Nothing’s more annoying than stepping out in the morning and finding your garden covered with tiny, dark-colored ants. Carpenter ants can invade almost any yard and make it their home, ruining your carefully-tended plants and landscaping.
Fortunately, there are ways to get rid of this pesky insect and keep your garden looking beautiful.
In this article, we’ll go over some carpenter ant control tips and tricks to help you keep carpenter ants from wood mulch. From using natural repellents to taking preventative measures, you can learn how to keep these destructive pests away from your yard and enjoy peace of mind when you’re outside.
Carpenter Ants & Mulch: At a Glance
Before we jump into how to get rid of carpenter ants in your mulch, it’s important to understand why they thrive in this environment. Carpenter ants love wood.
Carpenter ants are one of the largest ant species in the US, and they typically nest in decaying or damaged wood. They are particularly drawn to soil moisture and cedar mulch, where the worker ants can burrow and build a carpenter ant nest without being disturbed.
Unlike termites, which feed on wood, carpenter ants simply use it for nesting. This means that they can cause damage to your garden mulch and yard, but they don’t eat wood itself.
Nevertheless, carpenter ants are extremely destructive, and their presence can lead to the destruction of your landscaping, the death of your plants, and even damage to your home if left unchecked.
Techniques for Getting Rid of Carpenter Ants in Mulch
Fortunately, there are several simple steps that you can take to get rid of carpenter ant infestation in your mulch and prevent them from coming back.
Let’s take a closer look at these tips and tricks.
Use Natural Repellents
Why go through the hassle of going to the store and buying expensive sprays and chemicals to get rid of carpenter ants in your mulch when you can use simple natural repellents?
One of the most effective ways to keep carpenter ants away from your mulch is to use a homemade repellent made with essential oils. Peppermint, thyme, cinnamon, clove, and rosemary are all effective at driving away these pests.
Simply mix a few drops of these essential oils with water in a spray bottle and apply generously to your mulch. This will help keep the ants away without causing any harm to your plants or soil.
Keep Your Mulch Dry and Maintain It Regularly
Carpenter ants have a difficult time living in dry areas, so it’s important to keep your mulch free of moisture and make sure that it is well-drained to discourage these pests from making their home there.
Additionally, it’s important to maintain your mulch regularly. A thick layer of unkempt mulch is much more attractive to carpenter ants and other unwanted pests than a thin-layered or well-groomed mulch.
Stirring your mulch and removing dead plants and other debris can help keep carpenter ants at bay and make your yard more aesthetically appealing.
Keep Your Mulch’s Layer Thin
Another simple way to reduce your chances of attracting carpenter ants is to keep the thickness of your mulch layer manageable.
Carpenter ants will have a hard time creating a deep and secure nest in shallow layers of mulch, so it’s important to avoid piling up a thick layer when you’re doing your yard maintenance.
Instead, try to keep your mulch layer to a maximum of 3 inches in depth, and consider spreading out a thin layer of mulch over multiple days rather than adding it all at once. This will help keep your mulch looking neat and tidy while discouraging these destructive pests.
Set the Mulch Away From Your Home
This should go without saying, but it’s important to keep your mulch far away from your home.
Carpenter ants will find their way into the cracks and crevices of your house if they have easy access, so be sure to keep a good distance between your mulch and the foundation of your property.
The ideal distance is at least 10 feet away from your home, but the farther, the better if you can manage it. You may need to adjust this distance depending on your property’s size and the landscaping layout, so be sure to talk to a professional about what’s most suitable for you.
You should also make sure that there are no trees close to your mulch, as these can serve as a bridge for carpenter ants to move between your mulch and your home.
Keep Your Yard and Landscaping Well-Organized
Finally, it’s important to keep your landscaping well organized and maintained. This means keeping walkways and paths clear of debris, trimming back overgrown trees and plants, and removing any clutter that may attract carpenter ants.
Keeping your yard well-organized can help prevent these pests from taking up residence in your mulch or finding their way into your home.
Yes, we know it’s time-consuming and tedious, but the effort is well worth it in the end.
DIY Treatment for Carpenter Ants in Mulch
In addition to the above-mentioned tips, there are several simple DIY treatments that you can try to get rid of carpenter ants in your mulch.
These are easy to make and use, so they’re a great option if you prefer a more natural and organic approach to pest control.
One such treatment is borax, which you can find at most hardware stores or home improvement stores.
Here’s what you’ll need to do:
- Combine 3 parts borax with 1 part sugar and mix well with boiling water until fully dissolved.
- Pour the solution into a spray bottle, then generously apply it over some cotton balls, which you will then cover with tin foil.
- Place the cotton balls in inconspicuous areas of your mulch, such as around trees, bushes, or plants.
The hungry carpenter ants will be drawn to the sugary solution and will then take the borax back to their nests. Once ingested, the borax will take effect and kill the ants.
Wrapping Up
No one likes having pests in their yard, so it’s important to take steps to get rid of carpenter ants in your mulch before they cause too much damage.
By following these simple tips and using some of the DIY treatments above, you should be able to keep your yard safe from carpenter ants and other pests.
