30 Natural Home Remedies to Get Rid of Ants from Home & Garden
Learn effective natural remedies to control and eliminate ants from your home and garden without harsh chemicals.
Ants are among the world’s most common household and garden pests. These persistent insects can invade kitchens, gardens, patios, and windowsills in search of sugary foods and nesting spots. While commercial insecticides are widely available, many homeowners prefer natural remedies that are eco-friendly, safe for pets and children, and just as effective. Below you’ll find 30 time-tested, practical remedies to help you banish ant infestations for good.
Understanding Ant Behavior
Knowing what attracts ants is the key to successful elimination. Ants are motivated by food (especially sweets and proteins), water, and safe shelter. Their trails, often visible as small lines of marching insects, are reinforced with pheromones to mark the path for others. Targeting these trails and their sources is critical to lasting ant control.
30 Natural Remedies to Eliminate Ants
Here are practical ways to send ants packing using ingredients and techniques you can trust.
1. White Vinegar Solution
Ants loathe the smell of vinegar. Mix equal parts white vinegar and water in a spray bottle, and spray directly on ant trails or points of entry. The scent disrupts their pheromone trails and deters new ants from following. Repeat daily for best results.
2. Baking Soda and Powdered Sugar
Mix equal parts baking soda and powdered sugar and place small amounts in shallow containers near ant activity. The sugar lures the ants, while the baking soda reacts with their digestive system, killing them.
3. Diatomaceous Earth
Food-grade diatomaceous earth (DE) is harmless to humans and pets but deadly to ants. Sprinkle it along baseboards, garden beds, and places where ants are seen. DE works by dehydrating the insects.
4. Borax Ant Bait
Borax (sodium tetraborate) is a natural mineral used in cleaning and as an insecticide. Mix 1/2 tsp borax, 8 tsp sugar, 1 cup warm water, and soak cotton balls with the solution. Place them near ant trails. Ants carry the bait back to the nest, eliminating the colony. Keep away from pets and children.
5. Lemon Juice
Lemons contain citric acid that destroys scent trails and repels ants. Squeeze fresh lemon juice on windowsills, baseboards, and entrances, or mop floors with diluted lemon juice.
6. Peppermint Oil Spray
Peppermint essential oil acts as a potent ant deterrent. Add 10-15 drops to 2 cups of water, shake well, and spray where ants are seen. The strong scent drives ants away and can mask their scent trails.
7. Tea Tree Oil
Like peppermint, tea tree oil is effective for controlling ants. Mix 5-10 drops in 2 cups of water and spray areas of activity, or leave soaked cotton balls where ants are noticed. Keep essential oils out of reach of pets.
8. Coffee Grounds
Used coffee grounds can be sprinkled around gardens, plants, and entry points to repel ants. The strong aroma confuses their trails and deters nesting.
9. Boiling Water
For outdoor nests and anthills, pour boiling water directly into the entrance. This will kill many ants on contact, particularly those near the surface. Multiple treatments may be needed to reach deeper nest levels. Use caution to avoid damaging nearby plants or burning yourself.
10. Chalk or Baby Powder Barrier
Chalk and talcum-based baby powder contain fine particles that ants dislike crossing. Draw chalk lines or sprinkle powder across doorways, windows, and around plants for a safe, dry barrier.
11. Cinnamon
Ground cinnamon, cinnamon oil, or cinnamon sticks are well-known ant repellents. Scatter the powder or place sticks where ants move, or mix cinnamon oil with water and spray in affected areas. The scent interferes with their scent trails.
12. Cornmeal
Cornmeal is appealing to ants but indigestible, so they carry it back to the colony, causing a disruption. Sprinkle cornmeal along ant trails and nests, both indoors and out.
13. Cloves and Clove Oil
Both clove powder and clove essential oil emit potent aromas that ants dislike. Place whole cloves or soak cotton balls with the oil in problem areas to keep ants at bay.
14. Cayenne or Black Pepper
Sprinkle cayenne or black pepper in areas of ant activity, entryways, or nests. The strong, pungent odor masks ant trails and deters further infestation.
15. Salt Water Solution
Dissolve table salt in water to create a salty spray. Apply generously around door frames, windows, and cracks. Salt acts as a natural desiccant, making environments inhospitable for ants.
16. Soap and Water Spray
Mix a few drops of liquid dish soap with water in a spray bottle. Spray ant trails or directly on visible ants. The soapy solution suffocates ants on contact and removes their scent markers.
17. Essential Oils Blend
Combine several essential oils—such as peppermint, clove, and tea tree oils—with water for a boosted ant deterrent spray. Test oils in a small area first to avoid surface staining.
18. Bay Leaves
Ants dislike the smell of bay leaves. Place whole leaves in kitchen cabinets, food storage, and along baseboards to discourage ant exploration.
19. Cucumbers and Citrus Peels
Peels from cucumbers and citrus fruits (such as oranges, lemons, grapefruits) contain bitter substances that repel ants. Scatter fresh peels near entry points and nests, replacing them every few days.
20. Garlic Cloves
Garlic has a powerful aroma that confuses ant navigation. Crush several cloves and place them at ant entryways. Alternatively, make a garlic-water spray.
21. Vinegar & Essential Oil Floor Cleaner
Create a natural mop solution by adding 10 drops of essential oil (peppermint, tea tree, or citrus) to a cup of white vinegar in your mop bucket. Mop all affected areas to disrupt scent trails and repel returning ants.
22. Lemon Eucalyptus Oil
Lemon eucalyptus oil contains natural citronella, a proven insect repellent. Apply oil-soaked cotton balls to entryways or ant trails, and replace weekly. Do not ingest or let pets access these oils.
23. Oil of Lemon Eucalyptus (OLE)
This commercial product is different from lemon eucalyptus essential oil and is classified as a biopesticide by the EPA. Use OLE as directed on the label for powerful ant repelling action in and around the home.
24. Vinegar & Baking Soda Paste
Mix vinegar and baking soda to form a paste. Apply this along cracks, crevices, and baseboards to block off ant entryways and disrupt their scent trails.
25. Sugar & Borax Gelatin Bait
Stir together gelatin, borax, and sugar solution for a protein-rich ant bait. This attracts protein-loving ants and effectively targets colonies.
26. Oatmeal
Like cornmeal, ants will collect dry oats or oatmeal and bring it to their nests, where it is indigestible and disrupts colony survival over time.
27. Soap Bar Barrier
Scatter pieces of freshly cut soap around outdoor ant nests, garden beds, or plant containers. The soap’s fatty acids are unappealing to ants.
28. Herbal Plantings
Certain plants naturally discourage ants. Grow mint, tansy, lavender, rosemary, and marigold near entryways or where ant problems are persistent. These aromatic plants are unappealing nesting spots for ants.
29. Remove Food & Water Sources
- Wipe kitchen counters daily and clean up crumbs and spills immediately.
- Keep food—especially sweets—in airtight containers.
- Fix leaky faucets and avoid leaving pet bowls out for extended periods.
- Empty trash bins and compost regularly.
Prevention is the most reliable long-term strategy for ant control.
30. Physical Barriers & Repairs
- Seal cracks and crevices around doors, windows, and foundations.
- Replace damaged window screens and repair gaps in caulk or mortar.
- Trim plants and shrubs away from the house to reduce nesting sites.

Frequently Asked Questions (FAQs)
Q: Are there any home remedies that kill ants instantly?
A: Pouring boiling water directly onto outdoor ant mounds is one of the fastest ways to kill large numbers of ants instantly, but repeat treatments may be needed for full colony elimination.
Q: Are natural ant remedies safe for pets and children?
A: Most remedies—like vinegar, baking soda, pepper, and essential oil sprays—are generally safe, but avoid using borax, essential oils, and diatomaceous earth in areas accessible to pets and small children, as ingestion or inhalation may be harmful. Always use caution and read labels accordingly.
Q: Why do ants keep returning even after using these remedies?
A: Ants may return if the main nest is not targeted or if new food or water sources are present. Combine elimination with prevention: seal entry points, clean consistently, and apply multiple remedies for stubborn infestations.
Q: What’s the difference between repellents and baits?
A: Repellents (like vinegar, essential oils, and pepper) drive ants away but may not kill them or eliminate the colony. Baits (borax, sugar-gelatin, cornmeal) attract ants to carry a toxic or disruptive agent back to the nest, killing the queen and other ants for longer-term control.
Q: How do I find where ants are coming from?
A: Follow ant trails to their origin, look for small holes, cracks, or gaps near windows and doorways, and search your yard for anthills or nest sites close to your house’s foundation.
