Nothing ruins a relaxing evening outdoors faster than a cloud of hungry mosquitoes. While no plant creates an invisible force field that sends every mosquito packing, several affordable favorites release fragrant oils that mosquitoes dislike when the leaves get brushed, crushed, or disturbed. Better yet, many of these plants cost less than a takeout meal and pull double duty by adding color, texture, or fresh herbs to the garden.
The secret lies in realistic expectations. A few well-placed plants will not eliminate mosquitoes from an entire yard, but they can become one useful piece of a larger strategy that includes removing standing water, keeping grass trimmed, and encouraging airflow around patios.
