Prevent Mosquitoes With These Practical Plants

2. Allium

These eye-catching balls of dramatic purple, blue, pink, or yellow flowers belong to the same family as garlic and onions. More than 700 varieties exist around the world. Alliums love sunlight and will grow in almost any soil. Plant bulbs in the fall and they’ll multiply naturally without fuss from one spring to the next. Seeds may take up to four years to flower, however. Not only do alliums deter mosquitoes, but they also ward off aphids, cabbage worms, and slugs.
