How Mosquitoes Bites

You are cooking your dinner while enjoying the sun in your backyard and you feel the sting of a needle on your arm when you see a mosquito.

Have you ever thought?

What are these annoying bugs?

Why do they bite?

Do they cause diseases and what can you do to protect yourself from them?

In this content, we'll show you 

• what mosquitoes are

• How they find humans    

• How they bite

• what you can do to control them.

 

Introduction to Mosquitoes:

Insects known as mosquitoes have been around for more than 30 million years and it appears that mosquitoes have improved their ability to find humans to bite over the course of these millions of years.

How mosquitoes track the human:

A collection of sensors on mosquitoes allows them to follow their target. There are three types of sensors.

Carbon dioxide and lactic acid can be located by mosquito chemical sensors up to 100 feet away. Humans and birds release these gases into their breath. Some chemicals in sweat also attract mosquitoes.

If you move while wearing clothing, mosquitoes can see you and prey on you with the help of visual sensors.

It's a good bet that anything moving is "alive", and full of blood, so it's a good strategy.

Mosquito heat sensors can detect heat, so they can easily detect warm-blooded humans and birds.

Anatomy of mosquito:

Like all insects, the mosquito's body has three basic parts:

Head - This is where all the sensors with cutting tools are located

The head has two compound eyes, an antenna for sensing chemicals and parts of the mouth called proboscis.

Only female mosquitoes have proboscis

Thorax - This is the part where two wings and six legs join

The compound heart, certain nerve cells, and the flying muscles are all present in it.

Abdomen - This part contains the organs of digestion and excretion.

 

Mechanism of mosquito bite:

When a mosquito bites, it uses its mouthparts to pierce the skin and find a blood vessel. The mouthparts consist of a sharp, needle-like structure called a proboscis, which is made up of several parts including the mandibles and maxillae.

The mosquito uses its mandibles and maxillae to cut through the skin, while at the same time injecting saliva into the wound. The mosquito's saliva contains a variety of substances, including anticoagulants and anesthetics, which help the mosquito feed on blood without being detected and without the blood clotting.
The anticoagulants prevent the blood from clotting, which allows the mosquito to continue to feed without interruption. The anesthetics numb the area around the bite, so the person being bitten is less likely to feel the mosquito and may not notice the bite until later.

After the mosquito has finished feeding, it withdraws its mouthparts and flies away. The bite site may become red, swollen, and itchy, which is a result of the body's immune response to the mosquito's saliva. This immune response can also cause the area around the bite to become inflamed, leading to the characteristic bump that is often associated with mosquito bites.

 

What you can do to prevent from mosquito bite:

There are several measures that you can take to prevent mosquito bites:

Use mosquito nets: Use mosquito nets over beds or around outdoor living areas to prevent mosquitoes from entering.

·       Use insect repellent: Use insect repellent on exposed skin and clothing to prevent mosquitoes from biting you. Look for products that contain DEET, picaridin, or oil of lemon eucalyptus, which are effective repellents.

·        Wear protective clothing: Wear long-sleeved shirts, long pants, and socks to reduce the amount of exposed skin that mosquitoes can bite.

·        Avoid peak mosquito hours: Mosquitoes are most active during dawn and dusk, so try to avoid outdoor activities during these times.

·        Eliminate standing water: Mosquitoes lay their eggs in standing water, so remove any standing water around your home, such as in flower pots, buckets, or birdbaths.

·        Keep doors and windows closed: Use screens on doors and windows to keep mosquitoes from entering your home.

·        Use outdoor fans: Mosquitoes are weak fliers, so using outdoor fans can help to keep them away from you.
By taking these precautions, you can significantly reduce your risk of mosquito bites and the transmission of mosquito-borne diseases.
