Nothing kills an evening on the patio faster than the high-pitched whine of a mosquito near your ear. Insect repellent sprays work, but they coat your skin in DEET and wash off the moment you start sweating. The smarter, longer-lasting approach is to surround your outdoor living spaces with living plants that naturally deter these pests. Specific botanical species release essential oils and aromatic compounds through their leaves — citronellal, linalool, geraniol — that mask the carbon dioxide and lactic acid signals bugs use to track you.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is the result of cross-referencing botanical hardiness data, essential oil concentration studies, and aggregated owner experiences across five different growing zones to identify which live plants actually deliver measurable insect-repelling results.
Whether you have a sprawling garden or a small balcony, the right selection creates a fragrant, chemical-free barrier that keeps biting insects at bay. Here is my analysis of the best plants to repel bugs currently available as live, ready-to-plant specimens.
How To Choose The Best Plants To Repel Bugs
Not every plant sold as a mosquito deterrent works equally well. The key is understanding which species produce high concentrations of the essential oils that actually interfere with insect olfactory receptors. Citronella grass (Cymbopogon nardus) and true lemongrass (Cymbopogon citratus) are the heavy hitters because their stalks and leaves contain up to 80% citronellal by volume. Citronella-scented geraniums (Pelargonium citrosum) release a lighter fragrance and are better suited to container placement near seating areas rather than as a perimeter barrier.
Growth Habit and Mature Size
Sprawling species like lantana act as a dense ground-cover barrier that crowds out weeds and releases repellent compounds across a wide footprint. Clumping grasses such as lemongrass grow vertically to 3–5 feet and work best when planted in a row along pathways or deck edges. Citronella geraniums top out around 24 inches, making them ideal for pots on a patio table where you can brush the leaves to activate the scent. Match the plant’s mature dimensions to your available space so the repellent effect covers the area you actually use.
Sun and Water Requirements
Essential oil production is directly tied to photosynthesis. Every plant on this list demands at least six hours of full sun per day to maintain high oil concentrations in its leaves. Partial shade reduces fragrance output by roughly 30–40%, diminishing the repellent effect. Moisture needs vary: lemongrass and lantana tolerate moderate watering once established, while citronella geraniums prefer well-drained soil that dries slightly between waterings. Overwatering dilutes the essential oils and encourages fungal issues.

In‑Depth Reviews
1. 8 Rooted Lemongrass Stalks 5-6 inches Long
This pack gives you eight individual stalks, each already rooted and measuring 5–6 inches at shipping. The lemongrass is grown using an advanced hydroponic system, which means the root systems arrive free of soil-borne pathogens and are ready to transition into peat soil or standard garden beds without shock. Multiple verified buyers in Zone 8b reported full-size plants by the end of their first growing season, and several noted the stalks returned the following spring after winter dieback was cut back in January.
The citronellal concentration in true lemongrass is significantly higher than in citronella-scented geraniums, making this a superior choice for a passive perimeter barrier around walkways, decks, and patios. One reviewer planted these specifically to repel wasps and confirmed the strategy worked. The stalks multiply over time through division, so eight plants can become a substantial clump within two seasons.
A caution: shipping times and packaging consistency vary. One buyer received stalks with brown roots and only a fraction survived, though the majority of reviews describe healthy, green arrivals. The failure rate appears linked to delivery delays rather than the nursery itself. If roots appear distressed, the seller recommends placing the stalk in room-temperature water for several days before planting.
What works
- Eight stalks provide dense, fast-growing coverage
- Hydroponic cultivation minimizes root disease risk
- High citronellal content for real mosquito deterrence
What doesn’t
- Root condition is inconsistent across different shipments
- No seller contact available after 31-day window
2. Clovers Garden Lantana Camara Flowers – Two Live Plants
Lantana works differently than lemongrass. Instead of releasing a strong aromatic oil, it produces compounds in its foliage that interfere with mosquito host-seeking behavior while simultaneously attracting beneficial pollinators like butterflies and hummingbirds. This two-pack from Clovers Garden ships as live plants in 4-inch pots, each measuring 4–8 inches tall at delivery, with a 10x root development claim that supports faster ground establishment.
The plants are grown in the Midwest using non-GMO, neonicotinoid-free methods and perform as tender annuals in Zones 9 and colder. Buyers in South Florida reported they flower quickly and thrive in full sun with regular watering. The sprawling growth habit makes lantana effective as a ground-level barrier that fills gaps between taller plants, reducing the sheltered spaces where mosquitoes rest during the day.
Packaging consistently earns high marks — one experienced online plant buyer ranked it in the top three deliveries they had ever received. A minority of reviewers noted slow initial growth and lack of flower buds, but those plants responded to a bloom-booster fertilizer. A single extreme negative review cited dead plants, though that experience appears anomalous among the broader feedback.
What works
- Excellent packaging preserves plant condition during transit
- Non-GMO and neonicotinoid-free growing method
- Attracts beneficial pollinators while repelling pests
What doesn’t
- Some plants arrive without visible flower buds
- Needs full sun and regular watering to thrive
3. CitronellaKing 2 Citronella (Mosquito Plant) – Pelargonium citrosum
True Pelargonium citrosum — often called the mosquito plant — produces a subtle citrus aroma from its serrated green leaves and occasional pink blossoms. This two-pack from CitronellaKing ships as fully rooted specimens in 4-inch nursery pots, with each plant reaching a minimum of 6 inches from stem base to tip at arrival. The plants are GMO-free and classified as deer resistant, making them suitable for suburban yards where browsing animals are a secondary concern.
Buyers consistently praise the shipping quality. Each plant is individually wrapped in protective casing, and the majority of reviews describe healthy, vibrant arrivals with immediate new growth after transplanting. One user confirmed that placing these on a back porch noticeably reduced mosquito presence. The growth habit is upright and bushy, topping out around 18–24 inches, which makes this a strong candidate for container placement near seating areas rather than in-ground perimeter planting.
A few buyers received specimens with dead leaves or dirt leakage during transit, and the flower count can be lower than the listing photos suggest. The fragrance is present but milder than true lemongrass — you need to brush the leaves to release the full aroma. For a patio accent plant with dual air-purifying and pest-deterrent claims, this delivers solid performance within its size class.
What works
- Excellent packaging with individual plant protection
- Deer resistant and attracts pollinators
- Transitions well between indoor and outdoor containers
What doesn’t
- Fragrance is milder than lemongrass varieties
- Occasional dead leaves or dirt spillage during shipping
4. THAIPHOON JIRA 5 Lemongrass Plants – 12 Inches Long
If you want the largest, most established lemongrass specimens available as live plants, this five-pack from THAIPHOON JIRA delivers stalks that are a full 12 inches long at shipping — roughly double the size of the first product. Each stalk is hydroponically cultivated to be free of soil contaminants, and the packaging is designed to protect the root mass during transit. One verified buyer received six stalks instead of five, and multiple reviews confirm the roots arrived well-established with visible new growth already emerging.
The dual-purpose value here is exceptional. Beyond the mosquito-repelling citronellal content, these stalks are thick enough for culinary use — a reviewer in Zone 7 successfully used them for Southeast Asian cooking and reported abundant yields from two 25-gallon pots. The plants thrive in full sun, and the seller notes that if roots detach during shipping, placing the stalk in room-temperature water for five days with daily changes will regenerate root development.
The cost per plant is higher than the shorter-stalk pack, but the size advantage means faster establishment and earlier repellent coverage. One buyer described the experience as a rare positive encounter for live plant online ordering. The low-maintenance care requirements apply whether you plant these in ground or in pots, and they are well suited for indoor overwintering in colder zones.
What works
- 12-inch stalks are significantly larger than standard offerings
- Dual use for repellent barrier and culinary applications
- Hydroponic cultivation reduces soil-borne disease risk
What doesn’t
- Higher per-stalk cost than shorter alternatives
- Requires full sun for maximum flavor and oil content
5. Soil Sunrise Live Citronella Geranium Plants (6-Pack)
This six-pack of citronella-scented geraniums from Soil Sunrise is built for quantity and small-space gardening. Each plant arrives in a nursery pot with a bushy, upright growth habit that reaches approximately 24 inches tall and 12–18 inches wide at maturity. The plants are GMO-free and come with a care and feeding guide to support establishment. The scent is unmistakably citronella — one reviewer noted that brushing a single leaf releases a strong aroma they found almost overwhelming.
Buyer experiences split on initial condition. Several plants arrived dry and wilted, likely due to shipping delays, but perked up within 24 hours after watering. A single negative review described the plants as junk, though the majority found them healthy and vigorous after a brief recovery period. The plants that survived transit have more than doubled in size within weeks, suggesting good genetic stock beneath the surface.
These geraniums work best as container plants on patios or balconies where you can rub the leaves to activate the scent. They are not as potent as true lemongrass for wide-area perimeter defense, but the six-plant count lets you scatter multiple pots across a seating area for distributed coverage. The summer blooming period adds visual appeal, and the compact size means they fit on railings, tables, or window boxes.
What works
- Six plants provide good coverage for small patios
- Powerful citronella scent when leaves are brushed
- Compact, bushy form fits containers and small spaces
What doesn’t
- Several arrivals reported dry, wilted plants
- Less potent as a passive barrier than lemongrass
Hardware & Specs Guide
Citronellal Content Per Species
The primary repellent compound in these plants is citronellal, a monoterpenoid aldehyde that masks human scent to mosquitoes. True lemongrass (Cymbopogon citratus) contains 75–85% citronellal in its essential oil. Citronella grass (Cymbopogon nardus) contains 10–40%, while citronella geraniums (Pelargonium citrosum) have less than 1%. If maximum passive repellency is your goal, lemongrass is the clear winner. Lantana works through a different mechanism — it produces compounds that disrupt mosquito host-seeking behavior rather than overwhelming their scent receptors.
Root System Readiness
Hydroponically grown plants arrive with bare roots, which are more vulnerable to drying out during shipping than plants shipped in nursery pots with soil. The 8-stalk lemongrass pack and the THAIPHOON JIRA 5-pack are hydroponic. Clovers Garden lantana, CitronellaKing geraniums, and Soil Sunrise geraniums all ship in 4-inch nursery pots with soil intact. Potted plants tolerate longer shipping times better, while hydroponic specimens offer faster soil adaptation and zero risk of soil-borne disease transfer.
