Do Mosquito Repellent Plants Work?

It sound great to have a potted plant around your patio or backyard that not only create attractive greenery but also repel mosquitoes. For outdoor lovers, this would be an excellent solution to these pesky insects. However, do mosquito repellent plants really work?

There are several plants known to have mosquito repelling properties. You have heard of citronella, mints (peppermint, horsemint), Marigolds, lemon balm herb, lavender, petunias, scented geraniums, basil, lemongrass and more. These plants are said to produce fragrances that repel mosquitoes.

Many of mosquito plants contain citronella which is a natural ingredient that has insect-repellent properties. There is no doubt that crushing and rubbing leaves of a citronella plant on skin keeps away mosquitoes. However, the effect is not lasting and cannot be compared to DEET or other citronella scents.

Mosquitoes have incredible sense of smell that help them to locate us by sniffing carbon dioxide we exhale. Mosquito plants are capable of producing fragrances which can confuse a mosquito trying to locate a target. However, plants can only release a significant amount of fragrance when shaken, crushed or burnt.

According to research, there is no evidence that just having citronella plants around will keep mosquitoes away from your patio, garden or home. Substantial amount of research has also establish that there is no significant difference in the number of mosquitoes landing on a person when these plants are present or not.

While rubbing crushed leaves may bring a slight mosquito repelling effect, this can trigger skin allergic reaction for some people. Additionally, essential oils and extracts from citronella plants have a limited life and their effect wears off relatively quickly.

This does not mean that mosquito repellent plants are worthless. Most of these plants provide good ornamental foliage and greenery in a garden. You will also love it when they bloom in summer.
