Homemade Bug Spray That Actually Works! Non-Toxic Recipe (2024)

Love being outdoors but hate getting bit by bugs? Here’s a non-toxic, natural homemade alternative to those harmful store-bought bug repellents. The bonus is this DIY version works as well as those containing DEET! Finally, a homemade bug spray that’s effective against mosquitos, biting flies, ticks, and gnats.

This post was originally published in March 2018 but has been updated for relevancy and photos.

The best part about this homemade bug spray recipe is that it’ll take you longer to read this post than to actually mix up a batch!

In late spring and all through the summer, I’m like a giant beacon for mosquitoes and other biting bugs. If I’m outside and there are mosquitoes within a mile radius, I’m getting bitten. Can anyone else relate?

Thankfully, I also happen to have a pretty awesomehomemade bug bite relief recipe. And if you’re new to essential oils, I highly recommend you read this Essential Oils 101 post. And since it’s summer and you’re looking for natural remedies, I also will highly recommend this natural allergy relief since it seems spring and allergies go hand-in-hand.

It seems to be some type of genetic makeup as my husband can be sitting right next to me, at the same campfire, and not get a single bite… two of our five children have also inherited this unfortunate “bug beacon gene”.

After buying multiple kinds of natural bug spray, many of which didn’t seem to help a single bit, I turned to making our own homemade bug spray, if I actually remember to use it, our outdoor time has never been better or more itch-free!

Why Make Homemade Bug Spray?

It’s simple! We want to avoid the harmful chemicals in commercial bug sprays at all costs!

After ditching nearly all the chemicals in our home, I made it my mission to search out a healthy alternative to the dangerous, mainstream bug repellents. I came across an article that detailed why homemade essential oil bug repellents don’t work as well as their chemical-laden counterparts, especially those containing DEET (which, for the record, will melt holes in a two-way radio, please don’t put it on your skin).

It’s not that essential oils are less powerful at repelling those nasty blood-suckers (in fact, they actually work better than most synthetic ingredients) but because EOs are extremely volatile, meaning they dissipate quickly, they must be reapplied more often (usually once every 30-60 minutes).

Once the essential oil evaporates, the scent is gone and their power over mosquitoes is gone as well.

This is the same for all those mosquito-repelling plants that you’ve been filling your yard with. Unless the plant is actually bruised and releases the oils within the leaves, the plant sitting in your yard has no real mosquito-repelling benefits.

But with the fear of Lyme disease, or West Nile Virus(both diseases carried by insects), many will choose to protect themselves from bites over the concern of potentially dangerous chemicals in insect repellent.

DEET(or N,N-diethyl-meta-tolumide) has been shown to harm the brain and nervous system function. Even more so in children as their skin more readily absorbs chemicals in the environment. The chemicals in these sprays have more potent effects on their still-developing nervous systems.

Thankfully new research is being done on the efficacy of essential oils and, not surprisingly, because these are in their natural form(as opposed to synthetic chemicals meant to mimic these natural compounds),so-called “Super Bugs” aren’t immune to their effects. The bonus is, these natural oils don’t have a negative effect on our bodies.

How to Make Homemade Bug Spray Last Longer

As I mentioned, many homemade bug sprays only work for a short period of time. Once the essential oil scent is gone, so are the bug-fighting powers.

The good news is you can extend the life of your bug sprayby adding vanillin! Sounds weird, I know, but it turns out vanillin (a natural compound extracted from vanilla seed pods) has been added to perfumes for years to slow down the evaporation rate, making the scent last longer. It works by reducing the volatility of essential oils and, in some tests, doubled the length of the potency of the oils.

Real vanillin can be cost prohibitive so I was happy to find that vanilla extract works as a suitable second place option as it still contains some vanillin (steer clear of imitation vanilla, not because synthetic vanilla is harmful when used topically, but because ofthe harmful ingredients like caramel coloring, preservatives and corrosive acids that lurk within).

In addition to vanillin,by combiningseveralessential oils together, your results at repelling multiple species of mosquitoes improves. Did you know there are 176 species of mosquitoes in the United States and 3,500 species worldwide?

Studies explain why certain ingredients can have a repelling effect on mosquitos. Certain oils, like catnip oil, are actually ten times more effective at repelling mosquitoes than DEET. And lemon eucalyptus oil is the first plant-based mosquito repellent to be endorsed by the CDC. This progress is huge and very encouraging!

Essential oils that repel mosquitoes:

My favorite is this Nature Shield blend (or KidSafe Shield Me) which combines many of the oils listed above. I pair it with lemon eucalyptus (which isnottwo oils, but one) and some organic vanilla extract. As soon as warm weather hits, I whip up the following recipe to give our family the best shot at avoiding those itchy bites all summer long.

Natural Bug Spray Ingredients

• Lemon Eucalyptus Oil is an essential oil that has a light, sweet lemony citronella-type scent.
• Nature Shield essential oil – a combination of Citronella, Geranium Egyptian, Lemongrass, Eucalyptus Globulus, Lavender, Tea Tree, and Patchouli, Cedarwood Virginian and Catnip. (If you’re making this recipe for kids under 10 years old, use this KidSafe Shield Me. It’s a combination of Citronella, Grapefruit Pink, Geranium Bourbon, Rosalina, and Patchouli.)
• Organic Vanilla Extract – adding this helps prolong the life of your bug spray once it’s applied to your skin or clothing.
• Organic Witch Hazel – acts as an astringent agent that dissipates quickly on the skin leaving the oils to do their job.
• Organic Neem Oil or Fractionated Coconut Oil – used as a carrier oil to dilute the essential oils to a safe percentage for use.

Instructions to Make Homemade Insect Repellent

This recipe couldn’t be easier to make. Once you have your ingredients, you just mix them all together, shake it up and you’re ready to go!

We do recommend using a dark glass amber spray bottle. Essential oils can deteriorate plastic, so we like using the 4 oz. glass bottles. They’re very durable and we haven’t had any issues with them breaking.

Also, be sure to store this recipe in a dark, temperature-stable cupboard. You’ll want to avoid leaving this in places like your car where the temperature will fluctuate as heat and sun exposure degrade the efficiency of the essential oils.

How to Use Homemade Bug Spray

As I mentioned before, the essential oils in homemade bug repellent will dissipate quickly. Even with the vanilla extract, you’re going to want to reapply this bug spray every 2 hours for the duration you’re outside.

Just to reiterate, if you’re using this recipe on little kids, be sure you’re using the KidSafe essential oils blend.

Because everyone’s chemical makeup is different, you’ll need to experiment with how long this particular bug spray recipe works for you. If you’re exercising heavily and/or sweating, you may need to apply it more liberally and more frequently.

If you’re swimming, you’ll want to dry off completely and then reapply.

Bug Spray Tips & Tricks

• When packing this bug spray for a hike, toss it in your bag in a sealed zip-top bag to avoid possible leaks/spills.
• If you won’t be hiking with this spray,these glass spray bottles are recommended. Even if you are hiking, we’ve had no issues with the glass breaking, but we do choose to be more careful for our kiddos…
• This is why we use these plastic spray bottles for our kiddos, just to avoid the possibility of broken glass. We still recommend packing them in a zip-top bag to avoid leaks.
• When spraying the face, we recommend spraying a little onto your hands and rubbing it onto your face to avoid accidental spraying in the eyes.
