What is a common method used for controlling mosquito populations?

Biological control with mosquitofish is a common method for managing mosquito populations because these small fish are natural predators of mosquito larvae. When introduced into water bodies, mosquitofish can effectively reduce the number of mosquitoes by consuming their larvae before they develop into adults. This method is often preferred in integrated pest management strategies because it is environmentally friendly and sustainable, reducing reliance on chemical insecticides which can have harmful side effects on other aquatic organisms and ecosystems.

Additionally, using biological control methods like mosquitofish supports biodiversity and can enhance the ecosystem's health while still effectively managing mosquito populations. It is an example of using natural processes to achieve pest control, aiming to balance pest management with environmental conservation.
