The mosquitofish (Gambusia affinis) is the most efficient natural predator of mosquitoes.
The Mosquitofish: A Tiny Predator with a Big Impact
While mosquitoes themselves are responsible for millions of deaths annually through the transmission of diseases like malaria, dengue fever, and Zika virus, the question asks about who kills the most mosquitoes. In terms of natural predators, the mosquitofish stands out.

High Efficiency: Multiple sources cite the mosquitofish (Gambusia affinis) as exceptionally effective at controlling mosquito populations. Its diet consists largely of mosquito larvae, significantly reducing the number of adult mosquitoes that can emerge and spread disease.

Larvicidal Role: The mosquitofish primarily targets mosquito larvae, which are the immature stage of the mosquito lifecycle. By consuming these larvae, it prevents them from developing into disease-carrying adults. [Source: Orkin website on Mosquito Predators]

Ecological Significance: The mosquitofish's impact is not only limited to direct predation. Its presence in an ecosystem can contribute to a broader reduction in mosquito populations, benefiting public health. [Source: West Baton Rouge Parish, LA website on Natural Mosquito Predators]
While other animals, such as certain types of fish (goldfish, guppies, bass, bluegill, and catfish), also prey on mosquito larvae, the mosquitofish is specifically highlighted for its superior efficiency. [Source: Orkin website on Mosquito Predators]
Human Intervention: A Significant Factor
It's important to note that human interventions, such as insecticides and mosquito netting, also play a major role in mosquito control and drastically reduce mosquito populations. However, the question focuses on who is the most efficient natural predator.
