What is the primary purpose of pest control in public health?

The primary purpose of pest control in public health focuses on managing and reducing pest populations that can spread diseases and negatively impact human health. Pests, such as mosquitoes, rodents, and cockroaches, can act as vectors for various diseases, including West Nile virus, hantavirus, and salmonella. Effective pest control measures aim not only to diminish these populations but also to minimize the risk of disease transmission to humans.

While eliminating all pests from the environment seems like an ideal outcome, it is often impractical and can lead to ecological imbalance. Pests play various roles in ecosystems, and their complete eradication can disrupt natural processes. Moreover, improving agricultural productivity is more closely related to agricultural pest management than public health pest control. Similarly, while aesthetics are important in urban planning and landscaping, they are not the primary concern of public health pest control, which prioritizes protecting community health and preventing disease outbreaks. Therefore, the fundamental goal remains the reduction of harmful pest populations to safeguard human health.
