Top 10 Plants That Repel Bugs Around the Pool
If you’re looking for a natural way to keep bugs at bay, consider incorporating these effective, easy-to-grow plants into your poolside garden.
1. Citronella
Why It Works:
Citronella is widely known for its mosquito-repelling properties. It contains citronellal and geraniol, compounds that interfere with the receptors mosquitoes use to detect humans.
How to Plant:
Citronella thrives in full sun and well-drained soil. Since it’s a type of grass (often known as Cymbopogon), it can grow quite large, so ensure you give it enough space or plant it in pots.
Care Tips:
Water regularly but avoid waterlogging. Citronella can be grown indoors in colder climates and prefers temperatures above 55°F (13°C).
2. Lavender
Why It Works:
Lavender’s strong fragrance masks the scents that attract insects like mosquitoes and moths. It also contains linalool and linalyl acetate, which are proven to deter flies and mosquitoes.
How to Plant:
Plant lavender in sunny locations with well-drained, sandy soil. Avoid over-watering, as this herb prefers drier conditions.
Care Tips:
Lavender does not require fertilizer and actually thrives in poorer soils. Trim back after flowering to encourage growth and maintain shape.
3. Basil
Why It Works:
The strong essential oils in basil—linalool, estragole, and eucalyptol—are effective against mosquitoes, flies, and even thrips. It’s also an excellent edible herb to keep nearby.
How to Plant:
Grow basil in sunny spots with rich, moist soil. It can be planted directly in the ground or in pots near pool chairs or tables.
Care Tips:
Basil requires regular watering and should be protected in colder climates. Pinch leaves to encourage bushier growth and avoid letting it bolt.
4. Marigolds
Why It Works:
Marigolds produce pyrethrum, a compound used in many insect repellents and insecticides. They are effective against mosquitoes, aphids, and even nematodes in soil.
How to Plant:
Direct sow or start indoors and transplant after the last frost. Place near pool edges where sun exposure is generous.
Care Tips:
Marigolds are low maintenance and drought-tolerant once established. Deadhead spent flowers for continuous blooming.
5. Geranium
Why It Works:
Geraniums are particularly effective against mosquitoes and ticks. Their leaves and flowers emit a strong scent that bugs find unattractive.
How to Plant:
They can be grown from seeds, but most gardeners prefer purchased seedlings for quicker blooms. Full sun and fertile soil are ideal.
Care Tips:
Water at the base to avoid wetting the foliage, which can lead to mildew issues. Fertilize regularly for better performance.
6. Lemongrass
Why It Works:
Lemongrass is a natural cousin of citronella and has very similar essential oils. It’s particularly effective against mosquitoes and other flying pests.
How to Plant:
It requires full sun and moist soil. It can become invasive in some climates, so planting in containers near the pool is recommended.
Care Tips:
Trim the grass regularly to reduce spread. In colder areas, bring pots indoors during winter.
7. Mint
Why It Works:
Mint’s intense aroma deters spiders, ants, mosquitoes, and even mice. It’s easy to grow and has culinary uses as well, giving you a dual-purpose plant for your garden.
How to Plant:
Mint prefers partial to full sun and moist soil. Because it spreads aggressively, it is wise to grow it in pots or contained areas.
Care Tips:
Mint thrives in shady, damp locations. Water regularly and prune back any runners to contain its spread.
8. Catnip
Why It Works:
Nepetalactone, the compound that excites cats, happens to be highly deterrent to mosquitoes. Studies have shown it to be more effective than DEET in some instances.
How to Plant:
Catnip grows in sun or part shade and prefers well-draining soil. It’s a resilient plant, but it can self-seed aggressively.
Care Tips:
Keep catnip in check by removing spent flowers to prevent seeding. It’s drought-tolerant once established.
9. Rosemary
Why It Works:
Rosemary has been proven to deter mosquitoes when burned, crushed, or grown directly in gardens. Its aromatic oils make it difficult for insects to approach.
How to Plant:
It thrives in full sun and well-drained soil. It’s best grown in containers in cooler zones and can be used as a sculptural plant around decks and patios.
Care Tips:
Rosemary requires minimal watering and does well in coastal and dry climates. Avoid overwatering as root rot may occur.
10. Lemon Balm
Why It Works:
Lemon balm, like mint, contains citronella-like compounds. It’s a mosquito deterrent with a pleasant lemon scent when touched.
How to Plant:
Full sun or light shade is preferred, in well-draining soil. It spreads quickly, so planting in pots is wise.
Care Tips:
Regular pruning will help it stay bushy and healthy. It’s hardy and adapts well to different soils.
How to Strategically Place These Plants Around the Pool
Integrating bug-repelling plants around the pool isn’t just effective, it’s an opportunity to enhance garden layouts and aesthetics.

Planting in pots allows you to move plants as needed, preventing overgrowth and making it easy to care for species sensitive to water or cold exposure. Place containers strategically near lounge chairs, eating areas, or around the perimeter of the pool.
2. Plant in Sunny Spots
Most insect-repelling plants thrive in sunlight. Since pool areas are typically sunny, that’s a major advantage. Plan your garden beds or container spots according to the light requirements of each plant.
3. Cluster Aromatic Plants Near Sitting Areas
To enhance the bug-repelling effect, group strong-scented plants close to areas where people sit and relax. For example, basil and lemongrass can be grown on patios, while lavender and geraniums are perfect beside sun chairs.
4. Layer Taller and Shorter Plants for Coverage
Tall plants like citronella grass can be used as background plants, while shorter herbs like mint or catnip can be used as border plants. Layering maximizes coverage and visual appeal.
Maintaining a Bug-Repelling Garden Around the Pool
Just like any garden, maintaining a bug-repelling garden needs attention and care. Here are tips to help your natural pest control thrive:
Water Wisely
Too much standing water near the pool can attract insects like mosquitoes. Water the base of the plants and avoid creating puddles or wet puddling in saucers under pots.
Prune Frequently
Regular pruning of aromatic herbs like rosemary, lavender, and geranium keeps the plant vigorous and helps intensify their scent release.
Consider Companion Planting
Pair plants that repel different pests for better and more comprehensive natural repellency. For example, planting lavender with basil adds a multi-layer defense against both mosquitoes and flies.

What are the best natural bug repellent plants to grow around a pool?
Several plants naturally deter insects and can be effectively placed around a pool area. Among the top options are citronella grass, known for its strong mosquito-repelling scent; lavender, which repels moths, mosquitoes, and flies while adding a pleasant fragrance; and lemongrass, which has a citrusy aroma that many pests find unappealing. Marigolds are also a great choice, as they contain natural compounds like pyrethrum that discourage mosquitoes and other insects.
Additionally, basil, peppermint, and catnip have proven insect-repelling properties and can thrive in container gardens near pool decks. Rosemary is another excellent herb that, when burned, releases a fragrant smoke that repels mosquitoes. When planning your poolside garden, it’s important to select plants that are both effective at repelling bugs and suited to the climate and conditions around your pool area. Choosing non-toxic plants is also recommended if small children or pets frequent the space.
How do these plants help in keeping bugs away?
Many bug-repelling plants emit natural essential oils through their leaves and flowers that pests find unpleasant or confusing. These volatile compounds mask the scents that attract insects, such as carbon dioxide and lactic acid emitted by humans. For instance, citronella releases oils that disrupt mosquitoes’ ability to locate hosts, effectively reducing bites and irritation around the pool area.
In addition to their scent, some plants offer physical benefits such as repelling insects when touched or crushed. Examples like basil and catnip can be bruised slightly to release stronger aromas. When strategically placed near seating areas, entryways, and pool edges, these plants create a natural barrier that deters pests. Their use complements other eco-friendly bug control strategies like eliminating standing water and using fans or screens to further enhance comfort around the pool.
Can I grow pest-repelling plants in containers around my pool?
Yes, growing bug-repellent plants in containers is a highly effective and flexible option for poolside pest control. Potted plants can be placed on patios, ledges, and railings, making them easy to move depending on the season or the location of visitors. Container gardening also allows for better control over soil conditions and drainage, which is often important around concrete or paved pool decks.
Using attractive, weather-resistant pots helps maintain an appealing look while incorporating these plants into your poolside decor. Herbs like mint, basil, and rosemary grow readily in planters and can be kept close to lounging areas to enhance their repellent effect. It’s also wise to consider the mature size of each plant to ensure the containers are large enough and that the plants won’t become root-bound. This method also prevents invasive species like mint from overtaking your garden or landscape.
Are natural bug repellents safer than chemical sprays?
Natural bug repellents, including insect-repelling plants, are generally considered safer for people, pets, and the environment compared to chemical sprays. Many commercial insecticides contain synthetic compounds like DEET or permethrin, which can cause skin irritation or adverse reactions in sensitive individuals. Using plants instead helps reduce exposure to these chemicals, especially in places like pool areas where children and pets play.
However, it’s important to note that while natural methods are generally safer, they may not be as potent or long-lasting as synthetic repellents. Their effectiveness often depends on proper placement and usage, such as crushing leaves to release essential oils. For optimal protection, a layered approach—combining plants with other eco-friendly options like citronella candles or fans—can provide both safety and enhanced pest deterrence around the pool.
Do the repellent plants require special maintenance around a pool?
Most bug-repelling plants are easy to maintain and can thrive around pools if their basic needs are met. Sunlight is critical for many, such as lavender and rosemary, which require full sun for optimal growth. Proper watering is also important, although poolside plants may receive frequent splashes or runoff, so care should be taken to avoid waterlogged roots.
Some plants, like citronella grass and lemongrass, may require more frequent watering and nutrient-rich soil. Planting in well-draining pots or raised beds can help mitigate soil saturation. Additionally, regular pruning not only encourages healthy growth but also helps release volatile oils that enhance their bug-repelling properties. Choosing native or climate-appropriate species also reduces maintenance efforts and contributes to long-term plant resilience around the pool area.
Can these plants be used indoors as well for bug control?
Yes, many of the plants that repel bugs outdoors can also be effective when used indoors, especially near windows, patios, or sunrooms. Plants like basil, mint, and catnip can be placed in kitchen windowsills or on indoor tables and still help deter flies and mosquitoes. This dual-purpose use allows for both ornamental and functional value throughout the home.
However, indoor environments may provide fewer opportunities for plants to naturally disperse their scents. In such settings, using the plants more deliberately—for instance, crushing leaves occasionally or distilling essential oils into diffusers—can increase their effectiveness. Ensuring adequate light, humidity, and proper watering for indoor conditions will also help maintain the plants’ health and potency as natural insect detergents.
Can using plants for pest control complement other natural repellent methods?
Integrating repellent plants with other natural methods can drastically improve the efficacy of your pest management strategy around the pool. Pairing these plants with citronella candles, fans, or even water features that deter pests can create multiple layers of defense without resorting to harsh chemicals. Fans, for example, can help spread the aromatic oils from plants while also making it harder for mosquitoes to fly.
Additionally, combining plants with physical pest control strategies—such as eliminating standing water where mosquitoes breed—enhances the overall impact. Natural repellent sprays made from plant extracts like peppermint or lavender can also be used on skin or surfaces to supplement the presence of the living plants. Together, these strategies provide a comprehensive, environmentally friendly approach to controlling pests and creating a more enjoyable outdoor pool environment.
