Dengue fever is a serious viral disease caused by the bite of the aedes aegypti mosquito. What makes this mosquito particularly dangerous is its unusual biting pattern; it strikes during the day rather than at night. As dengue cases rise sharply during the monsoon and post-monsoon seasons, understanding this mosquito’s habits is vital to protect yourself and your loved ones. The aedes aegypti mosquito is small but highly adaptable, thriving in urban areas where clean, stagnant water collects in household items such as buckets, plant trays, flower pots, and discarded containers. Unlike other mosquito species, it prefers human blood, increasing the likelihood of spreading infections in populated neighbourhoods. Besides dengue, this mosquito also transmits chikungunya and zika viruses. Recognising its behaviour, identifying breeding areas, and taking preventive steps such as eliminating standing water and using repellents are key to staying safe from dengue during the day and throughout the season.
How to identify a dengue mosquito : Key features and signs to look for
Recognising the Aedes aegypti mosquito early is crucial for timely prevention and control. Unlike ordinary mosquitoes, this species has distinct physical and behavioural traits that make it easier to identify. The Aedes aegypti mosquito is small, dark in colour, and easily recognisable by the white markings on its legs and a lyre-shaped pattern of white scales on its thorax (upper body). These unique markings give it a striped appearance, earning it the nickname “tiger mosquito.”
They usually fly low to the ground, moving quickly and often targeting the ankles and lower legs. You are most likely to find them indoors or in shaded areas around the home, such as under tables, beds, or behind curtains, where they can rest and wait for human hosts. If you notice small, dark mosquitoes with white stripes flying during the daylight hours, especially in the early morning or late afternoon, it is likely Aedes aegypti. Spotting them early allows you to take immediate action by cleaning up breeding sites, covering water containers, and using repellents to protect your household from dengue.
When and where dengue mosquitoes are most active
The activity of dengue mosquitoes depends largely on the time of day and environmental conditions. Aedes aegypti mosquitoes are most active shortly after sunrise and just before sunset. However, if they are disturbed or hungry, they can bite at any time of the day, even indoors. According to a study published in the journal Parasites & Vectors, Aedes aegypti mosquitoes show two peak biting periods in the early morning and late afternoon, making daytime protection crucial. As dengue cases rise sharply during the monsoon and post-monsoon seasons, understanding this mosquito’s habits is vital to protect yourself and your loved ones.
They prefer dark, cool, and shaded places inside homes, such as behind curtains or under furniture. Urban areas provide them with ideal conditions to breed, as they can easily find clean water stored in containers, clogged drains, and open tanks. Warm and humid weather, especially during the rainy season, helps them multiply rapidly. Therefore, you are more likely to encounter these mosquitoes during and after periods of rainfall when water tends to collect in and around the house.
Why dengue mosquitoes bite during the day
Most people assume that mosquitoes only bite at night, but aedes aegypti are different. These mosquitoes have adapted to human lifestyles and are more active during the day because that is when people are awake and moving about. This increases their chances of finding a human host.
They also prefer to live indoors or in shaded outdoor areas where they can easily rest and feed. These mosquitoes are known to be quick feeders, often biting multiple people in a short span of time. This behaviour makes them extremely effective in spreading the dengue virus from one person to another. Because of their unusual daytime activity, it is important to stay protected not just at night but throughout the day, especially in high-risk seasons.
Preventing dengue mosquito bites and breeding
The best way to prevent dengue is to stop mosquitoes from breeding and to avoid bites. Simple, consistent actions at home can significantly reduce the chances of dengue transmission.
To prevent mosquito bites:
Apply mosquito repellent on exposed skin during the early morning and late afternoon.
Wear long-sleeved shirts and full-length trousers in light colours, as dark colours attract mosquitoes.
Keep fans or air conditioning on, as mosquitoes struggle to fly in strong air currents.
Install fine mesh screens on windows and doors to prevent mosquitoes from entering.
Use mosquito nets while sleeping, especially if you nap during the day.
To prevent mosquito breeding:
By following these steps, you can break the mosquito life cycle and reduce the chances of dengue transmission in your surroundings. Dengue prevention depends largely on awareness and consistent hygiene practices. Aedes aegypti mosquitoes breed in very small amounts of water, so even a neglected flowerpot or bottle cap can become a breeding site. By keeping your surroundings dry, clean, and well-maintained, you can protect your household and community from dengue.
Simple daily habits like checking for standing water, using repellents, and keeping living spaces well-ventilated can go a long way in preventing mosquito bites. Remember that these mosquitoes bite during the day, so protection should be maintained from morning to evening. With alertness and regular preventive action, staying safe from dengue is entirely possible.

To prevent mosquito breeding:
- Empty, scrub, and dry water containers such as buckets, plant trays, and pet bowls every two to three days.
- Cover water storage containers tightly to stop mosquitoes from laying eggs.
- Clean drains, gutters, and rooftop pipes regularly to prevent water accumulation.
- Dispose of old tyres, cans, and bottles that collect rainwater.
- Change the water in flower vases and plant saucers frequently.
