It is believed that many people have high hopes that they can eliminate mosquitoes by planting mosquito repellent, but is mosquito repellent really useful? Some people say it is useful, some say it is useless, and some say it is good to appreciate it even if it is not used. Let's talk about mosquito repellent today.

What is mosquito repellent?

What on earth is "mosquito repellent"? The mosquito repellent grass sold on the market has thick, fluffy leaves with zigzag edges, which are somewhat similar to watermelon leaves. Sometimes, this "mosquito repellent" will also open a pink 5-petal floret, which looks very cute. Take a closer smell, and sure enough, there is a smell similar to lemon.

In fact, this "mosquito repellent" and our common flower plant geranium are "close relatives", called Pelargoniumgraveolens. The fragrance of geranium is due to its ability to synthesize a variety of volatile aroma substances, including geraniol, citronellal and so on. Compared with geranium, the odor of geranium is less irritating, so it can also be used as a raw material for making essential oil.

Is mosquito repellent useful?

Can Pelargonium play a role in repelling mosquitoes? In terms of the substances it emits, geraniol and citronellal can indeed dispel mosquitoes. Unfortunately, these substances are released in large quantities only when the leaves are bitten by mosquitoes, causing damage to plant tissue, which is actually a way for plants to protect themselves. Under normal circumstances, the amount of aromatic substances that plants spread into the air is far from enough to dispel mosquitoes, let alone protect humans from being bitten.

In addition, if you put too many geraniums in the room for mosquito repellent, the smell will be too strong and uncomfortable. It seems that it is not reliable to rely on "mosquito repellent grass" to drive mosquitoes.
