There are countless ways to get rid of mosquitoes — from sprays and mosquito coils to essential oils. However, not everyone feels comfortable using chemical repellents because of their potential effects on health and the environment (Healthline). If you’re looking for a safer, natural approach, here are several effective and science-backed methods to repel mosquitoes from your home.

1. Lemons and Cloves — A Natural Mosquito Repellent

Lemon and clove are a surprisingly powerful combination against mosquitoes. Simply cut a lemon in half crosswise and insert several dried cloves into the exposed surface. The aroma released from the mixture of lemon oil and clove’s eugenol compound acts as a natural repellent that mosquitoes find unbearable (Medical News Today).

The more cloves you use, the stronger the fragrance — and the better the repelling effect. You can buy dried cloves easily at herbal stores, traditional medicine shops, or spice markets. Place the clove-studded lemon in mosquito-prone areas like your kitchen, bathroom, or living room. For convenience, set it on a small plate for easy cleanup.

According to research published in the Journal of Insect Science, natural plant-based repellents such as clove oil can be nearly as effective as DEET when applied correctly, offering a safer alternative for households with children or pets.

2. Reuse Coffee Grounds

If you’re a coffee lover, don’t throw away those used grounds. Once completely dried, coffee grounds can be burned to produce a light smoke that helps repel mosquitoes. The scent masks the carbon dioxide humans exhale — which is what attracts mosquitoes the most (BBC Future).

When burning coffee grounds, remember to keep windows open for ventilation and watch the area carefully since coffee grounds smolder without producing flames. This method works particularly well in corners and near entryways where mosquitoes gather.

3. Use Dried Grapefruit or Pomelo Peel

Pomelo (or grapefruit) peels are rich in natural essential oils such as limonene, which can repel mosquitoes effectively (Mayo Clinic). Dry the peels under sunlight and burn a few pieces when needed. The pleasant citrus aroma not only keeps mosquitoes away but also freshens the air in your home.

Place the burning peel near doorways, windows, or air vents, ensuring there’s proper airflow and no flammable materials nearby.

4. Harness the Power of Essential Oils

Mosquitoes dislike many plant-based scents. Oils like lavender, citronella, lemongrass, peppermint, eucalyptus, and clove have proven mosquito-repelling properties (Healthline, 2023). You can diffuse these oils using an aroma diffuser or mix a few drops with water to mop floors.

Citronella oil, in particular, has been used for decades as a natural repellent. According to Medical News Today, citronella candles and sprays can reduce mosquito bites by up to 50% when used in enclosed or semi-enclosed areas.

5. The Simple Power of Menthol Oil

A household staple in many Asian homes, menthol oil (often found in medicated balms) can also keep mosquitoes away. Apply a few drops to areas where mosquitoes appear frequently, or gently rub a small amount on exposed skin.

You can even add a drop of menthol oil to your fan blades — as the fan runs, the aroma spreads throughout the room, creating an invisible shield against mosquitoes.

Final Thoughts

Natural mosquito repellents are not only affordable but also safer for your health and the planet. While chemical repellents might work faster, using eco-friendly alternatives like lemon and clove, coffee grounds, or essential oils can keep your home fresh and free from mosquitoes without the worry of harmful side effects.
