Which of the following is an environmentally friendly method of mosquito control?

Biological control using natural predators is an environmentally friendly method of mosquito control because it leverages the natural ecosystem to help manage mosquito populations. This approach typically involves the introduction or encouragement of organisms that prey on mosquitoes, such as fish, amphibians, or certain insects that feed on mosquito larvae or adult mosquitoes. The method is sustainable as it reduces reliance on chemical pesticides, minimizes potential harm to non-target species, and works in harmony with the environment.

Utilizing natural predators not only decreases mosquito populations but also promotes biodiversity and maintains ecological balance. This method can lead to long-term mosquito management without the negative environmental impacts often associated with synthetic pesticides, which can disrupt ecosystems and harm beneficial insects.
