Keeping bugs away doesn’t always require chemical sprays or harsh repellents. Nature provides powerful plant varieties rich in essential oils and aromatic compounds that naturally deter mosquitoes, flies, ants, roaches, spiders, and other pests. Planting these around your home, balcony, or garden can create a natural, eco-friendly barrier—and many are beautiful or edible as well.

Mosquitoes dislike strong herbal and citrus scents. These plants work best when leaves are crushed or placed near seating areas.

- Basil – Repels mosquitoes and fruit flies; ideal for kitchen windows.
- Peppermint – Strong aroma repels mosquitoes, ants, and spiders.
- Lemon Balm & Lemon Verbena – Pleasant smell and perfect for balconies.
- Camphor Tree (Kapoor Tulsi) – Widely used in India for mosquito control.
- Catnip – Highly effective mosquito deterrent (but attracts cats).

Flies dislike sharp herbal and resinous scents.
