Ants In Raised Bed Garden: Causes and Easy Control

Spread the Word!

Ants are a common sight in gardens, and they can positively and negatively affect the soil and plants.

Ants can aerate the soil and help to break down organic material. They can also keep pest populations in check by preying on other insects. However, too many ants can cause damage to your plants. Ant populations can be controlled by using diatomaceous earth, sticky barriers, orange guard, and liquid ant baits to keep ants away.

In this article, we’ll explore the benefits and drawbacks of having ants in your raised bed garden and how to get rid of them if necessary.

Why Are There So Many Ants in Your Garden Beds?

Ants in Garden Beds

You may be wondering why there are so many ants in your garden beds. The answer lies in the presence of aphids, mealybugs, and sheltered areas.

Aphids secrete a sugary substance that attracts ants, while mealybugs are one of their favorite food sources.

Additionally, sheltered areas like mulch and compost piles provide the perfect environment for ant colonies to thrive.

Aphids Can Increase Ant Population

By providing an ideal environment for aphids, you’re helping to create a perfect habitat for the ants to thrive.

Aphids feed on plant sap and produce honeydew, which attracts ants. Ants protect aphids from predators in exchange for this food source, increasing ant populations in your garden beds.

To reduce the number of ants in your raised bed garden or vegetable garden bed, consider using natural solutions such as ant baits, hot water, or food-grade diatomaceous earth.

Mealybugs attract ants

Ants feeding on mealybugs

Moving on from aphids, mealybugs are another insect that can attract ants to your raised bed garden.

Mealybugs feed on the sap of garden plants and excrete a sugary substance called honeydew which is attractive to ants.

Ants will then protect the mealybugs from predators in exchange for the honeydew they produce.

The dead insects left behind by the mealybugs also provide an additional food source for ants.

In addition, natural ingredients such as brain cells and digestive tract found in mealybug secretions can also be beneficial to ant colonies.

Sheltered Areas

Loose mulch

Providing sheltered areas in your garden will give ants the perfect place to congregate and build their nests.

Organic materials such as mulch, rocks, logs, and soil can provide a dark, cool environment for ants to thrive in vegetable gardens.

Additionally, these structures can create pathways for other insects, which may benefit plant pollination.

Benefits of Ants in Raised Garden Beds

Ants are a great addition to raised garden beds! They can help aerate the soil, making it easier for air and water to reach the roots of your plants.

Additionally, they can assist with pollination as they travel through the garden and transfer pollen from flower to flower.

Not only do ants provide a boost to garden health, but their presence also helps control pests like aphids, which can be harmful to your plants.

Soil Aeration

Soil Aeration

Aeration of the soil is essential for creating a thriving environment for any creature, especially ants in raised garden beds.

Worker ants effectively aerate the soil, benefiting vegetable gardens greatly. The aeration process ensures each ant colony has enough oxygen and moisture for growth.

In addition, loosening compacted dirt creates air pockets promoting healthy root systems in plants. Regular soil aeration in raised garden beds promotes healthier ant colonies and more bountiful vegetable harvests!

Assist with Pollination


Ant populations not only help to aerate garden soil, but they can also play an important role in helping with pollination.

Like many insects, ants love nectar – a plant secretion that attracts pollinators to help spread their pollen so they can germinate and spread.

However, ants are considered as nectar robbers that do not provide effective pollination service.

Disadvantages of Ants in A Garden

Ants in your garden can cause many issues. They could bite you, spread unwanted pests, and even damage plants.

Not only can they nip at your skin when disturbed, but they can also bring other unwanted guests, like aphids and mites, into the garden.

In addition, ants may feed on plant sap or burrow around various roots, causing destruction to the plants. All of these problems can be detrimental to a thriving garden ecosystem.

Ants Can Bite You

While tending your garden, it’s important to be mindful of the potential for ant bites. Ants can bite you in order to protect their nest and defend against intruders – they have sharp mandibles that can deliver a painful sting.

Ants Could Help Spread Unwanted Pests

Plant Pests

Ants can move larvae and eggs from one area to another without you even knowing, which may lead to an infestation of undesirable insects.

They carry these pests and can introduce them into your garden or home, creating an unwanted environment for both you and your plants.

To prevent this from happening, it’s important to regularly check your raised bed gardens for any signs of ant activity and take the necessary steps to eliminate them.

This could include creating a perimeter barrier using diatomaceous earth or sticky traps to keep the ants from entering your space.

Damage to Plants

Moving on from the potential risks of ants spreading unwanted pests, it’s important to consider their impact on plants.

While some ants may help to aerate and fertilize the soil, which can be beneficial for a garden, there are also many species that feed on plant sap.

This can damage stems and leaves physically, leaving them yellow or discolored and potentially stunting their growth.

Additionally, large ant colonies can strip trees of their bark or kill saplings if left unchecked.

To ensure your plants stay healthy in a raised bed garden with ants nearby, it’s important to assess the level of ant activity and take steps towards controlling them if necessary.

How To Kill Ants in Garden Beds

If you’re looking for ways to kill ants in your garden beds, there are several options available.

You can set up an ant bait, use boiling water to kill them, apply neem oil to their nest, spray insecticidal soap on them, hose them off with water, sprinkle diatomaceous earth around the area or use orange guard.

All of these methods are effective and easy to implement. However, it’s important to understand how each one works before deciding which is best for your situation.

Set up an Ant Bait

Setting up an ant bait is the next step to take in controlling these pesky critters.

To do this, you’ll need to:

  • 1. Buy a commercially made ant bait product.
  • 2. Place several pieces of the bait in areas where ants are visible.
  • 3. Ensure the bait isn’t accessible to children or pets.
  • 4. Monitor the area regularly to ensure that your efforts are successful.

The key here is to use a product specifically designed for killing ants, as it’ll contain ingredients that attract them and act quickly enough to make a difference.

Use Boiling Water to Kill Ants

Boiling water is a simple yet effective way to get rid of ants and keep them from coming back.

It’s an easy, cost-effective solution that can be used in raised bed gardens without the need for harsh chemicals or expensive pest control services.

To use boiling water to kill ants, you’ll need to pour it directly onto the ant hills or nests.

The boiling water will instantly kill any ants it encounters and destroy their eggs and larvae.

Additionally, the heat will help break down the structure of the nest, making it difficult for new colonies to form in their place.

Apply Neem Oil to Ant’s Nest

Take the fight to those pesky critters with neem oil, an easy and natural way to keep them away from your outdoor space.

Neem oil is typically derived from the seeds of the neem tree and has long been used as a natural pest repellent.

It can effectively kill off colonies in gardens or flower beds when applied directly to ant nests.

Applying Insecticidal Soap

Insecticidal soap is another effective way to fight off those pesky intruders and keep them from invading your outdoor space. It works by disrupting the cell membranes of the ants, which causes dehydration and death.

Insecticidal soaps are generally safe for use around humans and pets, but it’s important to read the label carefully before using any product.

When applying insecticidal soap, be sure to spray directly onto the ant nest or mound as well as on any visible ants. This will help ensure that all the colony ants are affected by the treatment.

Additionally, you should reapply every few days until you no longer see any signs of ant activity in your garden.

Hosing Them Off With Water

Hosing off the area with water is another great way to get rid of those pesky ants and keep them from coming back. This method can be used as a preventative measure or after you’ve already seen signs of an infestation.

When hosing off the raised bed garden, make sure to use a strong stream of water that will reach deep into crevices and cracks where the ants may have burrowed.

Pay special attention to areas near plants and other food sources for the ants; these are often their favorite spots.

Doing this regularly – every few days – can help ensure that your garden remains ant-free! So, grab your hose and give it a go!

Diatomaceous Earth

Diatomaceous Earth

Sprinkle diatomaceous earth around your outdoor area like a blanket of protection, and keep those pesky critters from invading your space.

Diatomaceous earth is an effective way to deter ants from entering your raised bed garden.

Its particles have sharp edges that look like broken glass when examined under a microscope. These edges are able to cut through an insect’s exoskeleton, and the powder sticks to its feet and skin.

Once the insect’s body moisture absorbs the powder, the insect dehydrates and dies.

Orange Guard

Protect your outdoor area from pests with Orange Guard, an easy-to-use insecticidal spray that’s safe for children and pets.

This product is a great choice for those looking to keep their raised bed garden free of ants without the need for harsh chemicals.

The active ingredient in Orange Guard is d-Limonene, derived from citrus fruits and proven effective against a wide range of pests. It has low toxicity levels and doesn’t leave behind any unpleasant odors or residues.

With its simple application process and long-lasting effects, Orange Guard provides an ideal solution for keeping your raised bed garden ant-free.

Frequently Asked Questions

Are there any natural deterrents to keep ants away?

You may want to consider using natural deterrents to keep ants away from your raised garden beds.

A few of these include spreading diatomaceous earth, setting up barriers such as cedar mulch or pine needles, planting mint or citronella around the bed, and spraying a mixture of dish soap and water on the ant hills.

Cedar mulch works because it repels bugs with its strong scent.

Mint and citronella are plants that contain natural oils that act as a deterrent for ants.

Finally, dish soap mixed with water creates a barrier on the ant hill that will disrupt their scent trails and cause them to lose their way back home.

The Takeaway

You’ve seen the benefits of having ants in your raised garden beds, but you may be wondering if there are any drawbacks. Unfortunately, too many ants can cause damage to plants and disrupt the balance of your garden.

If you find that you have an ant infestation, it’s important to take action quickly. Use natural methods such as diatomaceous earth or borax to kill off the ants without harming other beneficial insects.

With a little effort and patience, you can keep your garden healthy and thriving with minimal ant interference.
