1. Lemons
Lemon juice can be used topically or sprayed on surfaces to repel ants by eradicating pheromone trails and concealing the aroma of food. Lemon rinds in your cabinet may help discourage ants from setting up shop in your kitchen.
2. Neem oil
Neem oil is advised for use around plants by gardeners, particularly in areas where ants or aphids are present. Neem oil can be used to kill aphids, which are tiny sap-sucking insects that are raised by ants, thus eliminating both types of pests. Diluted neem and products containing neem extract do not function nearly as well as full-strength neem oil.
3. Cornstarch
Cornstarch, which is accessible in grocery stores, can be a useful tool for smothering numerous ants simultaneously. The procedure is to liberally sprinkle cornstarch and water over the entire colony of ants. You can then clear up the countless dead ants that are then covered in cornstarch as a result.
4. Boiling water
Pour hot water into any ant holes you see close to your house. Many of the ants within will be efficiently and instantly killed by this technique. Even though anthills have a tiny appearance, they conceal enormous ant colonies.
5. White Vinegar
An inexpensive and efficient method to kill and repel ants is to use white vinegar, which is sold in all grocery stores. It functions as a natural cleaner as well. Wherever ants are prone to go, try cleaning hard surfaces with a 1-to-1 vinegar/water solution, including floors and countertops. Spray the mixture on any ants you observe or remove them with a paper towel.
6. Tea tree oil
An efficient ant repellent is tea tree oil. Follow these steps to apply this technique. In a clean plastic spray container, combine 2 cups of water and 5 to 10 drops of tea tree essential oil. Wherever you frequently find ants in the house, spray the mixture there. As an alternative, you can spread cotton balls around your house after soaking them in the mixture.
7. Coffee grounds
Ants can be repelled by coffee grounds that have been brewed. Consider leaving the freshly brewed coffee grinds on disposable surfaces (like index cards) in pet bowls and other gathering places for ants.
