Do Ants Like Lavender? No – Here's Why It Repels Them

By James Wilson · January 23, 2026

Do Ants Like Lavender? Direct Answer

No, ants do not like lavender. In fact, the strong aromatic oils in lavender, especially linalool and camphor, act as natural ant repellents. Planting lavender around your garden or using lavender essential oil can help deter ants from invading your space.

Why Ants Avoid Lavender

Lavender (Lavandula spp.) produces a distinct fragrance due to its high concentration of essential oils. These compounds interfere with ants’ sensory receptors and disrupt their pheromone trails, making it difficult for them to navigate.

Key Compounds in Lavender That Repel Ants

Linalool: A terpene alcohol that disrupts insect nervous systems.
Camphor: Creates a strong odor ants find unpleasant.
Lavandulyl acetate: Contributes to scent complexity, confusing insect communication.

Scientific Evidence: Lavender vs. Ants

Multiple studies have evaluated the effectiveness of lavender essential oil as an insect repellent. The results consistently show significant ant-deterrent effects when exposed to concentrated or planted forms of lavender.

Study	Essential Oil Used	Ant Species Tested	Repellency Rate (%)	Duration of Effect
Ali et al., 2023	Lavender (Lavandula angustifolia)	Solenopsis invicta (Fire ant)	87%	Up to 4 hours
Zhang & Liu, 2022	Lavender essential oil	Linepithema humile (Argentine ant)	76%	3.5 hours
University of Florida IFAS, 2024	Diluted lavender oil spray	Various household ants	82%	2–3 hours
Gupta et al., 2023	Fresh lavender plant proximity	Tetramorium caespitum (Pavement ant)	70%	Ongoing (live plants)

Table data source:1, 2, 3

The data shows that lavender essential oil achieves over 70% repellency across multiple ant species, with effects lasting several hours. Live lavender plants also provide sustained, moderate protection by altering local microclimate and scent profiles.

Using Lavender to Keep Ants Away

There are several effective ways to use lavender as a natural ant deterrent:

1. Plant Lavender Near Entry Points

Grow lavender near doors, windows, or foundation walls where ants typically enter. The continuous release of essential oils creates a passive barrier.

2. Use Lavender Essential Oil Spray

Mix 10–15 drops of lavender essential oil with water and a few drops of dish soap in a spray bottle. Apply along ant trails, baseboards, and cracks.

3. Place Dried Lavender Sachets Indoors

Dry lavender bundles or sachets placed in cabinets, pantries, or drawers repel ants while adding a pleasant scent.

4. Combine with Other Repellent Plants

Pair lavender with rosemary, mint, or marigolds for enhanced pest-deterrent landscaping.

Common Myths About Lavender and Ants

Myth: All insects hate lavender.
Truth: While many pests avoid it, pollinators like bees and butterflies are attracted to lavender.
Myth: Any lavender variety works the same.
Truth: Lavandula angustifolia and L. intermedia have higher oil concentrations and better repellency.
Myth: One-time application eliminates ants forever.
Truth: Regular reapplication or live planting is needed for lasting results.

Frequently Asked Questions About Ants and Lavender

Does planting lavender keep ants away?

Yes, planting lavender can help keep ants away due to its strong essential oils that disrupt ant navigation and communication. It works best when planted near common entry points.

Will lavender essential oil kill ants?

Lavender essential oil does not usually kill ants on contact but acts as a powerful repellent. For killing, combine it with soapy water or other natural insecticides.

What type of lavender repels ants most effectively?

Lavandula angustifolia and Lavandula x intermedia are most effective due to higher concentrations of linalool and camphor, which ants strongly dislike.

How often should I reapply lavender spray?

Reapply lavender spray every 2–3 days or after rain if used outdoors. Indoors, weekly application is sufficient for maintenance-level repellency.

Are there any ants that like lavender?

No known ant species are attracted to lavender. While they may cross through temporarily, prolonged exposure causes avoidance behavior due to olfactory disruption.
