Living in Minnesota’s north woods, mosquitoes are quite literally our state bird. Itโs a DAILY battle not to be eaten alive from spring to fall. I grew up using the typical DEET mosquito spray and thought nothing of it until I started to pay attention to the after-effects.
The plants near my spray site nearly DIED. Their leaves developed bleached-out portions anywhere that DEET touched them. My lips would go numb if it came in contact with my face. It damaged materials like leather, plastic, and painted surfaces.
Oh boy. If thatโs happening to the stuff around me, what is DEET doing to MY skin and body?! The skin is an effective barrier to our outside environment but is also penetratable to certain substances, including DEET.
Not only is DEET able to be absorbed into our bodies, but only 50% of it is excreted over a span of 5 days. So, it sticks around in our bodies for A LONG time. No, thank you!
Of course, the EPA claims that DEET has โno risks of concern to human health or the environment,โ but what do other sources say?
- Exposure to 4 g of DEET weekly can lead to neurotoxicity
- DEET has potential carcinogenic properties
- High use can lead to seizures and Gulf War Syndrome
- The CDC says the risk is low, but later admits that high use can lead to seizures, uncoordinated movements, agitation, aggressive behavior, low blood pressure, and skin irritation
- DEET is making its way into our natural waterways and drinking water, largely from showering it off or excreting it from our bodies.
While the negative effects of DEET are largely tied to high doses and it has undoubtedly saved lives in terms of Malaria, West Nile Virus, etcโฆ. is there another way?
Of course, there is! Essential oils are fairly effective as long as the right ones are selected and dosed at the proper concentration. Letโs dive in!
The Best Essential Oils to Repel Mosquitos
While DEET is undoubtedly the most effective compound at repelling mosquitos, Iโve found my homemade essential oil mosquito repellent works well enough in 95% of situations. Itโs pleasant to use and has greatly reduced my overall DEET exposure.
When I do happen to get a few bites, a quick application of my Chickweed Salve soothes them right away!
Essential oils to repel mosquitoes:
- Camphor
- Cedarwood – weak evidence to support its use (Barnard, 1999)
- Citronella – One of the most effective essential oils (Trongtokit, 2005), but can wear off within 30 minutes.
- Clove – One of the most effective essential oils (Trongtokit, 2005; Barnard, 1999). Also has the longest duration of repellency.
- Eucalyptus
- Geranium – shows similar effectiveness to DEET (Ali, 2013)
- Lavender
- Lemon
- Lemongrass
- Patchouli – One of the most effective essential oils (Trongtokit, 2005)
- Peppermint – Only effective in high concentrations (Barnard, 1999).
- Pine needle
- Rosemary
- Thyme – One of the most effective essential oils (Barnard, 1999).
Homemade Mosquito Repellent Recipe
This recipe provides a 2% dilution, which is ideal for topical application. It’s fine to omit or add other essential oils. You may not have all of these on hand, or you may want to experiment with others such as eucalyptus or rosemary! Just be sure to keep the total to 50 drops for the 4 oz recipe to prevent skin irritation.

Supplies
- Measuring cup
- 4 oz spray bottle– I like amber glass since I often have this bottle outdoors with me (UV light will rapidly degrade the essential oils)
Ingredients
- 4 oz Distilled water
- 5 drops Patchouli essential oil
- 5 drops Clove essential oil
- 10 drops Geranium essential oil
- 10 drops Citronella essential oil
- 10 drops Lemongrass essential oil
- 10 drops Lavender essential oil (optional: substitute Thyme essential oil for extra strength!)
- 50 drops Polysorbate 20 – an essential emulsifier
*Be sure to use an essential oil brand that is unadulterated and therapeutic grade. What I have linked above is (based on my research) the best quality, affordable, and accessible. I’m slowly transitioning over to them as my previous supply runs out.
**There is some research to support that vanillin (the main compound in vanilla) can extend the time that essential oils are effective in repelling mosquitos – up to 3 hours! While I haven’t personally tried it, it might be worth experimenting with. I’d start by adding 1 tsp of REAL vanilla extract into the mixture above.
How to make it
Step 1: Mix together
Once you have your ingredients gathered, the rest is super easy! Fill the spray bottle with 4 oz of distilled water, then add the 50 drops of Polysorbate 20, followed by the 50 drops of assorted essential oils. As discussed above, it’s okay to do some swapping of the essential oils as long as you stick with 50 drops in total for the 4 oz recipe.
Step 2: Shake well
Before you use it, shake the mixture well to ensure that all of the essential oils are well-incorporated and you receive a true 2% dilution when sprayed onto your skin. The Polysorbate 20 is a great emulsifier to get the oils and water to mix properly, but it won’t hold the solution in suspension forever, so be sure to shake it before each application.
Step 3: Label
I know what you’re thinking “Oh, I’ll remember what this is.” Trust me, you won’t! Always, always label your homemade goods with at least the name of what it is and the date you prepared it. If there’s room, I like to list out the ingredients as well. You can use cute labels, or if you’re basic like me, a strip of masking tape works just fine.
Putting My Homemade Mosquito Repellent In Action
How to use
Simply, give it a shake and then mist a light layer over your skin and clothing. Avoid your eyes and mouth. Start with a small part of your body (like your forearm) to ensure that you donโt react to any of the essential oils before committing to your whole body.
Some of the essential oils included can cause skin irritation, but the dosing is low enough that Iโve never had anyone react to it.
One thing that makes this homemade mosquito repellent different from DEET is the frequency of application. You may find that it wears off in an hour or two, so keep the bottle handy for reapplication if youโre outdoors for extended periods of time.
How to store
Store the bottle in a cool, dark location for 6 months. I make a fresh bottle every spring when the mosquitos start hatching and then refill as needed until the season is over.
FAQ About Homemade Mosquito Repellent
What smell do mosquitos hate the most?
There are many scents that repel mosquitos (see my complete list above), but the most effective ones are citronella, clove, geranium, patchouli, and thyme.
Does this recipe repel ticks, too?
Possibly! The best essential oils for repelling ticks include spearmint, oregano, and thyme essential oil when used in 5% solution. Another study found clove essential oil to have an 83% repellency, and pairing thyme with citronella resulted in a 91% repellency (3% dilutions). Since my recipe above includes clove, citronella (and the optional thyme), it’ll likely help ward off ticks as well.
If you frequently come into contact with ticks, I highly recommend making my Homemade Drawing Salve to have on hand!
Do I have to use all of the essential oils?
No, if you donโt have them all on hand; you can use what you have as long as you stick with 50 drops for a 2% solution. However, using them all together has a synergistic effect in that they are more powerful when used together than if by themselves.
Can I make the solution stronger than 2%?
Sure, you can certainly give it a try if you’d like an extra strong mosquito repellent. Just make sure to add extra drops of Polysorbate-20 (1 drop per 1 drop of essential oils) so that the solution is properly emulsified. However, if you notice any skin irritation, please back down to the 2% solution.
What’s the best way to soothe mosquito bites?
The hands-down best way to get immediate relief is my Soothing Chickweed Salve Recipe. It works WONDERS on mosquito bites, stings from nettle, painful scrapes, you name it. If you’re someone who reacts strongly to bites and stings, definitely check it out!
Is this safe for children?
Yes, this is safe for children over the age of 2, but consider diluting it to a 1% solution (25 drops essential oils + 25 drops Polysorbate-20 in 4 oz). Do not use on children younger than 2 years old.
Is a small amount of DEET safe?
The less DEET you apply, the better. According to Health Canada, a product containing 30% (or less) DEET is recommended for adults and children older than 12 years old. Children should use 10% or less. Stay away from the mega-doses!

Hi,
This is super helpful, thanks! I just wanted to know if we could plug it into vaporiser? Does it work that way?
Thank you so very much for this article and mostly the recipe I super appreciate youโฆโฆ.Do you have a recipe for flies?? Flies are all over my porch and come in my house. They are very bad. Thank you
Hi there and you’re welcome! No, I don’t have a fly recipe yet. Sorry!
Hello there!
Research palmarosa (Cymbopogon martinii) in regard to its efficacy compared to DEET. Rather excellent results! I make a spray for my dogs (and us!) using neem oil, palmarosa, lavender, and lemon eucalyptus (only small amount of this).
Thank you for sharing this with us ๐
Kath
Ooo thank you so much for this suggestion! I’ll look into it for sure.
Is there a substitute for the Polysorbate 20? I have concerns about the dioxane component
Great question! Another alternative would be Solubol (4 drops for each drop of essential oil).
Is it safe for use around pets? I have read that essential oils are toxic to dogs and cats.
Great question! I know many essential oils are toxic for cats, so I’d avoid using it on your cats. Dogs are less sensitive to them, but I would avoid clove, peppermint, and pine (source: https://www.petmd.com/dog/general-health/are-essential-oils-safe-for-dogs).
