Are you tired of flies buzzing around the kitchen or crashing the garden party? Instead of pulling out a chemical and toxic spray, why not craft a 100% natural fly repellent? With just a few everyday ingredients and five very affordable steps, you get a product that respects both your health and the planet.
Sommaire
Why choose a homemade fly repellent?
You might think the “homemade” version is less powerful than industrial formulas, but in fact, essential oils of lemongrass and peppermint, combined with mild vinegar and black soap, create a formidable combo. From a health perspective, you avoid carcinogenic substances and endocrine disruptors often found in commercial aerosols. Cherry on top, you reduce your plastic waste and control your budget.
Essential ingredients
Five ingredients are enough for a concentrated freshness against flies:
- Water from the tap or filtered (250 ml) as the base
- Apple cider vinegar (2 tablespoons) with mild acidity
- Essential oil of lemongrass (10 drops) and peppermint (5 drops)
- Fresh plants: basil or mint (a few well-washed leaves)
- Liquid black soap (1 teaspoon) to better disperse the oil
Each of these elements plays a specific role: water dilutes, vinegar brings a scent unpleasant to flies, essential oils strengthen the olfactory barrier, and soap helps homogenize the mixture.
Step by step: make your repellent in 5 stages
Step 1: Prepare the liquid base
Pour 250 ml of water into a small bowl or glass jar. Add 2 tablespoons of apple cider vinegar, then stir gently with a wooden spoon. This phase takes less than a minute but determines the overall effectiveness of the repellent.
Step 2: Add the essential oils
Measure your drops carefully: 10 of lemongrass on one side, 5 of peppermint on the other. Drop them into the center of the liquid, then watch as the oil floats at first before gradually mixing. Shake the jar firmly to homogenize everything.
Step 3: Infusion of the plants
Place a few basil or mint leaves directly into the preparation, then let it infuse for 15 to 20 minutes. The idea is to allow the volatile oils from the plants to release into the mixture. When the infusion has developed a slight herbal scent, you are ready for the next step.
Step 4: Filtering and storage
Pour the liquid through a coffee filter or cheesecloth to retain the plant parts. Then transfer the filtered infusion into a reusable glass or plastic spray bottle. Label your bottle with the date to track the product’s shelf life.
Step 5: Transfer to spray
Close the bottle and shake one last time before each use. The black soap, discreet but crucial, ensures that the water and essential oil remain well mixed. Your repellent is finally ready to fight fly invasions, on the terrace as well as indoors.
Usage tips and precautions
Always test on a small area before application, especially if you plan to spray on textiles or plants.
- Shake the spray before each use.
- Aim for high-risk areas: door frames, window sills, trash bins.
- Avoid direct contact with eyes and mucous membranes.
- Store away from light and heat (maximum 1 month).
FAQ
What is the shelf life of this repellent?
Up to 4 weeks if kept cool and away from light. Beyond that, the olfactory potency of the essential oils decreases.
Can I replace citronella essential oil with another?
Yes, lavender or rose geranium also work, but their scent is milder. You can compensate for the lack of acidity with an additional spoonful of vinegar.
Is this repellent safe for pets?
When used externally and at a distance, it does not pose a major risk. Do not apply directly on your cat’s or dog’s skin, and ventilate the room after spraying.
How to ensure optimal effect?
Reapply every 3 hours outdoors and every 6 hours in a closed room. For very sunny days, prefer a time late in the afternoon.
