Best Methods to get rid of mosquitoes

Why do You Want to Get Rid of Mosquitoes?

Imagine a gathering with friends and family set outdoors amidst the beautiful scenery. Decorations are up and the mood is energized, until mosquitoes make their rounds. Mosquitoes are small in size, but big in nuisances. They bite a human victim, causing an itchy welt on the skin. Mosquitoes come out in swarms and quickly put an end to any fun since they bite concurrently on any area of the body. Enjoying yourself is not easy when being attacked by swarms of biting mosquitoes. They also carry diseases that can cause illness and even death if left untreated.

Why do Mosquitoes Bite Humans? Do They Only Bite Humans?

Only female mosquitoes bite people. They need the blood to fertilize their own eggs during their reproductive season. Male mosquitoes feed on nectar from plants but females need the lipids found in blood to reproduce. They’ll also bite animals, although the mosquito species determines its preferred animal. Mosquitoes can feed from birds, reptiles or even insects, among others.

It might seem that the majority of mosquitoes in India prefer feasting on a human host whenever possible although only 6% of the over 3000 species feed from human blood. About 100 species can be disease vectors. Even though might seem in the end a low number compared to the total number of mosquito species, they can cause a devastating impact.

Why do mosquitoes bite humans?

Mosquitoes can detect the CO2 (carbon dioxide) their hosts emit with their antennas. The pest also prefers certain smells, just as sweat. Our body emanates via our sweat some organic volatile molecules such as lactic acid, acetone or ammonia. Contrarily, there are also some volatile odorants that either repel or make it difficult for the mosquitoes to find us, e.g. Octonal, Nonenal or Sulcatone (6-methyl-5-hepten-2-one). A study published in the Journal of Entomology concluded mosquitoes are especially attracted to people with Type O blood type.  

How long does it take a mosquito to bite?

Mosquito timings can be very surprising to many people.

  • The introduction of the proboscis (penetrate our skin to find a blood vessel) takes about 50 seconds.
  • Sucking of the blood: 2.5 minutes (a mosquito drinks about 2.8 mg of blood)
  • Proboscis withdrawal: about 5 seconds.
  • The typical itchy sensation can take more than 3 min to manifest after the mosquito finished feeding.

In the video below you can see how a mosquito penetrates the skin with the needle-like proboscis and sucks the blood from a blood vessel.

Do Mosquitoes Transfer Disease?

Mosquitoes are a nuisance to us all but they also cause concern for our health and well-being. Most people worry that mosquito bites will cause them to develop a disease. Is this possible or is it nothing more of a far-fetched worry?

Mosquitoes carrying many different diseases that can be passed to a human who is bitten by the pest. Not all mosquitoes carry or transfer disease, although many do.

Diseases are transmitted by the AedesCulex, and Anopheles mosquitoes globally. Extracted from the WHO official web page. 

Among the diseases that mosquitoes spread include:

  • Dengue: Headaches, fever, joint pain and muscle pain, and rash are among the most common symptoms of Dengue. More than 100,000 people in India are infected with Dengue every year. Transmitted by the Aedes mosquito (mostly by Aedes aegypti). There are four distinct serotypes of the virus that cause dengue (DENV-1, DENV-2, DENV-3 and DENV-4), very closely related. This means that you can be ifected 4 times. There is no specific treatment for Dengue although access to proper medical care lowers the fatalilty rates to below 1%.
  • Malaria: This deadly disease affects millions of people worldwide every year. Symptoms include nausea, fever, and chills, and flu-like symptoms that usually appear within two weeks after infection. Transmitted by the Anopheles mosquito. According to the WHO there were about 386000 deaths for Malaria in 2018. Most Malaria cases (93%) occurring in African countries, and India representing 3%, according to the WHO Malaria report 2019.
  • Estimated country share of total malaria cases, 2018 Source: WHO malaria report 2019.

    • Chikungunya (virus): This disease has many of the same symptoms as Dengue. It is not as deadly, but nonetheless of serious concern throughout the country.  The symptoms are debilitating and may persist for several weeks. There is no vaccine and primary treatment is limited to pain medication. It is transmitted by Aedes aegypti and Aedes albopictus mosquitoes.
    • Zika (virus): It is a virus related to West Nile and Yellow Fever, among others. It is usually transmitted through the bit of an infected Aedes agypti or Aedes albopictus mosquito. The illness is usually quite mild, with fever, rash, conjunctivitis and joint pain lasting a few days to several weeks or months. However, cases of microcephaly, a congenital defect of cranium and brain size resulting in profound neurological defects in newborns usually resulting in death have been been positively identified as being caused by Zika infection.  
    • Filariasis (Lymphatic Filiariasis): This disease affects the lymph nodes and is transmitted via mosquitoes. Most cases do not have any symptoms and it goes away on its own. Long-term damage rarely occurs. transmitted by different types of mosquitoes including Culex, Aedes and Anopheles mosquitoes. 99% of infections in India happen when the mosquito Culex spreads the worm Wuchereria bancrofti through a mosquito bite.
    • Elephantiasis: It can be developed by some people as a consequence of the Filariasis desease. It is a syndrome which is marked by severe swelling of arms, legs genitals or breasts.
    • Japanese encephalitis (virus): a kind of infection in the brain caused by being bit by a mosquito bearing Japanese encephalitis virus.

    This list includes some of the most common diseases carried by mosquitoes in India but is incomplete and the pest may carry other diseases not listed here.

    This information leaves many people wondering if AIDS can be transferred from a mosquito to a human. You’ll be relieved to learn that this is not possible. Thankfully, mosquitoes lack the receptors needed to infect cells. Although the many other diseases and viruses, such as those outlined above, are a serious threat, HIV/AIDS is not among them.

    When do Mosquitoes Bite?

    The mosquito species determines the most common time they bite but it’s true that you are more likely to get bitten during certain times of the day and night. Some species prefer their blood meal early in the mornings while others prefer it during the dark hours of the night. Between dusk and dawn is the most common time you’ll experience a mosquito bite.

    Aedes aegypti (which may transmit yellow fever or dengue fever) are day active (diurnal), and others like the Anopheles species (Malaria mosquito) are night active (nocturnal).

    May - October, or the wet monsoon season, is the most common time of the year you’ll experience mosquito bites. Keep in mind that you may experience mosquitoes at any time of the year, depending on your location in the country.

    India receives 75% of its rainfall during the southwest monsoon period from June to September. Indian monsoon rainfall provides ample breeding habitats for mosquitoes, thus leading to more cases of vector-borne diseases. It is not a coincidence that the searches for the terms "rainy season" and "mosquito" the follow the same seasonal pattern and the number of searches are paired in Google trends, for India (image below).

    Where Do Mosquitoes Live?

    Mosquitoes live in weeds, grass, tall brush, and other grassy locations near homes and buildings. They’re attracted to homes with even the smallest amount of standing water on the outside. They begin breeding as soon as they emerge and a female can lay as many as 100 eggs. A little as one tablespoon of water can attract a mosquito from more than 110 km away. They breed during the warm, humid months of the year, laying their eggs either on top of water or in nearby deposits in locations that water collection can occur. Eggs hatch within 72-hours after being moisturized with the water. An egg outside of water can survive for many years.

    Mosquito Life Cycle

    3. After the mosquito is full and satiated it takes it about 5 seconds to withdrawal the proboscis. 

    4. Once it is done with the job and you start feeling itchy the mosquito can already be far away as it takes few min to start feeling the itchiness.

    Mosquitoes have four distinct life stages. Egg, larva, pupa, and adult. An egg is attached together to form a ‘raft’ that floats on water. Up to 200 eggs can stick to this raft at once. Larvae form within 72-hours of the eggs being laid. They live in water but emerge to the top to breathe. The Pupa responds to light changes and other stimuli but still do not move. This is time that the mosquito is transitioning into an adult that can fly. It takes about 2 days for this process to occur during warm weather conditions. Adults remain on top of the water for about 2 days as their wings form.
