Mosquito control is essential for safeguarding public health across Asia, where mosquito-borne diseases like dengue, Zika, and malaria are significant concerns. With Asia experiencing some of the world’s highest rates of dengue fever, the World Health Organization (WHO) estimates that 70% of the global dengue burden is concentrated in the Asia-Pacific region. Tropical and subtropical climates, coupled with rapid urbanisation, create ideal breeding conditions for mosquitoes, highlighting the need for effective, sustainable control measures.

For a robust approach to mosquito management, it’s crucial to combine early detection, prevention, and community education. Here, we explore three essential strategies that help reduce mosquito populations and limit the spread of diseases across Asia.

1. Surveillance: Monitoring and Early Detection of Mosquito Populations

Surveillance is at the core of effective mosquito control, involving ongoing monitoring of mosquito species, population density, and seasonal trends. In countries across Asia, authorities use various surveillance tools, including mosquito traps, gravitraps and drone-based monitoring, to track high-risk areas. This approach allows for early detection of mosquito hotspots and ensures timely intervention to prevent outbreaks.

By continuously monitoring mosquito populations, health authorities gain critical insights into peak breeding seasons and species distribution. Surveillance data guides efficient resource allocation and helps control programs respond to trends in real-time. For instance, early identification of a rise in Aedes mosquito populations can prompt preventive action, reducing the risk of dengue outbreaks in densely populated urban areas.

2. Larval Control: Targeting Mosquitoes at the Source

One of the most effective strategies in reducing mosquito populations is larval control—targeting mosquitoes at their early life stages to prevent them from maturing into adults.Other than chemical options like larvicides, many Asian countries implement biological control agents such as fish predators and mosquito-specific bacteria like Bacillus thuringiensis israelensis, commercially known as Bti.

Larval control tackles mosquitoes at the source by focusing on stagnant water sources, including water storage containers, open drains, and ponds, which are common in tropical urban areas. Community initiatives encourage residents to regularly empty containers and clear areas where water can be collected. For public spaces where stagnant water cannot be eliminated, authorities apply larvicides to prevent breeding. This approach disrupts the mosquito lifecycle and has been proven to reduce overall populations significantly, making it a sustainable choice in high-risk regions.

3. Public Education: Empowering Communities to Participate in Mosquito Control

Public education is key to sustainable mosquito control, as it involves empowering communities to take action. Across Asia, health organisations conduct extensive public education campaigns to inform residents about the dangers of mosquito-borne diseases and simple ways to reduce mosquito breeding sites. In countries like the Philippines, Malaysia, Singapore and Vietnam, public health campaigns emphasise practical steps such as:

• Changing water in flower vases and water storage containers
• Covering water tanks and containers to prevent mosquito access
• Clearing roof gutters and removing stagnant water from plant saucers
• Using insect repellents and mosquito nets to reduce exposure

By educating the public on how to eliminate breeding sites and protect themselves, these campaigns foster community-driven prevention efforts that support wider health initiatives. Empowered with the right knowledge, residents can contribute to creating mosquito-free environments, which is essential for effective and lasting mosquito control.

Mosquito control is about more than just addressing the immediate threat; it’s about building long-term resilience against mosquito-borne diseases. Surveillance helps monitor and anticipate risk areas, larval control interrupts mosquito development, and public education fosters community action. Together, these strategies form a comprehensive approach to mosquito management, supporting healthier, safer communities across Asia.
