Prevent Mosquitoes With These Practical Plants

10. Petunias

Petunias have a built-in insect repellent system that goes beyond mosquitoes. These heat-tolerant, sweet-fragranced flowers secrete a sticky material from their stems. Tiny hairs on the leaves and stems work with this material to deter predatory insects that like to feed on them. Name your favorite color and you’ll likely find a petunia bloom to match, from dainty pastels to exotic patterns and colors. Petunias enjoy full sun, but will also thrive in a partially shaded locale.
