What method is NOT used for controlling mosquito populations?

Physical control is not a standard method for controlling mosquito populations. Generally, mosquito control methods are categorized into three primary approaches: chemical, biological, and genetic.

Chemical control involves the use of insecticides to kill mosquitoes or disrupt their life cycle. This method is widely used and can be effective in managing outbreaks.

Biological control employs natural predators or competitors of mosquitoes, such as fish that eat larvae or bacteria that infect and kill mosquito larvae. This method leverages the existing ecosystem to reduce mosquito populations sustainably.

Genetic control refers to techniques that involve manipulating the genetic material of mosquitoes to reduce their populations or hinder their ability to reproduce. This innovative approach includes methods such as releasing genetically modified mosquitoes that either produce non-viable offspring or are designed to outcompete wild populations.

While physical methods, such as trapping or habitat modification, may help lessen mosquito presence, they are not categorized formally as a primary control strategy like the other three options.
