Winter Special: General Pest Control Starting at $99 & FREE Termite Inspection
Written by: Amador Cortez, CEO & Owner of Bellas Exterminator
Termites cause billions of dollars in property damage every year in the U.S. So it makes sense to look for every edge — including natural scents that might keep them away.
If you searched for “what smell do termites hate,” you are probably hoping for a simple, chemical-free way to protect your home. There are real answers. There are also some honest caveats.
This guide covers the scents termites hate most. You will see how to use them at home. We will also be clear about where natural repellents stop working and pro treatment starts.
Termites are repelled by strong natural scents. The most effective ones include cedarwood oil, tea tree oil, clove oil, orange oil (d-limonene), cinnamon oil, and garlic. These scents disrupt the pheromone signals termites use to communicate and find food. You can mix a few drops of essential oil with water and spray along baseboards, wooden surfaces, and cracks. Natural scents only work as a mild preventive measure — they cannot remove an active termite colony inside your walls. A professional inspection is the safest first step if you suspect termites.

Several plant-based oils are known to push termites away. Each one works through a different active compound.
| Scent | Active Compound | How It Works |
|---|---|---|
| Cedarwood oil | Allelochemicals | Termites avoid the scent and surface |
| Tea tree oil | Terpinen-4-ol | Strong aromatic repellent |
| Clove oil | Eugenol | Disrupts pheromone signals |
| Orange oil | D-limonene | Dissolves termite exoskeletons on contact |
| Cinnamon oil | Cinnamaldehyde | Neurotoxic effect on termites |
| Garlic | Sulfur compounds | Termites find it irritating |
| Lemongrass | Citral, geraniol | Acts as a scent repellent |
Termites do not have noses. They use antennae to read pheromone trails left by other termites. These chemical trails guide them to food and back to the colony.
Strong scents can disrupt this signal. The queen also releases pheromones that guide colony behavior. Outside scents do not reach her in the nest.
This is why oils deter but do not eliminate. They confuse single termites at the surface. They do not collapse the colony inside the wood.
We sometimes see homeowners who have sprayed essential oils around baseboards for months. The termites simply reroute to another entry point.
If you want to add a natural layer of defense, here is a simple way to do it.

Scents are preventive, not curative. They cannot reach termites inside the wood.
Glendora homes near the San Gabriel foothills face higher risk. Both subterranean and drywood termites are common in our area. Older wood framing makes a tasty target.
Pro treatment options include:
A free inspection tells you what is actually happening inside your walls.
Many of the Glendora homes we inspect have older wood framing that termites love. By the time owners notice signs, the colony is well established. Early inspection is everything.

These steps reduce the chance termites pick your home as their next meal.

We offer free termite inspections because catching termites early saves homeowners thousands in repairs.

Termites are most repelled by cedarwood oil, clove oil, and orange oil (d-limonene). These three consistently show the strongest deterrent effect because they either disrupt termite pheromone communication or damage their exoskeletons on contact.
Most essential oils repel termites rather than kill them. Orange oil (d-limonene) is the exception — it can dissolve termite exoskeletons on direct contact, but it only reaches termites at the surface. It will not eliminate a colony hidden inside walls or wood framing.
No. Natural scents are a useful preventive layer, but they cannot remove an active termite colony. Once termites are inside your wood, you need professional treatment such as a liquid barrier, baiting system, or fumigation.
Mix 5–10 drops of cedarwood, clove, or tea tree oil per gallon of water in a spray bottle. Spray baseboards, cracks, wooden frames, and crawlspace entries. Reapply every 1–2 weeks since essential oils evaporate quickly. Test on a small area first to avoid stains.
Yes. Homes near the San Gabriel foothills face higher termite pressure, including both subterranean and drywood termites. Older wood framing common in Glendora is especially attractive to termite colonies, which is why annual inspections are recommended.
Call a pro if you see mud tubes, discarded wings, hollow-sounding wood, frass (termite droppings), or any visible damage. Natural scents work as prevention only. Bellas Exterminator offers free termite inspections in Glendora to confirm what is happening before you spend on treatment.
