11 Best Outdoor Plants That Repel Mosquitoes

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.

Care Tips for Outdoor Plants That Help Keep Mosquitoes Away

Every plant has its own needs, so it is important to learn about the various plants that you are cultivating to help them to continue growing successfully. 

Learn about soil, sunlight, watering and other needs for the plants to grow. 

Soil for Outdoor Plants That Repel Mosquitoes

Add organic matter to the soil in your yard to increase nutrients in the soil bed.

Water for Outdoor Plants That Repel Mosquitoes

Moderation is the rule in watering. Too much water will drown plant roots, too little water will cause the plant to dry up and die. Remember some plants require consistent moisture. Avoid watering foliage, opting for watering at the soil level.

Light for Outdoor Plants That Repel Mosquitoes

It’s important to know the amount of light your plant needs. Some will like direct sunlight all day, while others thrive in partial shade. This is especially important for outdoor plants.

Pets in the Backyard

Discourage your pets from playing in your garden, especially if you cultivate poisonous plants. They may eat and ingest poisonous plant leaves, meaning a trip to the veterinarian.

Pets might also destroy a well-maintained garden with digging and romping, so it’s best to try and keep them away from plants. 

More Tips for Repelling Mosquitoes Naturally

Crush and Chop

Many plants can be chopped up or crushed, both leaves and stems, to release natural mosquito repellent. Several can be applied directly to the surface of the skin.

Outdoor Plant Location

Position your mosquito repellent plants in the location where you need protection from mosquitoes the most. If you want to sit outdoors, fill the area with mosquito repellent plants. Create a border with the plants around the area. 

Be Aware of the Season

Mosquitoes are most active from March through November, so choose plants that thrive during these months.

Herb Gardens

If you’re passionate about cooking, you may want to integrate herbs into your outdoor garden. Herbs that are particularly efficacious in keeping mosquitoes at bay include:

  • Basil
  • Lemon Thyme
  • Mint
  • Rosemary
  • Sage
  • And then there’s garlic.

So, if you’re a cook, your garden can serve a double purpose by keeping mosquitoes at a distance, while adding fresh and delicate savory hints to dishes and salads.

Other Alternatives to Prevent and Repel Mosquitoes

Environmental Care

Remove any standing water in your yard including ponds, fountains, or similar.

Mosquito Repellent Products

Products that you can purchase to help in the prevention of mosquitoes include citronella candles and specific DEET insect sprays.
