Long summer days, warm evenings on the terrace… and the inevitable hum of mosquitoes. In Spain, mosquito activity peaks from late spring to early autumn, particularly in humid coastal areas or near standing water. While sprays and nets are common defenses, there’s a greener, more sustainable solution: growing mosquito-repelling plants.
At Planteka, we help people reconnect with plants and nature through expert-led workshops, personalized Plant Doctor consultations, and practical content like this. While you embark on a journey to create your idyllic green home, we’re here to offer helpful plant care tips along the way.
In this guide, discover plants that thrive in Mediterranean climates and naturally keep mosquitoes (and other bugs) at bay.
Why use plants to repel mosquitoes?
Some plants produce natural compounds (like citronellal, limonene, or thymol) that deter insects. Their scents confuse mosquitoes or mask the human scents that attract them. Planted strategically, they can create a protective green barrier around patios, balconies, and gardens.
But remember: plants alone won’t eradicate mosquitoes—they complement other measures like removing standing water where mosquitoes breed.
6 mosquito-repelling plants for Mediterranean gardens
1. Lavender (Lavandula)
- What it is: A purple shrub with a calming scent native to the Mediterranean region
- Why it works: Lavender’s essential oils contain linalool and camphor, which repel mosquitoes, moths, and flies.
- How to care for it:
- Full sun (at least 6 hours/day)
- Water sparingly; very drought tolerant once established
- Prune after flowering to encourage new blooms and intensify the aroma
- Dried lavender bundles hung near doors or windows also act as a deterrent

3. Basil (Ocimum basilicum)

How to design a mosquito-repelling garden
- Place strategically: Arrange pots of mint, basil, and lavender around seating areas, windows, and doors.
- Combine heights: Use tall citronella grass or rosemary as a backdrop with marigolds and basil at lower levels.
- Think vertical: Hang dried lavender bundles near entryways.
- Prevent breeding: Eliminate standing water from saucers, buckets, or gutters.
