How to Make a Natural Mosquito Repellent

Kenneth Wilson

When I first moved to the Sunshine State, I was excited about the temperate weather all year long. Spending time outdoors under the Florida sun is a great way to relax and enjoy most afternoons. 

Unfortunately, it’s not only us who enjoy this weather. Mosquitoes thrive in our climate and we all know how a swarm of these pesky bugs can send us running in our homes. Good thing that there are many ways you can get rid of these mosquitoes and one of the most popular methods is using a DEET-based chemical repellent.

But not everyone wants to use DEET products since it has the potential to harm their health and the environment. That’s why some people opt for natural methods. Aside from being safer for you and your surroundings, it is also inexpensive to make. 

Continue reading to find out if they really work, what ingredients mosquitoes hate, and learn how to create natural mosquito repellents.

Do natural repellents really work?

Yes...but it depends.

Entomologist Water Leal of the University of California, Davis mentioned that natural mosquito repellents work but there is one major problem. This type of repellent doesn’t last long enough. It doesn’t have a complete protection time, meaning it only works for a short period. 

Compared to DEET, which is a common chemical found in the most effective repellents, DEET products will work effectively and for a longer time. It’s great at repelling mosquitoes as this chemical prevents them from smelling our breath and sweat, which is attractive to these pesky bugs.

So if you don’t reapply natural mosquito produce frequently, then it won’t be effective. But the good news is that if you will only be outside for a short time, you can use citronella repellent and other natural products with citral, eugenol, geraniol, and linalool. If you will stay outdoors for more than one hour, then you should opt for a DEET product. 

Another time you should apply DEET products is when you’re visiting a place or country that contains mosquitoes carrying any disease. This means if there’s a high risk of contracting mosquito-borne diseases like West Nile Virus and Zika, it’s best to use DEET mosquito repellents. 

But if you’re going to relax outdoors, go on a camping trip, or take a hike, then you can use natural mosquito repellents - as long as you re-apply often! It’s also safer for those who are sensitive to chemicals found in some products.

Note: You will probably need to experiment with natural mosquito repellents that will work best against the species found in your home as the effectiveness of certain ingredients varies between species.

Natural ingredients that mosquitoes hate

There are some chemicals found in bug sprays that can get rid of mosquitoes, but unfortunately, natural ingredients won’t be effective in this area. We may not be able to kill mosquitoes using chemical-free products but we can repel them with these natural ingredients:


You’re probably already familiar with this ingredient as it is one of the most commonly found ingredients in natural mosquito repellents. When mixed with herbs, this essential oil is effective against mosquitoes. If it is not formulated correctly, it won’t be effective as it will evaporate quickly. You will need the right formulation for this to be as effective as DEET and provide protection for up to two hours.  You may also use citronella candles but they only offer 50% protection. 


This an ingredient derived from plant oils like lemongrass, rose, and citronella. It is a type of alcohol also used to add flavor and fragrance. It is an effective mosquito repellent but it depends on the species. Unlike other natural ingredients, this one should be avoided by people with sensitive skin and kept away the eyes as it may cause skin and eye irritation.


If you happen to have lavender flowers, crushing these will produce a fragrance that mosquitoes hate. One study shows adult mosquitoes didn’t feast on hairless mice that have lavender oil on them. This also shows that even the product is safe to use for animals. It’s also great for calming and soothing the skin since lavender has antifungal, antiseptic, and analgesic properties.

Tea Tree Oil

Also called melaleuca oil, this is a popular ingredient that originated from Australia. Similar to lavender, it also has antiseptic qualities, as well as anti-inflammatory and antimicrobial. Recently, they found that tea tree oil can also be used to repel mosquitoes. It is also effective against biting midges and bush flies.

Lemon Eucalyptus Oil

This one is a popular ingredient found in natural mosquito repellents and has been used since the 1940s. It contains an active ingredient called Menthoglycol, which is comparable to the effectiveness of DEET. Despite the name, this is not a blend of eucalyptus oil and lemon but an ingredient extracted from the Corymbia citriodora tree.

Lemon eucalyptus oil is also considered effective by the Centers for Disease Control and Prevention (CDC). A study shows that a repellent containing 32% of this ingredient provides more than 95% protection for three hours.

Cinnamon Oil

You don’t have to look for this ingredient because chances are, you have cinnamon in your home. Who doesn’t love to top their desserts or snacks with cinnamon? Mosquitoes, specifically Asian tiger mosquitoes, hate this ingredient. There was also a Taiwanese study that shows cinnamon oil can be used to kill mosquito eggs. It’s time to kill these pests at the source!

Thyme Oil

Another effective ingredient against mosquitoes, even malarial ones, is thyme oil. One study shows that after applying 5% of this ingredient on hairless mice, it resulted in a 91% protection rate. Aside from a direct application on the skin,  you can also burn thyme leaves as it can provide 85% protection for an hour up to an hour and a half.

Soybean Oil

If you know the organic insect repeller Bite Blocker For Kids, this product contains 2% soybean oil. Based on a study from the University of Florida Medical Entomology Laboratory, repellents containing soybean oil can protect us from mosquitoes for a long time.

Greek Catnip Oil

Mint is great at warding off mosquitoes. One member of the mint family that is effective at repelling is Nepeta parnassica, the source of greek catnip oil. This white and pink flower is related to catnip and can grow up to 18 inches. To make use of it, you need to extract the oil from its bruised leaves. Research shows that this oil is effective against mosquitoes for two to three hours. There’s also a study conducted by researchers at Iowa State University who found that catnip is 10 times more effective than DEET.

Neem Oil

This natural ingredient can also be used to repel but the results aren’t consistent. One study showed that it only provided 70% protection for three hours in Ethiopia. Mosquito repellents with neem oil aren’t approved to be used on the skin as it may cause irritation.

Before using natural mosquito repellents: 

  • There’s a chance of getting an allergic reaction from any of these ingredients. Test the natural mosquito repellent on a small area of skin before applying it all over your body. Wait for an hour or two and if you don’t feel any burning sensation, get hives, rashes, or other bad reactions, you can use the product.
  • Since essential oils are not regulated by the Food and Drug Administration (FDA), make sure to buy from a reputable source.
  • These ingredients, especially essential oils should never be applied directly. It should always be diluted or mixed with a carrier oil such as almond oil with a ratio of 3 to 5 drops of essential in an ounce of carrier oil. 
  • Opt for chemical mosquito repellents if you are going to a place or location with mosquitoes carrying diseases to lessen the risk of contracting an illness.
