Does Lavender Work to Repel Mosquitos?

Yes. A few studies have been conducted that show that lavender is quite effective at repelling mosquitos. A 2009 study¹ on the lavender plant’s ability to repel mosquitos found it capable of reducing numbers by as much as 53% when you grow them outside around the house. Results are even better indoors, and you can expect a 93% reduction in numbers when you have lavender indoors. Another study¹ in 2019 found that the essential oil from the lavender plant can reduce mosquitos in the area by up to 80%.

Lavender Essential Oil

Lavender essential oil can reduce mosquitos in your area by up to 80%, and you can take it with you if you are traveling, so you are never vulnerable.

DIY Lavender Essential Oil Spray

Is Lavender Essential Oil Safe for Pets?

The lavender plant is not toxic to pets, but the essential oil is much more concentrated and can cause health problems for cats, dogs, and horses. If you need to use essential oils to eliminate mosquitos, make sure you only use them outdoors, where your pets can’t get any of the oils on their skin or paws.

Are There Other Plants That Can Help Reduce Mosquito Populations?

Yes, besides lavender, there are quite a few plants that you can put in your garden or around your property that will work well to reduce the number of mosquitos that you encounter. These include basil, citronella, mint, thyme, catnip, and marigold.

Lavender repels mosquitos quite well, and planting it around your property can help bring significant relief. It’s easy to grow outside and you can even grow it indoors. The lavender essential oil works even better, and you can find it in many forms, from pure oil to soaps and creams. The only downside to the essential oil is that it can harm your pets, especially if they get it on their skin, so you will need to keep it out of reach and use it only outdoors.
