Ants are one of the most common household pests that can quickly become a nuisance. When ants invade your home in large numbers, it can be incredibly frustrating trying to get rid of them. While chemical pesticides may seem like the easiest option, they come with health and environmental risks. The good news is there are many safe, natural ways to get ants under control without using dangerous chemicals. This guide will provide DIY methods to repel ants, eliminate existing colonies, and prevent future infestations using natural ingredients you likely already have at home. With a few simple steps, you can send ants packing and enjoy a pest-free home.
I. Introduction
Ants are resilient little creatures that can find their way into even the cleanest households. Once inside, they forage for food, creating long trails between their nest and food source. Ants thrive in moist environments and are attracted to sweets and proteins. If they discover a prime food source in your home, ants will quickly return in droves.
Having ants infiltrating your home is more than just a nuisance. They can contaminate food, spread bacteria, and even cause structural damage if a colony goes undetected. Getting rid of ants using natural, non-toxic methods is the safest and most effective approach, especially if you have children or pets. The natural repellents and baits recommended in this guide will eliminate existing ant colonies and keep new ones from forming without endangering your family or the environment.
II. Understanding Ant Behavior
Knowing some basics about ant behavior will help you pinpoint how they are getting into your house and where their nests may be located. There are hundreds of ant species, but a few common household offenders are:
- Argentine ants – Light brownish ants that like sweet foods and nest outdoors. They come indoors looking for food and water.
- Carpenter ants – Large black ants that excavate dry, damaged wood to form nest galleries. They come indoors for food and water.
- Odorous house ants – Small black ants with a strong odor when crushed. They nest outdoors but forage indoors for sweets and protein.
- Pavement ants – Black or reddish ants that nest outdoors, especially under stones. They follow scent trails inside in search of food.
- Pharaoh ants – Tiny yellow or light brown ants that thrive in warm, moist environments indoors. They forage for protein and sweet foods.
- Thief ants – Very small ants that nest indoors close to food sources, such as in kitchens or pantries. They prefer greasy and sweet foods.
Ants communicate using pheromones, following scent trails laid down by scout ants from the colony to food sources. If you see a long line of ants marching into your kitchen, they are likely following one of these trails from an outdoor nest to your home.
Eliminating this scent trail and food source is key to getting rid of the ants. Ants enter homes through the tiniest crevices and gaps, so sealing entry points is also vital for evicting ants and keeping them out.
III. Natural Ant Repellents
One of the easiest ways to discourage ants and get rid of existing trails or colonies is by using natural ant repellents. Common household items like vinegar, citrus peels, spices, chalk, and essential oils all effectively repel ants without using harsh chemicals. These affordable home ingredients overpower the scent trails ants rely on, disguising food sources and causing ants to flee.
Use Vinegar
Vinegar contains acetic acid which ants find toxic and strongly avoid. A simple vinegar-water solution can be used to wipe down countertops, cabinets, and other surfaces to erase ant trails and repel ants:
- Mix equal parts white vinegar and water in a spray bottle
- Lightly spray areas where you see ants congregating
- Wipe down surfaces to erase lingering ant pheromones
You can also place shallow dishes of vinegar around outdoor ant nests or entry points. The vinegar smell deters the ants from returning. Just replace the vinegar every few days when it starts to evaporate.
Try Citrus Peels
The strong citrus scent from orange, lemon, lime and grapefruit peels is abhorrent to ants. Cut up citrus fruits into pieces and place the peels around indoor and outdoor ant paths. Or simmer citrus peels in water to make a concentrated citrus oil and wipe surfaces with the solution. The ants will avoid these areas.
Sprinkle Spices and Chalk
Ground cinnamon, cayenne pepper, black pepper and cloves can be sprinkled liberally along ant trails, entry points and around outdoor nests. Chalk lines provide a barrier ants will not cross, so draw lines near ant trails or around door frames and windows to keep them out. These spices and chalk overwhelm the pheromones, confusing the ants so they can’t follow scent trails back to food.
Use Essential Oils
Drops of essential oils like peppermint, tea tree, eucalyptus and lavender oil repel ants. Place a few drops along ant trails, around doorways and windows, or mix with water in a spray bottle and use as a natural repellent. Just avoid direct contact with the oils which may harm plants.
Use these natural ant repellent strategies regularly to proactively discourage ants from entering or returning to your home. They are safe to use indoors, outdoors, and around children and pets when used correctly.
IV. Home Remedies for Ant Control
In addition to natural repellents, there are several effective home remedies using common household ingredients that can eliminate existing ant colonies outdoors and indoors. Here are some simple solutions to kill ants without using harsh pesticides.
Borax Ant Baits
Borax contains sodium borate which is a slow acting pesticide and fungicide that disrupts ants digestive systems when ingested. Mixing borax with sugary ingredients creates a bait that worker ants will carry back to feed the colony, eventually killing the queen and causing colony collapse.
Make your own borax ant bait using:
- 1 cup sugar
- 6 tablespoons borax
- 1 cup warm water
Stir the sugar and borax together, then slowly stir in water until well blended. Soak cotton balls in the solution and place them along ant trails and near suspected nesting areas. Ants are drawn to the sweet bait, ingest the borax, and unwittingly poison their colony. This method may take a few days but is very effective at exterminating ants.
Safety Tips:
- Store borax bait gels and mixtures out of reach of children and pets
- Avoid applying borax near edible plants
- Use extreme care to keep borax off countertops and out of food
DIY Ant Sprays
Liquid ant sprays are an easy way to quickly kill ants on contact and eliminate scent trails. Use these solutions sparingly and be cautious around children and pets as the chemicals can be toxic if ingested. Wipe down surfaces afterwards and avoid spraying directly on plants.
Effective natural ant spray recipes include:
- 2 parts vinegar mixed with 1 part water
- 10-15 drops of essential oil mixed with 2 cups water
- 2 tablespoons dish soap mixed with 1 quart water
Use a spray bottle to directly hit ants and nest entrances. The vinegar and soap solutions dissolve ants exoskeletons while the oils suffocate them. Spray trails, entry points and other areas ants frequent to deter them from returning.
Diatomaceous Earth
Diatomaceous earth (DE) is a powder made from crushed fossilized algae that feels like a fine grit. DE is deadly to ants because the sharp particles scratch the waxy coating on insects causing them to dry out and die. Sprinkle a fine layer of DE along baseboards, window sills, ant trails and around outdoor nests. Use a hand duster for easiest application.
Safety Tips:
- Wear a mask when applying to avoid breathing in DE dust
- Keep children and pets away from treated areas until DE settles
- Avoid using DE near heat sources as it can be combustible
DE is very effective at killing ants through penetration of their exoskeletons. Try these homemade remedies first for non-toxic ways to eliminate existing ant infestations indoors and out.
V. Preventative Measures
Prevention is the key to keeping ants out of your home for good. Here are some tips to deter ants by eliminating food sources, sealing up entry points, and removing conditions that attract ants:
Eliminate Food Sources
The biggest lure for ants is easily accessible food. Do not leave out pet food, dirty dishes, crumbs or uncovered human or pet foods. Seal up chips, cereals, sugar etc. in airtight containers. Empty garbage frequently, wipe up spills immediately, and refrain from eating in areas other than the kitchen or dining room. Removing these food attractants will cause ants to lose interest in your home.
Seal Up Entry Points
Inspect window and door frames as well as moldings, cracks, and crevices around pipes and wiring where ants may enter. Seal these areas with caulk or petroleum jelly to block access. Pay special attention to areas where ants have been spotted entering the house. Eliminating entry points forces ants to establish nests and trails farther away from your home.
Remove Ant-Friendly Conditions
Ants prefer dark, confined spaces with ample moisture and warmth. Prune back vegetation and tree branches touching the home’s exterior. Move woodpiles, yard debris, and stones farther from the foundation which can harbor ant nests. Fix leaky pipes, clean out gutters, and ventilate damp areas in basements or crawlspaces to make the environment less inviting to ants. Maintaining a dry home interior also discourages ants.
Keep a Clean Home
Embrace household habits that discourage ants like immediately cleaning up messes in the kitchen, regularly vacuuming and mopping floors, taking out trash frequently, and wiping down countertops. Keep your home free of clutter where food particles and moisture can accumulate. A clean and dry interior is far less appealing to foraging ants.
Making your home as unappealing to ants as possible is key to deterring infestations. Be vigilant in following these hygiene and maintenance steps year-round to deny ants food, water and entry into your house.
VI. Outdoor Ant Control
In addition to indoor ant solutions, taking some steps outdoors around your home’s perimeter can help reduce ant populations:
Use Diatomaceous Earth
Apply diatomaceous earth along the foundation, around trees, under rocks and anywhere else ants may nest outside. The sharp DE particles kill ants outdoors while also creating a barrier of irritation to prevent entry. Reapply DE after heavy rains.
Eliminate Outdoor Food Sources
Pick ripe fruits and vegetables immediately, clear fallen debris from gardens, and remove pet food and waste frequently. Ants thrive on the sugary secretions from plants and proteins in pet food. Eliminating outdoor food resources helps decrease ant numbers.
Natural Repellent Plants
Many plants naturally deter ants with their strong scents, oils or sap. Planting these around outdoor living areas and house foundations can discourage ant nests nearby:
- Peppermint
- Garlic
- Basil
- Celery
- Lavender
- Citronella
- Chili peppers
They can be potted or planted in gardens and yards to repel ants. Crush leaves to release more oils.
Redirect Ant Nests
If you locate an outdoor ant nest near your home, pour boiling water or vinegar on it to kill the colony. The quickest option is to destroy the nest and/or physically remove and relocate it farther from your house. This redirects the ants away from your indoor living spaces.
Targeting outdoor ant populations and nests helps prevent large scale infestations indoors. Implement these measures to make the perimeter of your home as ant-unfriendly as possible.
VII. Common Myths and Misconceptions
When tackling ant problems, many home remedies and solutions for ant control simply don’t work or require safety precautions. Here are some common ant myths and the realities:
Myth: All ants are attracted to vinegar
Reality: Vinegar repels and kills most ant species. Only carpenter ants are attracted to vinegar.
Myth: Coffee grounds repel ants
Reality: Coffee grounds have no impact on ants but can stain carpets.
Myth: Ants won’t cross chalk lines
Reality: Chalk does hinder ant trails but is not a foolproof barrier. Ants can eventually cross over.
Myth: Soapy water kills ants
Reality: Dish soap solutions stun ants but don’t kill them outright. Soap suffocates and removes their chemical trails.
Myth: Banana peels repel ants
Reality: No scientific evidence suggests banana peels deter ants. Fruit peels rot quickly and can attract fruit flies.
Myth: Salt kills ants
Reality: Plain salt does not kill ants. It must be mixed as a brine solution to dehydrate the ants.
Myth: Cucumber peels repel ants
Reality: Cucumber contains acids ants can tolerate. There’s no evidence cucumbers effectively repel ants.
Separate fact from fiction to ensure you use ant solutions that are proven safe and effective. Refer to reputable sources when exploring home remedies for ant control.
