The best way to get rid of gnats is by preventing their establishment in your garden or home. Even the best of pesticides are not as effective as prevention, and one very effective way of avoiding gnats is by using certain houseplants. Below are the top gnat deterrent plants to grow:
1. Citronella Plant
- The Citronella Plant is an easy care, tropical foliage plant!

Citronella is a perennial grass that can reach as far as six feet high. You can plant it in a large pot or a planter.
The Citronella plant does well in warm climates and cannot survive the winter. For this reason, you’ll need to plant it in a planter with a caster to enable you to easily carry it in when the frost starts.
You can purchase Citronella balm seeds packaged in a paper seed envelope to put in a seedbed and get your citronella plant. The seeds come with germination and growing instructions displayed on each package to ensure you’re successful in growing them.
Alternatively, you can purchase seedlings and transfer them to your home.
Citronella repels all kinds of pests and especially mosquitos. Its strong smell is what makes these bugs quickly exit your home or garden. You’ll be surprised to learn that several mosquito repellents are manufactured using this plant.

Catnip is another natural repellent suitable for getting rid of gnats and keeping rabbits and deer away from your garden.

The catnip plant is not hard to grow as it can survive extreme weather.
On windy days, the plant’s effectiveness gets hampered. The wind may direct the odor elsewhere, hence reducing the plant’s efficacy.
