Ants are one of the most common pests homeowners deal with, often invading kitchens, bathrooms, and outdoor spaces in search of food and moisture. Although professional pest management offers the most reliable and long-lasting results, there are several natural remedies that can help reduce ant activity as a first step.
These do-it-yourself methods may help limit the presence of ants temporarily, but it’s important to remember that most home remedies won’t eliminate the colony at its source. Still, they can provide short-term relief and complement a professional pest control plan.
Natural Remedies for Ant Prevention and Control
1. Vinegar Spray
White vinegar is one of the simplest natural solutions for deterring ants. Mix equal parts vinegar and water in a spray bottle and apply it to windowsills, countertops, and along visible trails. The acidic scent interferes with the pheromone trails ants use to navigate, discouraging them from returning.
2. Lemon Juice
Like vinegar, lemon juice disrupts ant scent trails with its acidity. Squeeze fresh lemon juice around door frames, floor edges, and cracks to create a natural barrier. You can also dilute lemon juice with water to make a gentle, citrus-scented repellent spray.
3. Sugar and Baking Soda Mixture
This simple home remedy targets ants directly. Combine equal parts baking soda and sugar, then place small amounts near ant trails or suspected nesting sites. The sugar attracts the ants, while the baking soda interferes with their digestion once consumed.
4. Diatomaceous Earth
Food-grade diatomaceous earth is a natural powder that kills ants through dehydration. Sprinkle a light layer in areas where you’ve seen ant activity, such as behind appliances, under sinks, or along baseboards. Always choose food-grade DE, which is non-toxic to humans and pets.
5. Essential Oils
Essential oils, particularly peppermint, tea tree, and eucalyptus, can help repel ants naturally. Add several drops to a spray bottle of water and apply the mixture around entry points. These oils have strong scents that ants avoid and are often used as a complementary prevention method.
6. Cinnamon
Cinnamon is more than a kitchen spice, it can also be used as a mild ant deterrent. Sprinkle ground cinnamon or place cinnamon sticks near windows, doors, and cracks. Its distinct scent masks the pheromone trails ants rely on to communicate.
7. Borax and Sugar Bait
Borax is a naturally occurring mineral that’s commonly used to control ants. Mix borax with sugar and a small amount of water to form a paste, then set it out in shallow containers near active areas. The ants carry it back to the colony, which can help eliminate larger infestations. Always use caution when applying borax in homes, as it can be dangerous near children or pets.
8. Coffee Grounds
Used coffee grounds can be spread around the perimeter of your home or garden beds to help deter ants. Their strong scent masks attractant odors and discourages ants from nesting nearby.
9. Cornmeal
Cornmeal is another natural option. Ants often take cornmeal back to their nests, but they’re unable to digest it properly, which can reduce their population over time.
10. Dish Soap and Water
A quick and inexpensive way to manage visible ants is with soapy water. Mix a few drops of dish soap into a spray bottle filled with water and spray directly on ant trails or groups. The soap breaks down their outer layer, killing them on contact.
11. Clove Oil
Clove essential oil is known for its powerful scent and ant-repelling properties. Mix several drops with water and spray it into cracks, corners, and wall gaps where ants may be entering.
12. Chalk Barrier
Drawing a line of chalk across entry points can disrupt the ants’ scent trails, making it harder for them to navigate. While this isn’t a long-term fix, it can help minimize ant activity temporarily.
13. Ant-Repelling Plants
Certain plants naturally repel ants due to their strong aromas. Planting herbs like mint, basil, or lavender near entry points and outdoor patios can help discourage ants from settling close to your home.
When Natural Remedies Aren’t Enough
Natural ant control methods can help reduce visible activity, but they rarely address the colony itself. Ants often nest deep within walls, foundations, or soil, making complete removal difficult without professional treatment.
