11 Insect Repelling Plants Known To Keep The Bugs Away!

Insect Repelling Plants

After a chilly winter and a soggy spring, the warmer weather is like a sweet reward we’ve all been waiting for. I mean, just strolling outside without bundling up in hats and jackets? Pure bliss! But here’s the catch: along with the sun and fun, those pesky bugs, especially those bloodsucking mosquitos, and stinging insects make their grand comeback. Ugh, ain’t nobody got time for that. Many of us, including me, will do everything possible to keep those annoying insects away and enjoy the sun without any disturbances.

Some bug sprays are on the market that work like magic to kill these pests, but don’t they have a role in our Ontario environment? Wouldn’t it be better if you could repel bugs naturally and in a way that supports nature? For some extra armor against the next years coming bug invasion, you can go all out by planting some of these 11 insect repelling plants in your yard.

They’re like your green bodyguards against the mosquito menace!

What Are Pest-Repelling Plants?

These popular herbs and plants possess certain compounds, scents, or characteristics that insects find unpleasant or offensive, causing them to avoid the sunny areas where these plants are grown. We haven’t found any plants for in-laws just yet, but we will keep you posted!

Here are some common characteristics of insect repelling plants for your home or garden:

  • Natural Chemical Compounds: Many insect repelling plants produce natural chemicals, active ingredients, or essential oils that insects dislike.
  • Strong Scents: Insect repelling plants often have strong and distinct scents that mask the attractants that draw insects to your space. These scents can be pleasant to humans but repulsive to insects.
  • Toxicity to Insects: Some plants are toxic to beneficial insects when ingested. Insects that feed on these plants may be poisoned or deterred from further feeding.
  • Physical Barriers: Certain plants have thorns, spines, or prickly leaves that create physical barriers, making it difficult for insects to land or access the rosemary plants.
  • Companion Planting: Sometimes, planting specific insect-repelling plants alongside vulnerable or desirable plants can deter asparagus beetles, cabbage moths, cabbage loopers, and cabbage worms from attacking them.

The Top 11 Best Insect Repelling Plants

  1. Lavender

Lavender is a plant that smells nice and can keep mosquitos away. Some research in 2019 found that lavender plants and lavender oils can make mosquitos stay away for up to six to eight hours. Planting lavender near your house can also bring bees and butterflies because they like purple flowers.

To grow lavender, you should put the plants about 18-24 inches away from each other and make sure they get lots of sunlight. Water them once or twice a week, depending on how dry the soil is and how old the plants are.

Basil (Ocimum basilicum) is a popular culinary herb with a strong aroma that mosquitoes find unpleasant. Placing potted basil plants on your outdoor dining table, flower beds, or windowsills can help keep mosquitoes at bay.

This tough plant can help keep mosquitoes away, but only when you crush it. A professor named Dr. Donald Lewis from Iowa State University found that it’s about 62% as good as DEET, an effective mosquito repellent. You can do this by cutting off some stems and rubbing them between your hands. You can also burn a few twigs on a campfire to keep mosquitoes away.
