Pennyroyal
Pennyroyal is a lesser-known herb that packs a punch when it comes to repelling mosquitoes. Its strong, minty scent is unpleasant to insects, making it a natural outdoor barrier. However, pennyroyal should be used with caution, it’s toxic if ingested by pets or humans. For that reason, it’s best kept in containers and out of reach of children and animals. It thrives in full to partial sun and grows well in compact spaces. You can place pots near patios or entrances for added protection. Despite its toxicity, when handled responsibly, pennyroyal remains a powerful and effective tool for natural pest control.
