Why We Broke Up with Conventional Bug Sprays

Anyone in the crunchy community could tell you that just because something is sold in a drugstore doesn’t mean it’s safe—especially for sensitive skin.

Most bug sprays on the market today are filled with chemicals like DEET that were developed decades ago for military use. And the worst part? Many of them haven’t been tested for long-term effects on developing bodies.

Wait… What is DEET?

DEET (short for N,N-Diethyl-meta-toluamide) is a synthetic chemical developed by the U.S. Army in the 1940s to keep soldiers safe from mosquito bites in jungle warfare. It’s still one of the most common active ingredients in conventional bug sprays because it’s effective at repelling insects, but it comes with a lot of baggage.

Some studies have linked high or prolonged exposure to DEET with skin irritation, neurological effects, and hormone disruption. Add in synthetic fragrances, alcohols that dry out your skin, and other mystery preservatives? It’s no wonder so many people are looking for gentler, natural insect repellents. 

Whether you have skin sensitivities or just prefer to be intentional with what you put on your body, there are better options out there. You don’t have to settle for what’s on store shelves.

Natural Bug Spray Ingredients That Actually Work

Every ingredient in our homemade bug spray recipe is there for a reason—they work! On top of being the best-smelling person at this year’s Fourth of July picnic, the bugs won’t even think about coming near you. Here’s a closer look at why each ingredient works. 

• Citronella: This is the queen of natural insect repellents. It’s been shown to repel mosquitoes and other biting bugs almost as effectively as DEET, but without any of the toxic side effects.
• Cedarwood: Has a rich, grounding scent and is known to repel moths, ticks, and mosquitoes. It’s also soothing for the skin!
• Lemongrass: This bright and citrusy essential oil is both uplifting and helpful at repelling mosquitoes and flies.
• Almond oil: Works as a carrier oil to dilute the essential oils and help them stick to your skin while nourishing your skin at the same time.
• Distilled water: Keeps the formula lightweight, non-greasy, and safe for sensitive skin.

More Bug Bite Prevention Tips (The Crunchy Way)

You can spritz on all the natural bug spray you want, but layering in a few extra prevention tricks can make a big difference. Here are some of our favorite ways to stay one step ahead of those pesky insects. 

• Cover up: Lightweight, long-sleeved clothes and pants help keep bugs away without overheating you. Mosquitoes love black, so choose light colors if possible.
• Time it right: Avoid going outside at dawn or dusk when mosquitoes are most active.
• Add airflow: Bugs hate wind! Use a fan on your patio or sit near a breezy window.
• Avoid fruity scents: Bugs love sweet-smelling perfumes and lotions. Stick to unscented or essential oil-based products.
• Use natural bug-repelling plants: Citronella, basil, mint, and lavender around your porch or patio help deter unwanted, itch-inducing visitors.
• Nourish your skin barrier: Healthy skin is less reactive to bites. Keep your skin happy with goat milk soap, gentle lotions, and plenty of hydration.

Your Homemade Bug Spray Questions, Answered

What Natural Ingredients Help Repel Bugs?

Essential oils like citronella, lemongrass, cedarwood, tea tree, peppermint, and eucalyptus are all known to repel bugs. These plant-based ingredients confuse and overwhelm a bug’s sense of smell, making them less likely to land on you.

Is Homemade Bug Spray Safe for Babies?

Generally, yes—especially when you use baby-safe oils like citronella and cedarwood in proper dilutions. Always patch test first and avoid spraying directly on the face or hands. Instead, spritz clothing or apply to your legs and arms.

How Long Does DIY Bug Spray Last?

We recommend using your homemade bug spray within 1-2 months, especially if you’re not adding a preservative. Shake well before each use and reapply every 1-2 hours when outside, especially if sweating or swimming.

What is the Best Homemade Spray for Bugs?

This recipe with citronella, cedarwood, and lemongrass is our top pick. It’s balanced, gentle, and truly works. You can tweak the essential oil blend based on what you have, what you like, or what bugs are common in your area.

Is Vinegar and Water a Good Bug Repellent?

Vinegar can help repel some bugs with its strong scent, but it’s not nearly as effective as essential oil-based formulas. Plus, vinegar is acidic and can disrupt your skin’s natural pH, leading to dryness or irritation, especially for those with sensitive skin. It’s better suited for cleaning or surface sprays than for direct use on your body.
