1- Use Essential Oils:
When any forager from the ant house goes out to look for food, it essentially marks the path from the nest to the food with the use of pheromone trail.
The worker ants from the nest smell this pheromone to follow the path and get to the food. However, there are certain natural scents that tend to interfere with the trail scent created by ants.
Some of the popular essential oils you can use to get rid of ants include Tea-Tree Oil, Peppermint Oil, Clove Oil, Lemon-Orange Oil, etc.
Place certain drops of these essential oils over the cotton ball. Now wipe it over any possible entry points and corners of the house. Repeat this every other day till you see that the ants are gone completely.
