Here’s a simple and effective DIY Natural Bug Repellent Spray that can help repel flies and mosquitoes. While no homemade spray can guarantee eliminating insects in exactly 2 minutes, this recipe can make your space much less attractive to them when used consistently.
DIY Natural Bug Repellent Spray
Ingredients
- 1 cup (240 ml) distilled water
- ½ cup (120 ml) witch hazel or white vinegar
- 1 tablespoon rubbing alcohol or vodka (helps disperse the oils)
- 15 drops citronella essential oil
- 15 drops eucalyptus essential oil (or lemon eucalyptus)
- 10 drops peppermint essential oil
- 10 drops lavender essential oil
- 5 drops tea tree essential oil (optional)
Equipment
- 16-ounce (475 ml) spray bottle (glass or PET plastic)
- Small funnel
- Measuring cups and spoons
Instructions
- Wash and dry the spray bottle.
- Pour in the distilled water.
- Add the witch hazel (or white vinegar).
- Stir in the rubbing alcohol or vodka.
- Add all the essential oils.
- Close the bottle tightly.
- Shake vigorously for 20–30 seconds before every use, since essential oils naturally separate from water.
How to Use
Indoors
- Spray around windows and door frames.
- Mist curtains, screens, and entryways.
- Spray under tables and near trash bins.
- Reapply every 2–4 hours or after cleaning.
Outdoors
- Spray patio furniture.
- Mist around decks and porches.
- Spray around garbage cans and outdoor seating.
- Reapply every 1–2 hours during peak mosquito activity.
Why These Ingredients Work
- Citronella: One of the best-known natural mosquito repellents.
- Eucalyptus: Helps deter mosquitoes and flies with its strong scent.
- Peppermint: Repels many flying insects and leaves a fresh smell.
- Lavender: Can discourage mosquitoes while adding a pleasant fragrance.
- Tea Tree (optional): Adds antimicrobial properties and may help repel some insects.
- Witch hazel: Acts as a gentle carrier that evaporates more slowly than water.
- Alcohol: Helps the essential oils mix more evenly.
Storage
- Store in a cool, dark place.
- Shake well before each use.
- Best used within 2–3 months for maximum fragrance and effectiveness.
Tips for Better Results
- Keep doors and windows screened.
- Empty standing water where mosquitoes breed.
- Clean up food crumbs and spills that attract flies.
- Cover garbage bins tightly.
- Use fans on patios—flying insects have difficulty navigating strong airflow.
Safety Notes
- Avoid spraying directly into your eyes or onto broken skin.
- Test on a small area of fabric before widespread use, as essential oils may stain some materials.
- Keep out of reach of children and pets. Some essential oils can be harmful to cats, birds, and other animals.
- If you plan to use the spray directly on your skin, replace the vinegar with additional witch hazel and perform a patch test first. Some essential oils are not suitable for young children or during pregnancy, so check their safety before use.
This recipe is intended to repel flies and mosquitoes rather than kill them. For heavy infestations, combining repellents with measures like removing breeding sites, sealing entry points, and using physical traps is typically more effective than relying on a spray alone.
