Strong-smelling herbs and flowers have been planted near homes and gardens for centuries because many insects dislike their oils and fragrance. Rosemary, mint, sage, citronella, garlic, lemongrass, and marigolds are among the plants people commonly use to discourage mosquitoes, flies, fleas, and other pests around outdoor spaces.
These plants work best as part of a larger strategy that includes removing standing water, improving airflow, and maintaining clean garden areas. No single plant creates a perfect barrier, but combining several fragrant species can help outdoor areas feel more comfortable during warmer months.
One of the biggest advantages is that these plants serve multiple purposes at once. Herbs provide cooking ingredients, flowers attract pollinators, and aromatic foliage adds beauty and scent to the garden. Functional planting creates spaces that are practical while still feeling vibrant and alive.
