How to Control Termites in the Garden

By Greg Lindberg ; Updated September 21, 2017

Termites often find their way into a garden after they’ve nested in your home or a nearby tree. A food source is most likely attracting the pests if you notice an infestation of termites in your garden. Termites feed on cellulose, which is found in woody plants, decaying wood and moist bark mulch. It’s important to also begin the appropriate actions to prevent the termites from entering your home when you begin controlling the termites from entering your garden.

Locate where the termites are coming from. Look for any piles of decaying logs or mud nests on trees nearby.

Using a pyrethrum pesticide, spray any visible termites in or around your garden. Make sure you are a least 5 feet from your garden when spraying so that you don’t affect any of your flowers or crops.

Reduce the moisture in your garden’s soil and near the exterior of your house, as termites are attracted to moist soil. Turn off any leaking spigots near the area and make sure you don’t over-water the soil in your garden.

Remove woodpiles that are too close to your garden and place them as far out in your property as possible. Also, make sure that wood or mulch doesn’t barricade the exterior of your house.

Make a barrier around your house using 16-grit sand. Create a bed of rock between your house and garden to help prevent any termites from returning.

Contact your local nursery about using nematodes if the problem persists. Nematodes are tiny bugs that will eat insects like termites and are safe for your plants. They will often come in a sprayer and are applied to the termite-infested areas.
