This lemony herb is not only soothing in tea but also deters mosquitoes and ants. Its refreshing scent masks human scents that bugs use to locate us.

How to grow: Fast-growing and loves partial sun. Grows well in pots — be sure to prune regularly to control spread.

Tip: Crush leaves and rub on your skin as a gentle repellent.


🌱 7. Peppermint – Repels: Mosquitoes, Spiders

Peppermint oil contains menthol, which is toxic to many pests. Spiders, mosquitoes, and even mice avoid areas where peppermint is present.

How to grow: Thrives in cool, moist environments. Use containers to prevent it from spreading too aggressively.

Spray trick: Mix peppermint oil with water and spray around windows, doors, and cracks.


🌿 8. Thyme – Repels: Mosquitoes, Ants, Flies

Thyme is not only a culinary favorite — it’s also packed with thymol, a compound with strong insect-repellent properties.

How to grow: Low-maintenance and perfect for hot, dry areas. Great as a ground cover or in small herb pots.

DIY idea: Burn dried thyme leaves as a natural mosquito-repelling incense.


🌿 9. Catnip (Nepeta) – Repels: Cockroaches, Mosquitoes

Catnip is 10x more effective than DEET at repelling mosquitoes, according to some studies. It also drives away cockroaches — but cats love it!

How to grow: Grows quickly in full sun or partial shade. Use containers if you have cats, to avoid damage from rolling or chewing.

Note: While it’s safe for cats, too much can overstimulate them — so place it wisely.


🏡 How to Use These Plants at Home

  • Plant near doors, windows, and patios to create a protective barrier.

  • Mix and match plants in containers for a portable pest-control garden.

  • Use dried leaves or essential oils indoors for added repellent effect.

  • Keep plants healthy — a strong, fragrant plant will repel more insects.
