Join us today as we talk about how to get rid of termites in mulch and learn about the best tips, tricks, and products you can use to protect your property and home in the future.

But First, What Are Termites?

1 termites
Termites are not related to ants, though they do look an awful lot like them.

Termites are eusocial insects in the order of Blattodea. Though they look an awful lot like ants, termites are not related to ants and instead belong to an order of their own.

There are about 45 different species of termites throughout the United States, with all of them falling under three categories including subterranean termites, dry wood termites, and damp wood termites.

When it comes to termites in mulch, you’ll likely be dealing with subterranean termites. These pests live below ground and consume the cellulose from wood and paper to survive. They also require moisture and other factors to ensure they are living in an ideal environment.

If you have encountered termites in mulch, you likely are encountering worker termites and swarmer termites.

Worker Termites

Worker termites are the termites tasked with collecting food for their colony. They also work to build those telltale mud tubes that are a common sign of termite infestations as well as nests inside the colony for their young.

Swarmer Termites

Swarmer termites are adult termites that have developed wings. They are called swarmers because they emerge from their nest in swarms to mate. Upon mating, swarmer termites lose their wings and often leave the colony in search of building their own colony.

How Big Is A Termite Colony?

Although termites in mulch may not seem like a big deal at first, the truth is that these insects could easily and quickly find their way inside your home, where they can cause costly and even dangerous structural damage.

Termite colonies are massive, and once they become overcrowded some termites will look to make other colonies elsewhere. If mulch is close to or touching the siding of your home, vulnerabilities to your foundation could become the perfect entrypoint for the next colony.

Colonies of termites can reach numbers between 60,000 to one million, and colonies can last for decades if left untreated.

Why Do I Have Termites In Mulch?

Though mulch is wood, it is not necessarily what attracts termites.

Termites feed on the cellulose in wood and paper, often causing severe and irreparable damage to homes, trees, and wood structures.

With that being said, mulch itself does not attract termites. Although mulch is made of wood, it is generally the application of mulch that is attractive to these pests.

Subterranean termites require moisture and a safe shelter to build their nests, and mulch that is applied to gardens or perimeters up to three inches deep provides the perfect environment for these pests.

Mulch can also attract a number of other pests like earwigs, spiders, pillbugs, slugs, and even ants. Many people prefer using mulch in their garden because it helps reduce water loss in soil. Mulch can also help plants to thrive and may even suppress the growth of certain weeds.

The good news is that using mulch does not necessarily mean you will automatically wind up with termites. In fact, there are correct ways to apply mulch to help keep termites in mulch from becoming a common occurrence.

But before we talk about the best methods to prevent termites in mulch, let’s first talk about how to get rid of termites in mulch.

How To Get Rid Of Termites In Mulch

3 termites in mulch
Termites like mulch because it provides them with an ideal living space.

Before you begin treating your mulch for termites, it’s important to ensure you do indeed have termites in mulch.

First, inspect your mulch for these pests by digging up a small portion of the mulch. Look for signs of swarmer termites or worker termites.

Swarmer termites are black, long, and winged while worker termites are pale, ant-like insects with six legs and two antennae.

If you do see these pests, you can rest assured there are many more just out of sight. Termite tunnels can reach up to 20 feet below the surface, though this is not always the case. Luckily, you can use common termite killers and poisons to not only kill workers and swarmers near the surface but to eventually kill the entire colony below.

The best way to use products for how to get rid of termites in mulch is to invest in a product you trust.

Apply the termite killer to the mulch and then rake the mulch so the poison is mixed. We also suggest setting termite baits and traps.

Termite baits will ensure that the queen and young of the colony are eventually destroyed while traps will help you to monitor the termites in mulch as you go.

The process of getting rid of termites in mulch can be time-consuming, so while you are working to get rid of these pests in your yard or garden, it’s also a good idea to protect your home to keep termites from getting inside.

You can help get rid of termites in mulch by applying the mulch appropriately.

Getting rid of mulch doesn’t always mean you must purchase products or use chemicals. In fact, there are several home remedies and do-it-yourself pest control ingredients you can use to keep these pests from becoming a problem.

Borax Powder

Borax powder is a natural product that is commonly used around the home for cleaning purposes. It is also commonly used for doing laundry. Though borax can be an irritant to humans and pets, it is generally considered harmless.

Vinegar And Lemons

Vinegar works well when it comes to getting rid of termites in mulch. To use this method, combine half a cup of vinegar with the juice of two lemons (or 8 tablespoons of lemon juice). Add the mixture to a spray bottle and spray it around the mulch and near any termite mounds or entry points you notice. Repeat this method as often as you need to repel termites and encourage existing termites to leave.

Make Your Own Cardboard Termite Traps

Soak several pieces of cardboard with water and then place them in layers over the mulch. The cellulose in the cardboard will attract the termites below the surface of the mulch to the cardboard. You can collect the cardboard and dispose of it to kill termites as you go.

However, keep in mind that this cardboard trap for termites in mulch will only collect some of the termites and not kill the entire colony.

How To Manage And Prevent Termites In Mulch

Birds and other predators can help control termites in mulch.

The best way to manage termites in mulch is to use proactive measures to help prevent termites from getting out of control. There are several methods you can use to keep these pests at bay, but we have listed some of our expert recommendations below.

Use Insect Repellent Mulch

The best mulch you can use to repel termites and other insects includes cedar mulch, melaleuca mulch, cypress heartwood mulch, redwood mulch, and licorice mulch. Not only will these types of mulch repel termites and a variety of other pests like rodents, spiders, earwigs, slugs, and pillbugs, but these types of mulch also tend to last longer than other types of mulches you may use for your garden.

Use Alternatives To Mulch

Although the presence of mulch doesn’t necessarily attract pests, it can make an ideal habitat for them. This is especially true when it comes to termites. If you are looking at ways to get rid of termites in mulch, you might consider forgoing the use of mulch altogether.

Instead, consider using products that provide the same benefits as mulch without the pest-attractant properties.

Some of the best alternatives to mulch include:

  • Rocks or Gravel
  • Straw
  • Pine Needs
  • Rubber Mulch
  • Compost
  • Newspaper
  • And Grass Clippings

Keep Mulch Away From The Siding Of Your Home

If you do want to use mulch in your yard or garden, keep it at least six inches from the siding of your home. You can also create a barrier against the mulch and your home using pebbles or rocks, which will not provide the same ideal habitat to termites and other pests that mulch will.

Remove Excess Wood Debris On Your Property

Mulch doesn’t attract termites, but other wood debris does. The best way to keep termites at bay is to remove attractants like woodpiles, hollow trees, stumps, and other wood debris from around your home.

You might also consider using a sealant that protects your home and wood to keep it strong. Weakened wood beams and siding can become more attractive to termites, as it is easier for them to chew through.

Get Rid Of Excess Water Sources

Excess moisture can also be an attractant to termites, so removing excess water sources from around your home can keep termites at bay. Excess water sources could include leaky pipes or drainage. Homes or areas around the property that don’t have proper airflow could create moist environments that could also be attractive to termites, so keep this in mind.

Keep Up With Home Maintenance

Termites in mulch do not have to automatically mean termites in your home. In fact, you can proactively protect your home by ensuring you repair cracks, crevices, and other potential entry points that could give termites easy access.

Use A Year-Round Pest Control Product Or Regiment To Keep Termites Under Control

Termites can be costly and even dangerous pests, and termites in mulch can easily lead to termites inside your home. The best way to keep termites under control is to use a year-round pest control product or regiment in order to prevent them.

So, what do you think about getting rid of termites in mulch? Would you prefer to continue to use mulch in your yard and garden now that you know it’s not necessarily the mulch that attracts these insects?
