Many gardeners face the challenge of ants invading their precious plant beds. And although ants can have both positive and negative impacts on your garden, it’s understandable that you might want to get rid of them.
Let’s find out how to reclaim your garden from these little intruders!
What are Raised Garden Beds?
Before we talk about ants in raised garden beds, let’s understand what a raised garden bed is. It’s a gardening method where you make a contained area for planting.
These beds are usually raised above the ground and filled with soil, giving you more control over water, drainage, and soil quality.
It has its advantages like easier access, less weed growth, and better pest control. But sometimes, ants can get into these beds. So, what types of ants will you find in raised garden beds?
What Types of Ants Infest a Raised Garden Beds?
You might see various types of ants in your raised garden beds. Identifying the specific ant species is important to understand their behavior and how they might affect your garden. Here are some common types you might find:
- Carpenter Ants:
These ants are known for their ability to tunnel through wood. Although they don’t eat wood like termites, they can still damage wooden structures in your garden, like raised bed frames or wooden fences.
- Fire Ants:
Fire ants are well known for their painful stings. They can be aggressive and are always in large colonies, which can be bothersome in your garden. Their presence can make activities like harvesting not a so fun experience.
- Argentine Ants:
Argentine ants are an invasive species that create huge supercolonies. They can upset the natural balance in your garden by out-competing native ant species and other helpful insects.
- Pavement Ants:
These ants are often seen in urban areas and can build small mounds of soil in your raised garden beds. While they usually don’t harm plants, their presence can be unattractive.
What Are The Benefits of Ants in Raised Garden Beds?
Having ants in raised garden beds can be beneficial in several ways.
First, ants help improve the soil by digging tunnels, which increases oxygen levels and makes it easier for plant roots to grow.
They also help with nutrient cycling by moving organic matter and nutrients around in the soil, which is good for plants.
Some types of ants eat pests like aphids and caterpillars, which helps keep the population of pests under control.
Additionally, some ants help spread seeds to new areas, which can help plants grow in different places.
Disadvantages of Ants in Raised Garden Beds
Having ants in raised garden beds has some downsides. First, ants like fire ants, can harm plants if they nest near their roots.
Second, ant tunnels can mess up the soil, which might lead to erosion or uneven nutrients in the soil.
Third, ants can get into the house from gardens.
Fourth, ants might compete with plants for things like nectar, which could affect how well plants grow.
It’s important to watch for ants in raised garden beds and deal with them if they become a problem.
How to Get Rid of Ants in Raised Garden Beds
If ants are causing problems in your raised garden beds, there are several ways you can control and get rid of them. Here are some effective strategies you can use:
1. Diatomaceous Earth
Diatomaceous earth (DE) is a natural and safe substance that can help get rid of ants in your raised garden beds. It’s made from fossilized diatoms, a type of algae. DE works by dehydrating ants and other insects, which eventually kills them. To use DE:
- Spread a thin layer of DE around the perimeter of your raised garden bed and any areas where ants are entering or moving in trails.
- Reapply the DE after heavy rains or whenever you see that it’s needed.
- Wear a dust mask when applying DE to avoid breathing in the fine particles.
2. Natural Repellents
There are several natural substances that ants find repulsive and can help deter them from your raised garden beds. Here are a few options:
- Cayenne Pepper: Sprinkle cayenne pepper around your garden beds to create a barrier that ants are less likely to cross.
- Cinnamon: Like cayenne pepper, ants dislike the smell of cinnamon. Sprinkle it around your garden beds or create cinnamon-infused water and spray directly on ant trails.
- Citrus Peels: Ants are not fond of citrus scents. Place citrus peels, such as orange or lemon peels, around your garden beds to repel them.
3. Borax and Sugar Bait
You can make homemade borax and sugar bait to control ants in your raised garden beds. Here’s how to do it:
- Mix equal parts borax and granulated sugar in a bowl. For example, use 1/2 cup of each.
- Add enough water to make a thick paste
- Put small amounts of the paste in shallow containers, like jar lids or bottle caps.
- The ants will be attracted to the sweet sugar, but the borax will act as a slow-acting poison, eventually eliminating the colony.
- Keep the bait away from kids and pets, as borax can be harmful if eaten.

4. Boiling Water
If you find ant nests in your raised garden beds, pouring boiling water over them can be a good way to kill ants. But be careful, as boiling water can also harm your plants. Here’s how you can do it safely:
- Boil a pot of water.
- Carefully pour the boiling water directly into the ant nests.
- Repeat the process as necessary until the ant colonies are gone.
