Insect Repellent Plants and Flowers

With rainy weather comes stagnant waters and mosquitoes! Those pesky mosquitoes are not only annoying, they also carry diseases that could spread in your household. So it’s a good thing you can surround yourself with plants and flowers that could keep insects away.

Yes, flowers are not only good for your mental health, they can also double as insect repellents! So the next time you order a “Get Well Soon” bouquet from your favourite Online Florist, make sure you choose these insect repellent plants and flowers to keep harmful creatures at bay.

Basil

First off, your herbs are not just good for cooking flavourful dishes, they can also ward off bugs. The strong scent of basil repels bugs, so even without processing basil or crushing the leaves, you can already benefit from its insect-repelling properties.

If you want something more potent, a study in 2009 found that basil’s essential oil is toxic to mosquito larvae. So keep this herb handy to prevent mosquito infestation in your home!

Chrysanthemum

Chrysanthemum’s powerful insect-repelling property is pyrethrum. This ingredient can usually be found in various insecticides and pesticides.

However, pyrethrum can be carcinogenic, so you need to know the risks in case you want to make a homemade pest repellent. It’s best to keep chrysanthemums away from kids and pets as they could be toxic when ingested.

Floss Flower

The beautiful, fluffy, purple floss flower is not as potent as chrysanthemums, though it does emit an aroma that is unpleasant to mosquitoes. But fortunately for us, as well as to other harmless insects, they are lovely and fragrant.

Lavender

Lemongrass

Citronella, the ingredient you often see in insect repellent candles and sprays, is a natural oil found in lemongrass. Lemongrass can grow up to 4 feet tall and they’re very low maintenance, so you can easily plant them in your garden to repel insects. Even better, they’re great for adding fragrance and flavour in various soups, salads and dishes. Fragrant and yummy!

Marigold

Farmers use the roots of marigolds to repel nematodes, which means you can opt to mix in or intersperse marigolds in your garden to help vegetables or other flowers to grow and benefit from their insect-repelling properties.

Like chrysanthemums, it’s the pyrethrum they contain that repels the insects.

Mint

Mint leaves not only deter mosquitoes away, mint essential oils can also treat bug bites. You can even add mint to your beverage to make it more refreshing. Pretty useful, right? So if you ever plan to have a little herb garden in your home, mint is a must have.

If you want to make a homemade mosquito repellent, you can extract mint oil then combine it with apple cider vinegar and vodka. Voila! Mosquito bites will be a thing of the past.
