How to Control Garden Ants Naturally

Control garden ants naturally by using homemade remedies such as vinegar, cinnamon, and diatomaceous earth. These methods are safe and effective in getting rid of ants without harming your garden plants or the environment.

Understanding Garden Ants: Identification, Habits, and Lifecycles

Ant Identification

Garden ants are among the most common insects you’ll find in your garden. Ants belong to the family Formicidae and can be classified into different species. They have a head, thorax, and an abdomen with three distinct body parts and six legs. Garden ants are usually small-sized insects ranging in color from black to brown or yellow.

The most common type of garden ant is the worker ant which measures between 2-6 mm in length. Depending on their caste, they may have wings or not. The queen ant is known to grow up to double the size of a worker ant.

Ants have several distinctive features that help identify them:

  • Elbowed antennae
  • Three distinct body parts (head, thorax, and abdomen)
  • Six legs
  • Mandibles

Ant Habits

Garden ants build their nests underground – both deep below the ground surface and relatively shallowly depending on the species. These nest sites offer a protected area where they breed new members of their colony as well as live as communities since they are highly social insects.

Garden ants send out scouts every so often looking for new food sources or potential nesting sites for future colonies. Once found, these scouts leave pheromone trails which provide guidance for other worker ants back to the new site using their sensitive sense of smell

Ants are more active during warm seasons as low temperatures cause them to reduce foraging activities; hence it might seem like there’s no infestation until warmer months come around again.

Here are some habits attributed to these industrious creatures:

  • Foraging – In search of sugar-based nutrients that power their systems.
  • Excretion – Since ants feed upon pre-digested sweets produced by aphids (tiny sap-sucking pests) they scatter waste excreted from digestion along their trails to notify other ants.
  • Nest-building – Ants dig tunnels and create an optimal environment inside; adjusting moisture, temperature, and regulating oxygen through ventilation.
  • Carrying food – Worker ants carry food to the colony as a team activity where older ants transfer it to younger ones.

Ant Lifecycles

To get rid of garden ants quickly, learning about the lifecycle will give you a precise target. Garden ant larvae go through four life stages; egg, larva, pupa and an adult before they are fully grown.

The entire process from egg to adult can take several weeks in some species for instance odorous house ants have colonies with queens that are estimated to produce up to 1000 offspring over their lifetime.

Certain queen ants can mate once in their lifetimes with sperm stored within its body and lead hives containing over 500k members.

Different kinds of garden ants attain maturity at different times:

  • The black garden ant takes five to eight weeks before maturing.
  • The fire ant experiences the lengthiest development – requires months before developing wings as ready-to-mate males or new queens
  • Argentine ant workers mature much quicker than others – and mature way more rapidly when temperatures rise

Garden ant infestations cause distress among most homeowners but understanding their behavior helps prevent future infestations aiding effective control efforts. Homeowners reckon that keeping your garden clean from debris avoids creating suitable nest sites while control measures must be targeted towards environmental modifications such as removing water sources which attract these ubiquitous pests.

What is Natural pest control?

Natural pest control is a method of managing and preventing pests using organic, non-toxic, and eco-friendly techniques such as biological control, physical barriers, cultural practices, and natural repellents. [Wikipedia]

The Dangers of Chemical Ant Control Methods

Ants are notorious for their ability to invade not just our homes but also our gardens. They can wreak havoc on plants, flowers, and even vegetables. It’s no wonder why gardeners want to control them. However, the use of chemical ant control methods is not always the best option. These methods pose dangers not only to humans but also to other beneficial insects and the environment.

Health Risks

When chemical ant control methods are used in gardens, people working or relaxing in the area may be at risk of exposure to harmful chemicals. Some pesticides used in controlling ants can cause skin irritation, allergic reactions, or respiratory distress.

Additionally, some chemicals may linger around longer than intended due to their persistence within the environment. A person exposed to these residual substances could experience toxicity issues that need medical attention and hospitalisation if they manifest in high enough quantities.

A crucial safety concern regarding chemical-based ant control methods is ingestion accidents that happen particularly among toddlers who stumble on tainted soil or leaves with toxic traces. Ingesting some synthetic chemicals could lead to serious medical emergencies and sometimes death.

People typically assume that when applied safely according to product guidelines provided by manufacturers or pest controllers, any potential health risks is kept at bay. Unfortunately, it’s unrealistic because biological factors such as a person’s immune system tolerance levels differ from one another – certain people develop adverse health effects even when exposed under recommended doses while others don’t manifest signs.

Environmental Risks

Like humans’ health concerns raised by chemical insecticides used in gardening activities described above so too are environmental risks posed now share equal relevance as our planet remains ecologically diverse despite human-made development interventions needed for survival(housing units). Garden owners tend to use many forms of pesticides indiscriminately without fully considering their ecological impact between managing pest population levels versus safeguarding birds/bees/wildlife and reduce carbon footprints leading towards a sustainable natural world.

The most significant environmental risk of chemical ant control methods is that they have a long-term effect on soil and water quality. The chemicals used in controlling ants seep into the ground, contaminating it with harmful residues. These residues can penetrate vegetation through their root system and spread to water sources via irrigation systems or rainwater run-offs; thus poisoning them at massive quantities compared to background levels.

Furthermore, these pesticides can kill beneficial insects like honeybees that aid in pollination and maintaining soil health for plants’ growth cycles. Besides, wildflowers that act as host-spots for rare species such as monarch butterflies have short-lived lifecycle intervals because of pesticide-runoffs washing out their food sources.

Harmful Effects on Beneficial Insects

Aside from killing off honeybees, synthetic pesticides significantly reduce diversity among other beneficial insects that help lessen damage caused by garden pests without compromising ecological balances.

Using broad-spectrum insecticides such as pyrethroids (common synthetic insecticide) kills not only targeted pests but also non-targeted insects requiring natural predator ratios necessary in combating unwelcomed species populations. This situation creates an unintended domino effect which ultimately proves detrimental in long-term pest management goals with more complex disruption of ecosystems than if left untreated or using chemical ant control carefully directed towards a specific area avoiding overall exposure instead malicious contamination. Research backs up this trend: studies show that when different classes of pesticides accumulate over numerous treatments cycles become less effective mainly due to resistance build-up within the pest population resulting in ever-increasing inflows of potentially dangerous substances impacting communities’ overall health status(wildlife) increasingly leading global climate change adverse effects wiping out plants’ wider habitat range previously abundant regions, which did not require artificial enhancements hence simplifying biodiversity aspects greatly had now brought down steeply leading into next extinction crises awaiting preventive measures needed promptly reducing chemical footprints today held high values among gardeners to adopt fully practicing alternatives.

To support environmental sustainability, reducing chemical footprints through safe and natural alternatives like essential oils or using well-formulated diatomaceous earth must be highly sought-after options to explore if controlling ants is genuinely necessary.

Natural Ant Control Techniques: Prevention, Repellents, and Traps

Ants in the garden can be quite a nuisance, especially when they start attacking your plants. However, using chemicals to get rid of them is not always the best solution as it may pose risks to other desirable insects, pets and even humans.

Prevention Techniques

Preventing an ant infestation in your garden is easier than getting rid of one. There are various preventive measures you can take to avoid these pests from making their home among your plants:

  • Keep a clean garden – ants are attracted to food scraps and debris. Make sure to keep all areas around the garden free of organic matter that could draw ants closer.
  • Trim tree branches – if you have trees near or close by your house or in the garden itself, their branches could act as bridges for ants travelling from one area to another.
  • Get rid of standing water – Ants are highly attracted to humid environments which make standing water dangerous if left stagnant.
  • Block access points – check for holes or cracks on walls and pavements where ants could use as pathways into your garden. Seal every potential entryway with cement; remember that it only takes a small opening for these tiny creatures to gain access.
  • Plant flowers with natural repellent properties: nature has a way of providing her own solutions which include several flowers like marigolds, chrysanthemums and lavender among others.

Natural Repellents

If prevention techniques fail you then repellents might be what you need:

  • Coffee grounds: Spreading used coffee grounds around plants not only improves soil quality but also stops ants in their tracks because its smell is too strong for them.
  • Cinnamon sticks: Grind cinnamon sticks into powder then sprinkle it on any susceptible areas; made more efficient if combined with pure vanilla extract.
  • Lemon: Lemons can be cut into slices and left near affected areas or mixed with water and sprayed around your yard as its odor repels not only ants but other insects also.
  • Vinegar: Mix equal parts of vinegar and water in a spray bottle; spray around entrances to the house (windows, doors, cracks) and wherever ants have been seen. This solution will not necessarily destroy ants but will send them off to find some place less acidic/helpful.

DIY Traps

Trapping ants is a great way to reduce their numbers found around your garden. You should never attempt exterminating them all because they play an important role in soil circulation. Killing large hordes of them through toxic chemicals may upset the natural balance of the ecosystem:

  • Borax bait: make a homemade ant trap by mixing borax powder, sugar, and water into a paste then leave it where there seem to be ant infestation. The worker ants are attracted by the sugar while ingesting it along with borax then takes it back to their underground nest subsequently killing larger members like queen ant responsible for producing eggs.
  • Sticky traps: use double-sided tape spread on cardboard strips then placed where you normally see lines of marching ants creating a barrier for them – this method might require patience as sometimes several consecutive traps may be required before noticeable reduction occurs.
  • Diatomaceous earth dehydrates insect exoskeletons causing death from dehydration – sprinkle it generously above anthills or onto nests that are visible.

These are just some of the many techniques available for controlling ant infestations without resorting to harsh chemicals which could have detrimental long-term effects on the environment.

Remember that these methods work better if applied early when you still have few problems taking care of rather than waiting until these pests become too much that they start claiming spaces in your living area due to seeking refuge from excess dampness inside houses with greater predictability than outdoor gardens where watering regulations might not lead to waterlogging.

Herbs and Plants That Naturally Repel Ants

Ants are an essential part of the ecosystem as they contribute to soil aeration, decomposition of organic matter, and can also serve as pest control. However, when they start invading our gardens and homes in large numbers, they become a nuisance that needs to be controlled. While there are many chemical insecticides available for controlling ants, these pesticides can be harmful to other beneficial insects and the environment. Fortunately, several herbs and plants repel ants naturally without causing harm to humans or the environment.


  1. Mint:

Mint is well known for its fresh scent and cooling properties; it is also an excellent natural deterrent against ants. Peppermint oil contains strong antispasmodic properties which cause discomfort to ants by interfering with their sense of smell. You can use mint leaves to repel ants by crushing them into small pieces and keeping them in areas where you have seen an ant trail.

  1. Lavender:

Lavender has a lovely fragrance that makes it an excellent choice for use around your home or garden for repelling ants naturally. The aroma produced by lavender interferes with the ant’s pheromones disrupting the way they communicate leading them towards confusion.

  1. Basil:

Basil is not only great for cooking but also serves as a natural repellent against ants due to its potent microbial properties. It works by releasing strong odors that keep ants away from areas where basil leaves are kept or planted.

  1. Rosemary:

Rosemary’s powerful smell makes it another highly effective herb for deterring ants naturally; it produces its fragrant oils from resinous glands located on its leaves making it have scented compounds that insects tend to dislike.

  1. Cinnamon:

Cinnamon goes beyond just being a famous spice; its strong essential oils possess antimicrobial action effective against some pests such as bacteria, viruses, fungi thus eliminating their pheromone trails that ants use in navigation and communication. You can sprinkle cinnamon powder along ant trails or around the garden to discourage their presence.


  1. Marigolds:

Marigolds possess a strong scent that makes them ideal for repelling different types of insects such as mosquitoes and aphids. Their natural chemical make-up kills larvae in the soil and hence act as an excellent deterrent to ants.

  1. Lemongrass:

Lemongrass features powerful essential oils that are effective against a wide variety of pests, including ants; its naturally occurring oil called citral is a natural insecticide. Take some fresh stalks of lemongrass and blend them into a pulp, then apply it on surfaces where you have noticed ants moving.

  1. Chrysanthemums:

Chrysanthemums contain pyrethroids; compounds that are commonly found in pesticides used to control numerous pests due to their lethal effects on arthropods while being non-toxic to mammals so they work effectively but with minimal side-effects on humans.

  1. Pennyroyal:

Pennyroyal’s pungent aroma has been used over time as an insect repellent; it contains highly volatile compounds like menthol, pulegone, and limonene, which give it antiseptic properties useful for preventing fungal infections caused by plants’ roots’ decay following ant infestation.

  1. Thyme:

Thyme is another herb that releases fragrant essential oils known to be repellent to various insects like ants and mosquitoes due to the chemical compound thymol present which acts directly on the nervous system of these pests decreasing their activity levels.

The Benefits of Companion Planting for Ant Control

When it comes to garden pest control, companion planting is a great natural solution that not only helps to keep pests away but also provides other benefits such as improved soil health and diversity. One of the most common and annoying garden pests are ants. These tiny creatures can cause damage to plants, potted herbs, and even vegetables.

Ants are drawn to gardens because they’re fond of the sweet nectar produced by flowers and the sugary substance produced by aphids. They also create underground tunnels that can weaken roots leading to poor plant growth. Instead of reaching out for chemical insecticides, which could be harmful to your plants or even harmful insects like bees, why not try companion planting?

Plant Combinations

Different plant species give off different aromas that can either attract or repel certain insects and pests while also enhancing or harming each other’s growth process. There are several plant combinations that work great for ant control:

  • Mint (mentha spp.) + chives (alliaceae spp.) – Mint has a strong aroma that ants don’t like while chives produce sulfur compounds that deter them.
  • Marigold (tagetes spp.) + garlic (allium sativum) – Marigolds secret root exudates that kill nematodes in the soil while garlic gives off an aroma that keeps ants at bay.
  • Tansy (tanacetum vulgare) + catnip (nepeta cataria) – Tansy produces tannins which repel many insects including ants while catnip sends out an odor from its leaves irritates them.
  • Lavender (lavandula spp.) + rosemary (rosmarinus officinalis) – Lavender’s fragrant odor covers up the scent trails left by ants making navigation hard for them while rosemary secretes chemicals that are toxic to ants.
  • Lemon Thyme (thymus x citriodorus) + sage (salvia officinalis) – Lemon thyme is a natural antiseptic and immune boosters while sage’s strong odor prevents them from entering your garden.

Benefits of Companion Planting

Apart from providing a natural way of pest control, companion planting has other several benefits like:

  1. Reduced pesticide use – By planting specific species together, you reduce the reliance on harmful pesticides which could harm the plants and soil as well as the environment.
  2. Improved soil health – Different plant species have different nutrient requirements; therefore, growing them together can enhance the quality of your soil by adding diverse nutrients and reducing soil erosion.
  3. Attractive appearance – Companion planting gives an aesthetically pleasing look to your garden as it adds color, texture, and contrast.

Gardening is all about balance. With companion planting for ant control in mind, be sure to monitor its effectiveness regularly. If you notice increased activity even after implementation, try moving plant combinations around or increase the number of plants in your bed where needed.

Home Remedies for Ant Elimination: Vinegar, Borax, and Diatomaceous Earth

Ants in your garden can be a nuisance as they might damage the plants by controlling aphids, fungus, and other insects. Garden ants also bring their colony to your house, contaminating your food, destroying electrical wires, and creating dirt piles. Often considered a pest only during the summer months when they are most active, ants require year-round attention as they can invade homes at any time of the year. Chemicals used to eliminate ants may harm the environment but there are several natural remedies that you can use to get rid of them without harming Mother Nature.


Vinegar is the most common natural ingredient found in almost every household. It is acidic in nature making it an excellent ant repellent formula for countertops, windowsills or even gardens. Spraying vinegar on ant-infested areas will produce a pungent smell which interferes with their sense of smell. As a result, this disrupts their trail marking system disrupting their entry points thus preventing them from entering your house or affecting garden plants.

To make vinegar ant spray:

  • Combine equal amounts of distilled white vinegar & water
  • Pour mixture into a spray bottle
  • Spray on areas where ants are present like counters and window sills
  • Repeat daily or until you see no traces of the ant invasion


Borax helps you kill ants effectively because its crystals slice through their bodies resulting in dehydration from body fluids loss thereby killing them gradually over time. When mixed with sugar water it acts as a bait irresistible to ants who will consume it leading to survival problems within their colony.

To make borax bait:

  • Mix together 1 tablespoon borax powder with 1 tablespoon granulated sugar
  • Add 2 tablespoons warm water
  • Soak cotton ball(s) in mixture
  • Place cotton balls near entry points where you see ants frequently
  • Replace cotton balls with fresh ones every 2-3 days.

Pro tip:Borax needs to be mixed in small quantities because its powder can act as an irritant when it’s inhaled causing respiratory problems. It also should not be used if there are kids and pets at home for the same reasons.

Diatomaceous Earth

Diatomaceous earth (DE) is a type of soft sedimentary rock that consists of fossilized phytoplankton named diatoms. The DE used here is known as food grade meaning it will not harm your family or pets if ingested while pool grade DE has added chemicals making it dangerous to mix with skin or ingest.

As a remedy, the abrasive microscopic sharp edges contained in porous DE scratch through an ant’s exoskeleton resulting in dehydration by destroying their body fats leading them to die off slowly over time.

To create a barrier against ants using DE:

  • Sprinkle some food-grade diatomaceous earth at entry points such as cracks, crevices and window sills
  • Avoid breathing its dust particles
  • Use gloves especially when pouring large amounts
  • Repeat application after rainfall.
Food-Grade DE vs Pool-Grade DE

It’s essential always to check labels before purchasing any grade of DE product because most contain herbal pesticides that lure ants due to their sweet scent.

Food-grade Diatomaceous Earth (DE) is safe for plants and can kill several types of garden pests if they come into contact with it. Also, It’s safe for human consumption if ingested accidentally but care must be taken so you do not inhale the small particles which can cause lung irritation.

On the other hand, Pool-grade Diatomaceous Earth has chemical additives like chlorine which make this product poisonous thereby increasing toxicity levels thus cannot be used near plants or animals

Final thoughts:

These three natural ant remedies are cost-effective, efficient against ants, and nontoxic to the environment. However, it would be best to understand that even though they are natural remedies, there is still a need for caution; wearing gloves to protect hands while applying any of these remedies is necessary as skin sensitivity varies from person to person. When children and pets are around, Borax should be avoided as inhalation or consumption can result in health hazards. Try each of the remedies to find out which suits your situation best.

Happy gardening!
