What are anti mosquito plants?

Anti – mosquito plants are all those that, due to their essential oils and the aroma they emit, keep these insects away, since they tend to avoid them.

Why do they have a repellent effect?

Generally speaking, the essential substances secreted by repellent plantsaffect the sensorsthat allow the dipteran to locate the food source.

Mosquitoes not only use their eyes to search for food, they also rely on their thermal and chemical sensors. For example, their legs can detect the temperature difference between the environment and the victim, while their antennae help them accurately detect the carbon dioxide that we exhale when we breathe.

In this way, the substances of theanti-mosquito plants disorient insects and make them lose their ability to detect. Intoxicated in this atmosphere, the mosquitoes decide to move away to regain their senses.

What are the best-known substances with repellent power?

Among the list of the most effective natural compounds, pyrethrins, methyl-nonyl-ketone, geraniol, estragole, citronellol, limonene and trans-nerolidol have been recognized.

Likewise, there are some compounds that, without being considered as repellents, are well known to have such effects.

Such is the case of coumarin and phytol, two ingredients found in the grass known as Buffalo Grass or Sweet Grass (Hierochloe odorata), a perennial native to Central Europe with a high repellent power but which is very little. used for this purpose.

Basil possesses not just one, but four ofthe volatile mosquito repellents: estragole, citronellol, limonene, and trans-nerolidol, with the former being the most abundant.

In addition, estragole is one of those responsible for its characteristic aroma.


Lavender is an excellent repellent for mosquitoes, moths, fleas, flies, and many other insects. In addition, it has a calming effect and induces sleep.

Buffalo grass (Hierochloe odorata)

As we already mentioned, this herb is an excellent repellent, thanks to its two coumarin and phytol compounds that, in combination, are quite effective in keeping the annoying diptera at bay.

Chrysanthemums repel cockroaches, ants, beetles, ticks, lice, fleas, bedbugs, and mites. The ingredient that makes them so effective is pyrethrin, which is also used as an insecticide because it can easily kill all kinds of flying and jumping insects.
