World Mosquito Day stands as a pivotal reminder of our global fight against mosquito-borne diseases. Every year on August 20, World Mosquito Day is observed to commemorate the discovery of the link between mosquitoes and malaria by Sir Ronald Ross in 1897-a finding that transformed our understanding of disease transmission and prevention.

Despite their small size, mosquitoes have a profound impact on public health, and misunderstandings about them can hinder effective prevention and control efforts. By clarifying these misconceptions, we can better equip ourselves to combat the real challenges posed by these insects and advance our efforts to reduce the burden of mosquito-borne diseases worldwide.

World Mosquito Day 2024 is on 20 August 2024, let's take a closer look at 10 prevalent myths about mosquitoes and set the record straight.

Myth 1: Mosquitoes Are Attracted To Sweat

One prevalent myth is that mosquitoes are primarily attracted to sweat. While it's true that sweat contains lactic acid and other chemicals, these substances are not the primary attractants for mosquitoes. The real culprits are carbon dioxide and body heat. Mosquitoes have specialized sensors that detect carbon dioxide exhaled by humans and animals. Once they locate a potential host, they are also drawn to the heat emitted by the body. So, while sweating might increase your attractiveness slightly, it's not the main reason mosquitoes might come your way.

Myth 2: All Mosquitoes Bite Humans

Not all mosquitoes are interested in biting humans. Out of the over 3,500 species of mosquitoes, only a small fraction are known to feed on human blood. Many mosquito species prefer the blood of other animals, such as birds or reptiles. Only female mosquitoes bite humans, as they require the proteins in the blood to develop their eggs. Male mosquitoes, on the other hand, feed exclusively on nectar and other plant-based substances.

Myth 3: Mosquitoes Are More Active at Night

A common belief is that mosquitoes are predominantly nocturnal and are most active during the night. While it's true that some mosquito species are more active at dusk and dawn, others are daytime feeders. For instance, the Aedes aegypti mosquito, which is a vector for diseases like dengue and Zika virus, is primarily active during the day. Mosquito activity varies depending on the species and environmental conditions, so protection should be considered at any time of day.

Myth 4: Mosquitoes Are Only a Problem in Tropical Areas

Many people think mosquitoes are only a concern in tropical or subtropical regions. While it's true that tropical areas have a higher concentration of mosquito species and mosquito-borne diseases, mosquitoes can be found in temperate and even some cold climates. For example, the Aedes mosquitoes that transmit West Nile virus and Zika virus have been reported in parts of North America and Europe. Mosquitoes can adapt to various climates, and their presence can vary based on seasonal and environmental factors.

Myth 5: Mosquitoes Can Bite Through Clothing

It's a widespread belief that mosquitoes can bite through clothing, but this is not entirely accurate. While mosquitoes are adept at finding exposed skin, they generally do not have the ability to penetrate clothing. They are more likely to bite areas of the body that are exposed or have thin fabric. Wearing long sleeves, pants, and other protective clothing can reduce the chances of being bitten. However, mosquitoes can still reach skin through thin or loosely woven fabrics.

Myth 6: Eating Certain Foods Can Repel Mosquitoes

Another myth is that eating certain foods, such as garlic or bananas, can repel mosquitoes. While these foods might have some effects on your body's natural scent, there is no substantial scientific evidence to support the idea that they can effectively repel mosquitoes. The best way to avoid mosquito bites is through the use of repellents containing DEET, picaridin, or other proven active ingredients, along with environmental controls to reduce mosquito populations.

Myth 7: Mosquitoes Only Bite in Areas with Standing Water

Many people believe that mosquitoes only breed in standing water. While standing water is a common breeding ground for mosquitoes, it is not the only one. Mosquitoes can lay eggs in very small amounts of water, such as in discarded tires, flower pots, or even rain gutters. It's essential to regularly empty and clean any potential water-holding containers around your home to reduce mosquito breeding sites.

Myth 8: Mosquito Bites Are Just an Irritation

While mosquito bites are often seen as merely an irritation, they can pose serious health risks. Mosquitoes are vectors for several dangerous diseases, including malaria, dengue fever, Zika virus, and West Nile virus. The itching and swelling from a mosquito bite are caused by the body's immune response to the mosquito's saliva, which contains anticoagulants to facilitate blood-feeding. In addition to discomfort, bites can sometimes lead to secondary infections if scratched excessively.

Myth 9: Mosquitoes Can Transmit All Types Of Diseases

Not all mosquitoes are capable of transmitting diseases. Only specific species of mosquitoes are vectors for certain diseases. For example, the Anopheles mosquito is known for transmitting malaria, while Aedes mosquitoes are responsible for spreading dengue fever and Zika virus. The transmission of disease also depends on various factors, including the mosquito's infection status and the presence of the pathogen in the local environment.

Myth 10: Mosquitoes Will Go Away With The First Frost

Some believe that mosquitoes die off completely with the arrival of the first frost. While colder temperatures do reduce mosquito activity and can kill off many of the adults, they do not entirely eradicate them. Mosquitoes have adapted to survive in various climates, and some species can enter a dormant state or find sheltered areas to survive through winter. Additionally, mosquito eggs can endure cold temperatures and hatch when conditions become more favorable.

By combining accurate information with practical measures, we can better protect ourselves and others from the potential health risks associated with mosquitoes and continue to combat the diseases they spread.
