Plants That Repel Pests

Basil

There are plants that repel pests by emitting odours to deter and confuse insects. Their success in repelling insects will greatly depend on numerous factors like proximity, the breeze, and quantities of plants.

Odours can be released even when you just brush past the plant or water it at a specific time of the day. The effectiveness of the plant’s pest-repelling odour can be enhanced by placing them in areas like pathways, doorways, dog kennels, and near outdoor eating areas.

There are some that can irritate your skin while others, when ingested, are toxic. If you want to use these plants around kids and pets, do comprehensive research first to ensure safety.
