You can spend your time outdoors enjoying the natural beauty in the summer season. However, with the summer season comes insects and bugs. They are irritating, and sometimes it can be excruciating.

Most people become prone to mosquitoes because of light, humidity, and heat. However, if you are a mosquito magnet, you probably have itchy and bumpy skin.

The bug bites bring the bug-borne disease-carrying insects, which can threaten your children and your family. Many types of mosquitoes carry the West Nile virus, and some carry the malaria-like virus.

Even some species get attracted to carbon dioxide and some of the odors.

The thought of this can make you feel uneasy and scary. Also, repelling mosquitoes and other bugs with chemical repellants every day can harm your family.

So, you may think of some natural insect repellent, which can come in handy instead of the chemical sprays. Many natural insect repellents have been used for generations and are very effective.

When you use any repellant, the product is working if you can smell them. Moreover, natural bug repellents are the most promising.

Even natural insect repellents are more effective than chemically made sprays.

What Are Natural Insect Repellents

The plant-based insect repellents have been used since ancient times. However, it was used as personal insect repellents.

Our predecessors have gained knowledge about these natural repellents from ethnobotanical studies. It was a valuable resource for the creation of natural products.

Lately, commercial insect repellant contains plant-based repellants and has gained a lot of popularity. Commercial plant-based repellents are very safe to use when compared to synthetic repellants.

However, there is still insufficient knowledge about mosquito repellents, and it needs further standardized studies. There need to be better products that will ensure the complete safety of consumers from these plant-based repellents.

Composition Of Natural Insect Repellents

Plants have a compound to protect themselves from the attack of phytophagous insects. The compounds of the plants have a defense against plant-eating insects. However, they are also effective in repelling mosquitoes and other bugs.

Plants often produce green leaf volatiles when their leaves get damaged. The mosquito repellents have geranyl acetate and Citronella, and some geranyl acetone. Also, it is found that the same odor that responds to DEET also affects thujone eucalyptol and linalool in Culex quinquefasciatus.

DEET has a receptor named has OR83b, and Citronella stimulates this. However, it is also modified by the TRPA1 cation channel.

You may wonder why the plant volatiles is repelling mosquitoes and other bugs. It is because they have high vapor toxicity to insects.

What Can You Use As A Natural Insect Repellent

In earlier days, they hung the plants in houses to sweep the bugs and bite insects. The plants were also used as crude fumigants to use the bug repellent’s property. The repellency property of the plant materials is now being used for hundreds of years. 

However, they were burnt to use the property, and later the oil formulations were applied on the skin or clothes for mosquito protection and to increase repellent efficacy.

Since the only method available to them for preventing mosquito bites are natural repellents. The plant oils are still used in the traditional form but rural areas. However, natural insect repellents are used more in some areas in Europe and North America because they think plant-based repellents are much safer and more efficient.

Even you should use natural bug repellent for mosquito control.

1. PMD Extracted From Lemon Eucalyptus

The lemon eucalyptus is also known as Corymbia Citriodeora or Myrtaceae. It is a natural insect repellent extracted from the lemon eucalyptus leaves.

The oil of lemon eucalyptus is an essential oil with more than 85% citronella oil. Also, this essential oil is used in the cosmetic industry since it has a refreshed smell and has no risk of skin irritation.

It is acknowledged that the leftover water distillate of hydro-distillation from the essential oil is incredibly effective in repelling mosquitoes. This water is more effective than the essential oil itself. The extracted oil of lemon eucalyptus repels mosquitoes for some minutes. The lemon eucalyptus oil effect can even last for multiple hours. The essential oils found in most plants are not as long-lasting and effective as this natural oil.

However, the lemon eucalyptus oil leaves the user unprotected and lasts for a few minutes. But, the para-menthane 3, 8 diols, comparatively has a low vapor pressure and witch hazel, thus giving more protection and lasting for hours since this insect repellent has a broad range of insect repellant protection.

PMD is a natural bug repellent extracted from the lemon eucalyptus plants and confirmed for use in disease-prone areas. The lemon eucalyptus oil has an excellent record in preventing mosquito bites and diseases like malaria and yellow fever. Moreover, this has no serious risk to human health.

However, you should know that this insect repellent does not have Environmental protection agency registration for use as a natural bug repellent. But, it is very much effective for repelling disease-carrying insects.

It is one of the essential oils you can use to keep your family safe from the bugs in summer, and it can be intensely used as a mosquito repellent.

Mix one part of the lemon eucalyptus oil with the other ten parts from sunflower oil to make this repellent. You can even use witch hazel in the mixture. But, it would be best if you were careful in front of kids while using this.

2. Citronella Oil

Essential oils extracted from the citronella genus plants are often used as plant-based mosquito repellants. The Cymbopogan nardus is mainly sold in Europe and North America out of all the natural oils extracted from this tree.

Citronella has been very popular now and has made its way into many pest control companies. However, people use this natural oil in perfumery, and the name for this oil was derived from the French Citronella in 1858.

In the early days, this oil was used as a bug repellent by the Indian Army. Since then, Citronella has been used as a natural bug repellent and is widely used. However, this mosquito repellent is used within 5-10% concentrations, lower than other commercial repellants.

If any repellant has high concentrations, then it can cause skin irritation. Unfortunately, there has not been enough research on essential oils extracted from Citronella’s efficiency. However, the citronella oil can only protect the user from the host-seeking mosquitoes for one to two hours.

Citronella oil contains citronellal, geraniol, citral, alpha-pinene, and limonene, equally effective as DEET. However, the oils evaporate very quickly, which results in a loss of efficiency and also leaves the user unprotected. But, the volatile oil release is delayed by adding the essential oils of Cymbopogon winterianus and 5 percent of vanillin. Through this, the natural bug repellent’s protection time is also increased.

Lately, the release rate of oils has been delayed more with the help of nanotechnology. From this achievement, the protection time of the natural bug repellents is increased with a broad range of mosquito repellent abilities.

Also, the encapsulated citronella oil is made from homogenization with 2.5 percent of surfactant and 100 percent of glycerol. It forms regular droplets, which can prolong the retention of the oil and delay the release even more. If the release of volatile is reduced, the mosquito repellent property will last longer.

There is even another method for increasing the protection time of essential oils extracted from the Citronella. With the help of these technologies, a natural bug repellent will change the repellent market and increase the use of natural bug repellents. The bug repellent’s property will last for 30 days by adding the Gelatin-Arabic gum microcapsules.

However, a citronella-based repellent compound must not be used in disease-prone areas. But, areas that are not developed or do not have natural alternative repellants can use Citronella bug repellent. It can even protect from disease vectors.

3. Neem

The most widely used natural bug repellent is Neem. This natural bug repellent has been tested against arthropods. The results of Neem are compelling in preventing mosquito bites. However, the EPA(Environmental Protection Agency) has not given any approval for the use of Neem as a topical repellent.

Since the Neem results for bug repellent can be due to varying methodologies and the different solvents used. Also, neem oil has low dermal toxicity, which has a high rate of causing skin irritation. It can even cause dermatitis if used when it is undiluted.

Whenever you touch DEET, do not forget to wash your hands. Since this can cause skin problems, wash your child’s skin to clear any evidence of DEET.
