Mosquitoes and insects have been a huge problem all around the world whenever the spring and summer seasons arrive. Animals and humans cannot find a resort from mosquitoes when air temperature rises to the higher end of the thermometer. Luckily, there are numerous methods and products which are designed to help us fight these obnoxious creatures, but most of these products contain many different chemicals, which are designed in laboratories using toxic and artificial substances. Although they have a great ability to deter insects, they also can cause harm not only to humans and animals but also to nature. The most common side effect, when using chemical mosquito repellents are different allergies, skin burns and rash. But it can also lead to more serious and dangerous reactions. You can never know, which chemical will be the one your body is not going to like, therefore it is very hard to avoid such reactions. The only solution is using natural insect repellents, which do not cause any side effects and don’t contain any chemicals and toxins. Therefore I will be discussing some of the most popular natural plants that deter mosquitoes like the citronella grass and lemongrass plant, which are great insect repellents and also are great decorative plants for your garden.

Lemon grass plant

Cymbopogon or better known as the lemon grass plant is a genus of plant from the grass family. In nature lemon grass plant is found in tropical and subtropical climates like Asia, Africa and Australia, but it also can be grown and kept all around the world in households. This plant has a specific citrusy aroma similar to citrus fruits or lemons, hence its name – lemon grass. It grows with linear leaves, similar to ordinary grass, only much taller and bulkier as it can grow as long as three meters in height. Because of its beneficial qualities, distinctive flavor and citrusy aroma lemon grass herb is widely used for different purposes, for example in medicine and culinary and in fighting mosquitoes and insects.

Lemon grass plant is widely used in medicine as it has a significant and strong, citrusy smell and is very beneficial with its antibacterial, anti-fungal and antimicrobial qualities. Lemon grass plant helps with medical problems such as keeping cholesterol levels in your body low and heart healthy, preventing various cardiac issues and diseases.

Also, lemon grass is beneficial in treating various types of cancers, without affecting healthy cells of your body as chemotherapy does. Therefore, if this plant can help even cancer patients, then it must contain extremely beneficial components because cancer researchers have been trying to find cures for decades. Also, lemon grass is helpful with various stomach disorders and infections, as it does contain antibacterial substances. However, lemon grass is not only useful for different physical illnesses but also for emotional ones. For example insomnia, disease, which means that person has difficulty sleeping. Because lemon grass has a therapeutic and soothing smell. All together researchers have shown that lemongrass can help many different illnesses and disorders, including, fever, respiratory disorder, different infections, and aches. You may ask, if it is so full of antibiotics and can heal even cancerous cells, then why people still lean towards antibiotics rather than more natural option as lemon grass. Field of lemon grass in medicine has not been researched to such extent that it could be used to its full abilities as an only source. But for now, it is definitely a great component to medicine.

As lemongrass has a very specific aroma, it is used in various different insect repellents. It not only deters insects and mosquitoes but also helps to prevent different illnesses transferred by insects, for example, Lyme disease. Lemongrass can be planted near walkways or in backyards, preventing mosquitoes with its strong aroma. Although this scent is not harmful to humans and animals, for mosquitoes and insects, lemongrass scent is extremely unpleasant and will keep them away. Also, oil can be squeezed out of lemongrass, which is called citronella, and when it is combined with other components, it creates natural insect repellent. Although similar artificial insect repellents already exist, by using plants, such as lemongrass, we can obtain the same product but with a lot more natural structure.

Although lemongrass oil is natural and considered safer and healthier, than chemicals with similar effect, it still has to be used and handled with caution. Lemongrass mosquito repellent can cause an allergic reaction for some people, causing rash, itching and even asthmatic symptoms. Lemongrass oil is strong and concentrated substance, and if applied to the skin in its raw form can cause a harmful reaction. Therefore lemongrass is only a component of products, oil is not used on its own. However, if used cautiously, lemongrass mosquito repellent oil as a component can be extremely beneficial and helpful whether it is in culinary, medicine or in fighting insects.

Citronella grass

Citronella grass is a species of genus lemon grass. There are different types of citronella grass in Latin called Cymbopogon nardus. It is a tropical plant which in nature is found in East Asia and South East Asia. However, it can be grown in other parts of the world manually by humans. It is easy to cultivate any of lemongrass plants, including citronella grass. Therefore can be easily grown in backyards and gardens. Citronella grass has proven its effectiveness and is the most used natural ingredient for mosquito repellents. Two most popular types of citronella grass are citronella geranium and citronella winterianus.

As already mentioned, citronella grass can be grown along pavements and in backyards. It will emit very specific citrusy smell and keep mosquitos and insects away.

However, also oil can be subtracted from citronella grass, and further used in insect repellents. Citronella has a specific ability to masks smells and scents which attract insects, carbon dioxide and acid of humans. And not only it helps humans to fight mosquitos, citronella also can be helpful to animals when treating fleas. Citronella oil is widely used in insect repellent candles. These candles are a must in almost every garden party. They emit the same strong citrusy smell as the plant, but a lot more concentrated, therefore ensuring effectiveness.

Citronella mosquito plant is not only an effective insect repellent, but it also is very beneficial in other spheres too. It is used in medicine as it has an ability to relieve migraines, tension and even works as an anti-depressant. Citronella is also in medicines which reduce fevers and flu. Also, oil abstracted from citronella grass is used in household cleaning supplies. We can see that these natural oils have very wide variety of uses.

The only downfall to this specific kind of citronella mosquito plant is that it cannot withstand frosts and cold weather. But, it can be planted in direct sunlight, therefore for warmer and desert climates, it will be perfect.

Very similar plant to citronella is pelargonium citrosum, which is also known as a mosquito plant. Citrosa is advertised for its benefits and ability to protect against mosquitos, but in reality, it only has a specific aroma, similar to citronella, and it looks very similar. But this plant does not work great as a mosquito plant or mosquito repellent plant.

Geranium plant

The geranium plant is also very popular among gardeners as an insect repelling plant due to its specific smell. It has a very specific lemon like smell, very similar to citronella, mentioned above. But in addition to its specific smell, geranium plants have beautiful bloom, which makes them not only efficient but also beautiful and decorative addition to your garden. This plant repels leafhoppers, the corn earworm and the Small White. Therefore geranium plant is not an anti-mosquito plant if you are concerned about getting rid of specific mosquitoes. But it is perfect if you are wanting to deter insects mentioned above.

Coleus plant

Coleus plant is a flowering plant, popular for being brightly colored. Coleus plant is very sensitive and as most of the plants mentioned in this article, cannot withstand the cold and freezing weather. It is advised to place them outside in the garden for warm seasons and indoors for the winter seasons.

The way how oil is subtracted from the plant is by crushing leaves and squeezing oil out of them. Oil obtained is very fragrant and spicy, with a very specific aroma. If you would taste it, it tastes somewhere in between peppermint, spearmint, and oregano. Unlike other plants that deter mosquitoes, which all have specific lemony scent and taste. This scent is unpleasant to many insects, therefore horsemint is one of the anti-mosquito plants which is used to ensure that your backyard is free of biting insects and you can enjoy your time outside.

It is not hard to grow horsemint plant, it is very fast-growing, and it can withstand shade and does not mind droughts.

Although its native habitat is Australia, nowadays pampas grass has spread all over the world and can be found in most regions of the world.

Pampas grass does not have specific spicy or very lemony smell as other plants that deter mosquitoes do and are mentioned in this article have. In addition, it does not deter mosquitoes and flying pests. It is not highly advertised that pampas grass is fighting insects and that insects do not like this plant, but it should be noted that insects do not enjoy this plant also. Even if it does not frighten off pests, pampas grass will ensure that they are not living in your garden, because pampas grass does not attract insects.
