With more people concerned about mosquito-borne illnesses and the harsh chemicals in many store-bought bug sprays, the demand for natural solutions is booming. My Nana, a firm believer in the power of nature, has been ahead of the curve for decades. She’s been using her own homemade mosquito repellent since long before it was trendy. Not only does it effectively keep mosquitoes away, but it also smells amazing and is gentle on the skin.

In this article, we’ll walk through the backstory of Nana’s time-tested recipe, break down the science behind the ingredients, show you how to make it at home, and compare it to commercial repellents. Plus, we’ll share real testimonials from people who swear by it and offer storage and usage tips to help you get the most out of this DIY remedy.

1. The Roots of Nana’s Recipe
Nana’s natural mosquito repellent has been in the family for generations. It was passed down from her grandmother, who lived in a rural area where mosquito bites were practically a daily battle. Over time, the recipe evolved to include ingredients that were easy to find locally and known for their bug-repelling properties. Nana recalls her grandmother blending herbs and oils right from the garden.

The final, perfected formula includes eucalyptus oil, lavender oil, and witch hazel. Each ingredient serves a purpose—eucalyptus oil for its powerful scent that drives mosquitoes away, lavender oil for its calming effect and pleasant fragrance, and witch hazel to carry and dilute the oils, making them safe to apply to the skin.

2. What Makes These Ingredients Work
Eucalyptus oil is one of the most effective natural mosquito repellents out there. Its strong, minty scent overwhelms the mosquito’s sense of smell, confusing it and making it hard to detect humans. Studies have shown it can repel mosquitoes for up to two hours.

Lavender oil is best known for its soothing aroma, but it also repels mosquitoes while calming the skin. Witch hazel acts as the base, helping mix the oils evenly and preventing skin irritation. It even has anti-inflammatory properties, which is a bonus if you’ve already been bitten.

3. How to Make It at Home
Here’s what you’ll need:

• 10 drops eucalyptus oil

• 10 drops lavender oil

• 2 tablespoons witch hazel

• A small spray bottle (preferably dark-colored glass)

Start by pouring the witch hazel into the spray bottle. Then add the essential oils. Secure the lid and shake it well to blend everything together. Before each use, give it a good shake to keep the ingredients evenly mixed.

4. Why Natural Repellents Actually Work
Mosquitoes are drawn to the carbon dioxide and body odors we emit. Essential oils like eucalyptus and lavender help mask these scents, confusing the insects and keeping them away. One compound found in eucalyptus oil, called PMD (p-menthane-3,8-diol), has been scientifically proven to be effective in repelling mosquitoes.

5. DIY vs. Store-Bought Sprays
While commercial repellents often contain DEET or picaridin—both known for their long-lasting protection—they also come with potential side effects, especially with repeated use. These include skin irritation and even toxic effects if overused.

Nana’s natural recipe, on the other hand, is free of synthetic chemicals, gentle enough for children, and safe for sensitive skin. It might need to be reapplied more often, but it gives you peace of mind and a fresh, herbal scent instead of that telltale chemical smell.

6. Benefits of Going Natural
Using plant-based ingredients reduces the risk of allergic reactions or skin rashes. They’re also biodegradable and much safer for the environment. On top of that, essential oils bring extra perks: eucalyptus oil has antiseptic properties, and lavender can help with relaxation and stress relief. So you’re not just protecting yourself from bugs—you’re also treating your skin and senses.

7. Common Mistakes to Avoid
Don’t apply essential oils directly to your skin without diluting them—they can cause irritation. Always mix them with a carrier like witch hazel. Another common mistake is forgetting to shake the bottle before each use; the oils and liquids separate over time. Also, make sure you’re using fresh, high-quality oils. Expired or cheap versions may not work as well.

8. Best Ways to Apply It
Spray the repellent on all exposed skin before going outside. Make sure to hit common mosquito targets like arms, legs, and ankles. Avoid spraying near your eyes or mouth. If you’re applying it to kids, spray it on your hands first and then gently rub it on their skin.

Reapply every 2–3 hours or more often if you’re sweating or in a mosquito-heavy area.

9. Real People, Real Results
Sarah, a mom of two, says this repellent is the only one her kids actually like because it smells good. Plus, she feels better knowing it’s safe for them. Tom, an avid hiker, keeps a bottle in his backpack at all times and says it’s become his go-to for outdoor adventures. He prefers it over chemical sprays that leave a residue or stink up his gear.

10. Clearing Up Myths
Some folks think natural repellents don’t work as well. That’s not entirely true. When used correctly and reapplied as needed, they can be just as effective in most situations. Another myth is that they don’t work in tropical areas—but many users have found success in high-risk zones by simply reapplying more frequently.

11. Storing Your Homemade Spray
To keep your DIY mosquito repellent fresh and potent, store it in a cool, dark place. Use a dark-colored glass bottle to protect the oils from light, which can cause them to degrade. When stored properly, your homemade spray should last for several months.

By following Nana’s trusted recipe, you can create a mosquito repellent that’s safe, effective, and kind to both your skin and the planet. Give it a try—you just might never go back to store-bought again.
