What Causes an Increase in Mosquitoes?

Hundreds of species of mosquitoes live throughout the world. These mosquitoes have adapted to the human environment and spread diseases. Their reproduction cycle is accelerated by favorable settings. They require standing water to complete their life cycle. They lay eggs directly on the surface of water, which then hatch when water covers them.

Mosquitoes carry diseases like malaria, dengue, chikungunya, and Zika. These diseases kill more than a million people each year. They are endemic in Southeast Asia, but are spreading in different parts of the world.

The CDC recommends people to avoid mosquito bites, which can be prevented with the use of insect repellents. Insecticide spraying is used to control populations of mosquitoes, and homeowners should consider installing window screens and door screens.

There are many factors that influence mosquito populations. Climate change is a major contributor to the increase of mosquitoes. Increased rainfall, urbanization, and declines in DDT concentrations all contribute to the increase of mosquito populations.

As climate change continues to affect the world, insects like mosquitoes are expected to move northward and expand their ranges. They will also be exposed to increasing levels of carbon dioxide. This increase is also expected to increase the risk of mosquito-borne diseases.

Aedes aegypti and the Asian tiger mosquito are two of the most common mosquito species. These insects live in tropical and subtropical regions. They are responsible for spreading diseases like malaria, dengue, chikungunya, zika, and yellow fever. Their range extends from the southern United States to southern Australia and Eastern Asia.
