Mosquito is a generic term used to designate several insect families belonging to the Diptera order and, in particular, to the Nematocera suborder although, strictly speaking, it refers only to the members of the Culicidae family. In fact, there are 39 genera of mosquitoes and 135 subgenera in total, with more than 3,200 recognised species. Culex mosquitoes are night biters. They are flying insects with thin, dark brown bodies and long legs. The adults are rarely more than 15 mm long. Their larvae and pupae breed in polluted water from small containers to pools or streams.
Mosquitoes go through 4 stages in their life cycle: egg, larva, nymph or pupa and adult. The females lay their eggs (about 300 eggs a time in some species) anywhere where water remains stagnant for at least one week and the larvae are born and grow there, in the water. After a few days they become pupa, which later open and an adult mosquito emerges from inside it. It is only then that the insect leaves the water. Some mosquito species have life cycles that barely last seven days while others can live for up to one month.
Mosquitoes basically cause two major problems. First, their bites, which cause bad irritation. Second, they could be vectors for various diseases. However, only the females cause these problems because only females bite: they need mammal blood to obtain proteins that required for the development of their eggs. Without blood, the eggs could not develop as mosquitoes mainly feed on nectar, tree sap and fruit juices, which usually have low protein contents. The irritating effect of mosquito bites is the result of an allergic reaction triggered in mammals by perforation of the skin by the mosquito proboscis (a stiletto-like organ used to pierce the skin and which enables them to insert two tubes to inject saliva and suck blood). Before sucking our blood, the mosquito secretes a substance that prevents the blood from clotting. This substance is a powerful anticoagulant and is also the cause of the itching. Mosquitoes have always been vectors of infectious diseases: they can transmit diseases because of their habit of biting different individuals one after the other. The Anopheles mosquito is well-known as a vector of human malaria (a major cause of debilitating disease with more than 200 million cases each year around the world).
All mosquitoes need water to complete their life cycle.
Mosquitoes can fly at speeds between 1.6 and 2.4 km/h.
An adult female weights about 2 mg.
Only the females suck blood. They need blood to develop their eggs. However, they also feed on nectar and juices, like the males.
Mosquitoes beat their wings between 300 and 600 times a second.
Mosquitoes can detect the CO2 we exhale from distances between 18 and 30 m.
Female mosquitoes usually take about 50 seconds to pierce mammal skin and insert the tubes and usually spend about 2.5 minutes sucking blood.
There are more than 3,200 species of mosquitoes.
Mosquitoes can live for several weeks or months, depending on environmental conditions.
Most mosquitoes stay within 1.5 km of where they were born, although some species can move more than 30 km away.
When the females bite, they inject saliva under the skin. This saliva contains proteins that may cause allergic reactions.
Mosquitoes can be found on all continents except Antarctica.
Mosquitoes' natural habitat is near water. However, they are very adaptable so they are found in many places, including cities.
City mosquitoes are able to breed all year round in basements, where there is humidity and heat.
Soft light is a magnet for mosquitoes. But they do not like bright sunlight (which is why there are less mosquitoes during the day).
Do not use dark-coloured clothing as it attract mosquito.
Use physical barriers such as mosquito nets in places with a high mosquito risk.
Avoid soft lighting because this attracts mosquitoes.
Use mosquito repellent such as Liquid, mat/gel mat, paper, gel, coil.
On a daily basis, use aerosol to instantly kill mosquitoes that are already present in your home and follow-up by a repellent product such as liquid, mat/gel mat, paper, coil, or gel to continuously repel and protect against other mosquitoes from entering your home.
