Identifying Dengue Mosquitoes Is Easier Than You Think — Here’s What You Need To Look For

Dengue continues to pose a significant public health threat. Understanding how to prevent the spread of the disease is essential for protecting both individual and community health. A crucial part of prevention is identifying the mosquitoes that transmit the virus. The main offenders, Aedes aegypti and Aedes albopictus, are not only responsible for dengue but also for other diseases such as chikungunya, Zika and yellow fever. By learning to recognise these mosquitoes and adopting proactive measures, you can greatly reduce your risk of infection.

How can you identify dengue mosquitoes?

• Shape and sizeAedes mosquitoes generally have a slender appearance and are small in size compared to other species. Their bodies typically measure between four to seven millimetres and are black in colour.
• Scale patternsAdult Aedes mosquitoes exhibit unique light patterns and dark scales, which can be found on their abdomen and thorax.
• Leg bandsThese dengue-spreading mosquitoes also feature white stripes or bands on their legs. This distinctive white marking against a black body is a key characteristic that aids in their identification.
• Biting habitsAedes mosquitoes are predominantly active during the daytime, with a tendency to bite in the early morning and late afternoon.
• PostureDengue mosquitoes typically hold their bodies low and parallel to the ground. The downward-angled proboscis is a significant indicator for identifying them.

How to protect yourself against dengue mosquitoes?

There are several ways to protect yourself and your loved ones from dengue-spreading mosquitoes. Some preventative measures include:

• Avoid going outside during peak hoursSince Aedes mosquitoes are most active after sunrise and just before sunset, it is advisable to avoid going outside during these times to reduce the risk of bites.
• Wear appropriate clothingWhen outdoors, ensure that you wear loose-fitting clothing that covers your arms and legs. Make sure your socks and shoes do not leave your feet exposed.
• Use repellentsMosquito repellents can be applied to your skin for protection against bites. DEET-based repellents are generally the most effective; always follow the instructions on the product label.
• Protect your home or office from mosquitoesEnsure that your home or office is well protected with mosquito nets. If nets are not available, it is best to close windows and doors, particularly during peak activity hours. Air conditioning can also help keep mosquitoes at bay.
• Maintain cleanlinessMosquitoes typically breed in stagnant water. Keep your living and working spaces clean by removing potential rubbish containers. Ensure that clogged drains and gutters are cleared to prevent water accumulation.
