We have talked about dealing with termites, lizards and mosquitoes at home, so now, here are some natural ways to combat ants.

1. Peppermint essential oil

Ants often leave a pheromone trail wherever they go, and send out different smell signals to alert other ants of when food is nearby or when there is danger ahead. Mask the smell that ants leave with a strong essential oil like peppermint. 

2. Vinegar

Just like the smell of strong essential oils, vinegar masks the scent of pheromones that ants give out. Make a vinegar spray by filling a spray bottle with equal parts water and white vinegar, and spray on affected areas and ant entry points.

3. Citrus peel spray

If you can't stand the smell of vinegar and hate the oily residue that essential oils can leave, try a citrus peel spray. Simply soak some lemon, orange or lime peels in water and heat up. Afterwards, drain and keep the citrus-infused liquid. Let it cool and keep in a spray bottle.

4. Chalk

Ants apparently hate walking on powdery materials like chalk because they contain calcium carbonate. Once again, it masks the scent left by other ants and completely numbs their ability to sense and feel their surroundings.

5. Cayenne pepper

Cayenne pepper works more like a deterrent than a poison for ants. Simply mix some cayenne pepper with water and spray on affected areas. Ants hate the strong and spicy scent that it leaves.
