You can add color and beauty around your patio, porch, gazebo or any other outdoor relaxation spot by planting these common ornamental plants in your flower beds. These plants can help repel mosquitoes around your favorite outdoor living spaces.

  • Ants
  • Silver fish
  • Ticks
  • Fleas

You can use them in flower beds or near your vegetable garden to repel insects that nibble at your fresh veggies.
