Flies and cockroaches are more than just annoying—they can carry germs and diseases. If you’re searching for a natural and effective way to get rid of them without using harsh chemicals, this homemade repellent spray may be the solution.

Made with garlic and vinegar, two powerful and easily accessible ingredients, this spray creates a barrier that keeps insects away in less than an hour.

How to Prepare the Insect Repellent Spray

This method is simple, economical, and environmentally friendly. Follow these steps to make your own natural repellent.

Ingredients

• 1 head of garlic
• 1 glass of white vinegar (about 200 ml)
• 2 glasses of water (about 400 ml)
• 1 clean spray bottle

Step-by-Step Preparation

1. Prepare the Garlic

• Peel 4 to 5 cloves of garlic.
• Lightly crush them with a knife to release their aroma and active properties.

2. Make the Garlic Infusion

• Place the crushed garlic cloves in a pot with the two glasses of water.
• Bring to a boil and let it simmer for 3 minutes.
• Remove from heat, cover, and let it steep for 10 minutes.
• Once cooled, strain the liquid to remove any solids.

3. Mix the Spray

• Pour the filtered garlic infusion into the clean spray bottle.
• Add the glass of white vinegar.
• Shake gently to combine the ingredients.

How to Use

• Spray the liquid in areas where insects are commonly found: kitchens, bathrooms, near doors and windows, under sinks, behind appliances, or furniture.
• Focus on corners, damp areas, and spots with food residues, where cockroaches hide and flies land.
• Reapply once a day for several days or after each cleaning session to maintain its protective effect.

Why Is This Repellent Effective?

• Garlic contains allicin, a compound with antimicrobial properties and a strong odor that insects dislike.
• White vinegar acts as a disinfectant and intensifies the odor, making the environment less attractive to pests.
• Together, these ingredients not only repel but also disorient insects, forcing them to leave the treated area.

Additional Tips

• To boost effectiveness, add a few drops of eucalyptus or mint essential oil, which are also natural insect repellents.
• Avoid spraying directly on food, utensils, or cooking surfaces. Use it around those areas instead.
• Store the mixture in a cool place and shake well before each use.
• For severe infestations, complement this remedy with thorough cleaning and eco-friendly traps.
