How Can You Effectively Get Rid of Ants in Your Garden?
For many, a garden is a place of tranquillity, a slice of nature right at one’s doorstep. But what happens when tiny invaders threaten this peace? You’ve guessed it—we’re talking about ants.
While they might be nature’s marvels in many ways, they can be quite the pesky intruders in our gardens. Let’s explore how to get rid of ants in your garden, while striking a balance between eco-friendly methods and quick fixes.
Understanding Ants in UK Gardens
Ants are an essential part of the garden’s ecosystem, but when their population surges, they can become a homeowner’s nemesis. Understanding these fascinating creatures can help with efficient ant control, ensuring they don’t overrun our garden beds or damage plant life.

Ant Activity Patterns
In the UK, ants, be they common garden ants or less frequent carpenter ants, are most active during spring and summer. This activity aligns with favourable environmental conditions.
Homeowners should be aware of this pattern, as it’s during this period that ant infestations can surge. And while ants in the garden can play a role in controlling other pests, an unchecked population can lead to issues like ant hills damaging the lawn grass or ants defending aphid colonies, exacerbating an aphid problem.
Types of Ant Species You May Find in Your Garden
Black/Garden Ant (lasius niger)
This ant species is perhaps the most recognised in UK gardens. Known to march straight for the source of food, it’s no wonder they often find their way into our homes, making ant extermination a topic of interest for many.
Appearance and Habitat: These black ants nest almost anywhere: under pavements, alongside the lawn surface, and even in compost heaps. With an ant colony size ranging between 4,000 to 15,000, it’s not uncommon to spot a few ants during a stroll in the garden.
Diet: Predominantly, these ants eat insects, but they’re also attracted to sugary substances. They’ve even been recorded feeding on the bodies of their fallen comrades or ants from other colonies.
Defence Mechanism: Their primary means of defence includes the use of formic acid and their jaws, ensuring any ant invasion is a force to be reckoned with.
Yellow Meadow Ants (lasius flavus)
Often mistaken for a red ant due to its yellow-orange hue, the yellow meadow ant is another common species in UK gardens.
Appearance and Habitat: Renowned as the most skilled nest builders, these ants can construct both small mounds in our gardens and larger ant hills in fields. If you’ve ever stepped on an ant hill while enjoying a community gardening event, there’s a good chance it was this species.
Diet and Behaviour: These ants tend to forage below ground. As a result, homeowners rarely spot them unless their nest is disturbed or during their mating flights. But bear in mind, they’re still there, working tirelessly below the surface.
Red Wood Ant/Horse Ant (formica rufa)
A common species found on the fringes of UK forests.
Appearance and Habitat: Formica rufa ants, also known as wood ants, are fascinating creatures known for building massive mounds from pine needles. When it comes to ant hills, theirs are architectural marvels.
Behaviour: These ants are notably aggressive. If disturbed, they bite and spray formic acid. This combination makes them effective defenders, ensuring their ant colony thrives.
Special Mention – As the largest ant in the UK, it raids other ant species’ nests, like the Formica fusca, and adopts their brood. Talk about a twist in the ant world!
Black Wood Ant (formica fusca)
This ant species, though a wood ant, is more timid than its red counterparts.
Appearance and Habitat: With a black hue, these ants prefer to nest under decaying logs. They’re typically found from the Midlands to Southern England, making them a common sight for those into wildlife gardening.
Colony Dynamics: Their colonies are smaller, often housing fewer than 1,000 ants. While they can have multiple queens, the number is usually minimal compared to other ant species.
Natural Remedies to Deter Ants
In the quest to control ants in our gardens, many of us prefer the organic route. Natural remedies not only ensure our gardens’ ecosystem remains balanced, but they also prevent the harm that can come from harsh chemicals. Let’s delve into some of these fantastic pest control methods.
Diatomaceous earth, often abbreviated as DE, is a powdery substance derived from fossilised aquatic organisms known as diatoms. It’s completely harmless to larger organisms, making it an organic food-grade solution for various pests.
It acts as a microscopic barrier, deterring ants from marching through. The sharp edges of DE particles cause tiny cuts in ants, leading to dehydration. This method ensures ant populations don’t surge out of control. Moreover, DE doesn’t just protect against ants.
It’s known to be effective against most ants and other insects that might cause damage to garden plants. However, bear in mind that while it is a potent ant killer, it doesn’t harm our green buddies, the plants.
Lemon Juice & Water Spray
Certain scents attract ants, while others repel them. Lemon is one such scent. By simply mixing lemon juice with water in a spray bottle, you have an eco-friendly ant repellent.
Spraying this concoction on ant trails disrupts their scent trails. It acts as a gentle reminder for ants that they aren’t exactly invited to the garden party. Over time, ants in the garden might find it less appealing to march into areas where they constantly lose their way.
While homeowners might adore the refreshing scent of peppermint, ants bite the bullet and tend to steer clear of this aroma.
Dabbing a little peppermint oil around garden beds or even on compost bin lids can make a world of difference. Not only does it repel ants, but it also keeps other pests at bay. And as ants feed on various sources, disrupting their path with this aromatic oil can reduce the ant larvae’s food source.
Sometimes, when the ant hills become too pronounced or an ant invasion is significant, one might consider drastic measures.
Pouring boiling water directly over ant nests can yield immediate results. Worker ants, the ones that gather food and protect aphids for their sugary secretions, can be significantly reduced using this method. However, always use with caution to avoid damaging plant roots or beneficial microscopic worms in the soil.
Chemical Solutions for Quick Results
While natural remedies have their charm, there are times when homeowners prefer a quicker route to managing ants in the garden. Enter chemical solutions: faster, more efficient, but requiring a mindful approach.
Ant baits are the long game in the realm of ant control. By using these bait stations, you’re not just targeting individual ants but the entire colony.
Think of it as a Trojan horse. The worker ants are attracted to the bait, which they carry back to the nest, unknowingly introducing a harmful agent to the entire community.
The beauty of ant baits is in their comprehensive approach. When ants share the bait with their colony, it reaches even the ants that usually remain hidden, such as the queen and the ant larvae.
Consequently, this method disrupts the ants’ life cycle, reducing their population considerably over a few weeks. Moreover, while the bait might look like food to ants, it’s harmless to larger garden critters.
Insecticidal soaps offer an eco-friendly way to tackle ants and other pests. Made from organic material, they provide an alternative to the more aggressive chemical sprays available at garden centres.
When sprayed onto ants, the fatty acids in the soap break down their protective layer, causing dehydration and eventually killing the ants. It’s a kinder, gentler cousin of chemical sprays but is still effective in keeping ants at bay.
Because it’s derived from organic matter, it doesn’t harm the garden’s ecosystem or beneficial insects. Also, using this method ensures that flower beds remain undamaged and the root system of garden plants stays intact.
Sometimes, when an ant invasion gets too overwhelming, homeowners might consider bringing out the heavy artillery—chemical sprays. They deliver quick results, targeting ants on the spot and deterring them from marching back.
While chemical sprays can be effective, it’s crucial to use them with discretion. Always read the label and ensure they don’t harm beneficial garden critters.
Also, it’s good to bear in mind that while they target ants, they might not be the best long-term solution for controlling ants. Overuse can lead to a build-up in the soil, affecting plant sap absorption or even attracting other predators.
If you opt for chemical sprays, consider wearing gloves and using a spray bottle to target specific areas, avoiding any accidental damage to plants by type or harming beneficial insects like bees.
Keeping Garden Pests at Bay
Garden Hygiene is Key
Gardening isn’t just about planting and watering; it’s about maintaining an environment that’s in harmony. When it comes to ant control, a proactive approach centred around garden hygiene can often prevent the need for reactive measures, be it the use of ant powders or boiling water remedies.
A tidy garden is not only a delight to the eyes but also a tactical approach against pests like ants. Regularly clearing fallen leaves, ensuring plant pots are free from excess water, and removing old wood can keep many pests at bay.
Starving the Intruders
Ants march into gardens, primarily in search of food. By cleaning up food sources, including the tiny insects they prey upon, and ensuring no food-grade diatomaceous earth or similar attractants are left around, homeowners can make their plots less appealing. Think of it as ensuring the ants in the garden don’t get their version of a farm cow!
Keeping Unwanted Guests Out
Like any home, a garden has its entry points. Whether it’s small gaps in the fence or the boundaries created by flower beds, ensuring these areas are sealed can deter ants. It’s a bit like shutting the door on uninvited guests.
Using natural barriers such as crushed eggshells or even sprinkling substances like boric acid can prevent ants from entering. A layer of baking soda or baby powder, both completely harmless to plants, can act as additional barriers.
And if you’re feeling a bit creative, citrus peels, especially from lemons and oranges, can be a fragrant deterrent, ensuring ants think twice before they make an entrance.
Every homeowner should understand the balance of nature. While ants have their role in the ecosystem, so do their natural predators. Embracing this biological control method can be beneficial.
Birds can be a homeowner’s best friend. They not only serenade us with their songs but also feast on ants, keeping their populations in check.
Similarly, delightful hedgehogs, often found roaming gardens during the night, love to snack on ants.
Encouraging these creatures, be it through bird feeders or hedgehog-friendly spaces, ensures a win-win for all: you get to enjoy their company, and they help manage the ant population.
