a healthier solution to this lies in the answers of mother nature.
Cinnamon is a tree bark that has evolved over the years to repel ants. This bark, a common spice, can be powdered or the powder itself can be bought, and sprayed over in the area where the problem is present. You can boil it in hot water before spraying the water instead of powder if you want a more effective solution.
