English lavender has long been touted as a natural mosquito repellent.
Research suggests that English lavender contains compounds that can repel mosquitoes, including linalool and linalyl acetate.
In a study, English lavender oil was found to repel mosquitoes for up to 4 hours.
The strong scent of English lavender can be overwhelming to mosquitoes, making it difficult for them to land and feed.

Natural Repellents
Lavender is a natural mosquito repellent that works by overwhelming their senses with its strong fragrance. It's a safer alternative to DEET, which can have potential health effects.
The U.S. Environmental Protection Agency (EPA) recognizes linalool, a terpene alcohol found in lavender, as an active ingredient to keep mosquitoes away while outside. Linalool is effective at repelling mosquitoes and has a low toxicity score of 3, according to the Environmental Working Group (EWG).
You can use lavender oil in combination with other natural repellents for immediate protection from mosquitoes. However, lavender is more effective at killing mosquitoes long term, with three times more mosquitoes dying after exposure to linalool in the 24 hours after they were exposed to the substance.
Planting lavender around your yard or patio can help kill off the mosquito population, making it a beautiful and effective addition to your garden landscape.

Planting and Care
Planting English lavender in well-draining soil is essential for its growth and effectiveness in repelling mosquitoes.
English lavender prefers full sun to partial shade, which is why it's best to plant it in a spot that receives at least 6 hours of direct sunlight per day.
To ensure the soil drains properly, mix in some organic matter like compost or perlite when planting.
Watering English lavender is a delicate balance, as it needs consistent moisture but can be susceptible to root rot if the soil is too wet.
English lavender typically requires watering once or twice a week, depending on weather conditions.
Fertilizing English lavender is not necessary, as it's a low-maintenance plant that can thrive in poor soil.
However, if you want to give your English lavender a boost, a balanced, water-soluble fertilizer can be applied in the spring.
Pruning English lavender in the spring helps to promote new growth and prevent it from becoming leggy.
Regular pruning also encourages the plant to produce more flowers, which are a key component in repelling mosquitoes.

Understanding Mosquitoes
Mosquitoes are incredibly resilient insects, with some species able to survive for up to 2 weeks without food or water.
They're attracted to the carbon dioxide we exhale, as well as the lactic acid and other chemicals present in our sweat.
Female mosquitoes are the primary biters, as they need the protein from blood to lay eggs.
Their tiny proboscis can pierce human skin with ease, making them a formidable foe.
Mosquitoes are most active during dawn and dusk, when the air is typically cooler and more humid.
In ideal conditions, a single female mosquito can lay up to 300 eggs at a time.
Repelling Indoors and Outdoors
Lavender is effective at repelling mosquitoes both indoors and outdoors.
Diffusing linalool indoors can repel mosquitoes by 93%, making it a great solution for a peaceful night's sleep.
You'll want to consult your veterinarian before using essential oils on or near your pets, as they can be toxic.
Using lavender oil in combination with other natural repellents is more effective for immediate protection from mosquitoes outdoors.
Planting lavender around your yard or patio can help kill off the mosquito population over time, even if it doesn't completely keep them away short term.
Repelling Indoors

Lavender is a natural mosquito repellent that can be used indoors, and it's surprisingly effective. In fact, a study in the Journal of Vector Ecology found that diffusing linalool indoors repelled mosquitoes by 93%.
You can try using lavender essential oil in a diffuser or vaporizer to keep mosquitoes at bay. Just be sure to consult your veterinarian before using essential oils on or near your pets, as they can be toxic to them.

If you're planning to repel mosquitoes outdoors, using lavender oil in combination with other natural repellants is a good idea, but it's not the most effective option for immediate protection.
Lavender oil's linalool component repelled female mosquitoes by 58% outside, but other natural oils like geraniol worked better, repelling up to 75%.
You can still kill off the mosquito population by planting lavender around your yard or patio, which is a beautiful addition to your garden landscape.

In fact, a study found that three times more mosquitoes died after exposure to linalool in the 24 hours after they were exposed to the substance.
Planting lavender seeds or buying lavender plants can instantly add protection from mosquitoes on your patio, in your garden, or on a balcony.
You'll still want to use a candle, spray, or other type of topical mosquito repellant using lavender oil in addition to other oils like citronella to have the best effect at keeping biting mosquitoes away.
