Do you like to spend time outside in your backyard or garden, or on a deck or patio? But when sundown rolls around, out come the bugs.

One bug, in particular, can ruin any outdoor activity, and that is the mosquito, a perennial pain in the backside. Mosquitoes will ruin an evening meal or barbeque, and make you, family, and friends miserable and irritated. 

This article will cover some of the best outdoor plants that repel mosquitoes to help give you insect repellant options that don’t require harmful chemicals.

Perhaps you’ve had your lawn treated, you’ve sprayed arms, legs, and ankles, and still, those nasty critters come out of hiding, having managed to avoid even the strongest repellents.

So, where have they been hiding? Moist garden beds are certainly a possibility.

Can Outdoor Plants Attract Mosquitoes?

Yes, outdoor plants can definitely attract mosquitoes. Only female mosquitoes will bite humans and animals for blood to feed on and for eggs.

Male mosquitoes like to eat certain plant nectar such as water lilies, papyrus, water hyacinths, or taro. If you have a backyard pond or fountain, especially with standing water, you have unwillingly created a breeding ground for these irritating pests.

Backyard garden plants can help repel mosquitoes. They can mask the human scent that attracts females, confuse them, and in some cases, repel them thanks to a strong fragrance.
