Why Conventional Bug Sprays Can Be a Problem

Most store-bought bug sprays rely on synthetic chemicals to do their job. The most common is DEET (N,N-Diethyl-meta-toluamide), which has been used for decades — but that doesn't mean it's without concerns.

• DEET can cause skin irritation, rashes, and in rare cases neurological effects with heavy or prolonged use — especially in children.
• Synthetic fragrances added to many sprays can trigger allergic reactions and contain undisclosed chemicals under the umbrella term "fragrance."
• Permethrin (used on clothing) is highly toxic to cats and aquatic life, and should be handled with care.
• Propellants and solvents in aerosol sprays can irritate the lungs and airways, particularly for kids and those with asthma.

💡 The bottom line: For occasional outdoor use on healthy adults, conventional sprays are generally considered safe. But for everyday use, kids, pets, or anyone with sensitivities — a cleaner option is worth it.

DIY Natural Bug Repellent Spray

Best for: Everyday outdoor use, kids & families | Makes: 4 oz spray bottle | Prep time: 5 minutes

What You'll Need

• 4 oz amber glass spray bottle
• 3 tablespoons witch hazel or vodka (as a carrier)
• 1 tablespoon fractionated coconut oil or almond oil
• 15 drops citronella essential oil
• 10 drops lemongrass essential oil
• 8 drops lavender essential oil
• 5 drops peppermint essential oil
• 5 drops eucalyptus essential oil (omit for children under 10)
• Distilled water to fill

Instructions

1. Add witch hazel to your spray bottle first.
2. Add the carrier oil — this helps the essential oils disperse and moisturizes skin.
3. Drop in all essential oils and swirl gently to combine.
4. Top off with distilled water and cap tightly.
5. Shake well before each use and spray on exposed skin and clothing. Avoid eyes and mouth.
6. Reapply every 1–2 hours outdoors, especially if sweating.

💡 Pro tip: Store in a cool, dark place and use within 3 months. Glass spray bottles work best — essential oils can degrade plastic over time.

Why These Essential Oils Work

• Citronella — the classic bug-repelling oil, derived from lemongrass. Masks the scents that attract mosquitoes.
• Lemongrass — contains citral and geraniol, both shown to repel mosquitoes and other insects.
• Lavender — repels mosquitoes, moths, and flies while leaving a calming scent on skin.
• Peppermint — strong scent that deters mosquitoes, ants, and spiders.
• Eucalyptus — lemon eucalyptus oil is CDC-recognized as an effective mosquito repellent.
