Home Remedies for Ants
Some of the most successful and reliable home remedies for getting rid of ants are listed below:
You can pour a kettle of boiling water directly onto the ant hills to protect your home.
This can be useful to save your plants and trees. Wrap the tape around the trunk with the sticky side outwardly. It will stick all the ants, and they will either die or be unable to move and fall prey to other bugs.
Garlic, Onion and Pepper Mix
Let a mixture of 1 quart of water, 1 tablespoon of cayenne pepper, 1 onion, and 1 garlic clove sit for an hour. Then, mix in liquid dish-washing soap. Your homemade spray is ready.
Use one tablespoon to sprinkle over the ant mounds. They have a very powerful effect and force the ants to abandon their mounds.
This is the safest remedy to keep ants away. Make a line, a circle or any shape to prevent them from crossing the designated area of salt.
Jelly Mixed with Borax
Mix jelly with borax in equal measurements. Keep this in the area where you know ants will likely come. Be sure to keep this in a place that is inaccessible to children.
Cucumber peel can be used as an excellent ant repellent. Put them in the areas affected by ants and you will notice that they will disappear in no time.
Plantation of Mints
You can grow mint trees like catmint, peppermint, and spearmint that encircle your home. The smell of mint disrupts the smelling capabilities of ants. Without their sense of smell, they will be unable to detect and find the food source and will look elsewhere.
Vinegar, like apple vinegar or normal white vinegar, can be efficient in killing ants. Due to its fungicidal and insecticidal properties, vinegar helps in eradicating ants.
Glass Cleaner with Liquid Dish Wash Soap
An equal mixture of both can be sprayed on the ant-affected areas of your house. Keep in mind that it must not be sprayed on surfaces that can be damaged through the use of soaps or ammonia.
Simply sprinkle the dried mint at the doors, entryways and garbage areas to get rid of ants.
Mint Oil Spray
The essential oil of mint is also found in the mint aroma. This is easily available in most markets. Just get it and spray the area where ants commonly come, and it will act as a serious deterrent.
You can sprinkle tartar cream, chili powder, powdered chalk, powdered cleanser, talcum powder and cinnamon thoroughly in affected areas. Ants can never enter these areas since the smell is so powerful.
This paste is made from 1/3 cup of molasses, 6 tablespoons of sugar (granulated), and 6 tablespoons of active and dry yeast. Stir until they become smooth and nicely blended. Place the mixture in very small portions where ants are frequently found.
Borax is basically a type of laundry detergent, which also contains an unrefined form of boric acid. Borax can serve as a stomach poison as well. Mix 20 borax of mule team type along with sugar water. Ants will carry the borax to their nest and this will kill them and affect the other ants as well.
Thus, by applying these home remedies, you can actually attain some long-lasting relief from annoying ant infestations.

What is an ant?
Ants are insects that live in large groups called colonies, typically found underground.
