Dengue fever is a viral illness transmitted by infected mosquitoes, primarily the Aedes aegypti mosquito. Understanding the peak hours of mosquito activity and the times when they are most likely to bite is crucial for effective prevention and protection against dengue. In this article, we will explore the dengue mosquito bite time and provide insights into when you should be particularly vigilant.

Mosquito Behavior and Feeding Patterns

To understand the dengue mosquito bite time, it’s essential to understand the behaviour and feeding patterns of the Aedes aegypti mosquito. These mosquitoes are known as “daytime biters” and are most active during the early morning and late afternoon. Unlike some other mosquito species that primarily feed during the night, Aedes aegypti mosquitoes prefer to bite during daylight hours.

Peak Mosquito Activity

The peak mosquito activity for Aedes aegypti mosquitoes occurs around two main periods: the hours after sunrise and the hours before sunset. These times are generally referred to as the “dengue mosquito bite time” due to the increased activity of these mosquitoes during these periods.

Morning Peak: After Sunrise

In the morning, the dengue mosquito bite time typically starts after sunrise, around dawn, and continues for a few hours afterward. Mosquitoes are most active during this time as they seek out a blood meal to nourish themselves and lay eggs. It is important to note that mosquito activity can vary depending on factors such as weather conditions, temperature, and the presence of potential hosts.

Afternoon/Evening Peak: Before Sunset

The second peak period for mosquito activity occurs in the late afternoon, typically a few hours before sunset. During this time, mosquitoes become active again, looking for another opportunity to feed. It is important to remain cautious during these hours to minimize the risk of mosquito bites.

Preventing Dengue Mosquito Bites

To protect yourself from dengue mosquito bites, it is crucial to implement preventive measures during the peak mosquito activity periods. Here are some important steps to follow:

Use Mosquito Repellents: Apply mosquito repellents to exposed skin and clothing, particularly during the morning and late afternoon hours. Choose repellents containing active ingredients such as DEET, picaridin, or oil of lemon eucalyptus.

Wear Protective Clothing: Cover your skin by wearing long-sleeved shirts, long pants, socks, and closed-toe shoes during peak mosquito activity periods. Light-colored clothing can help deter mosquitoes, as they are attracted to dark colors.

Use Mosquito Nets: If you are resting or sleeping during the peak mosquito activity periods, use mosquito nets to create a physical barrier and prevent mosquito bites.

Secure Doors and Windows: Ensure that doors and windows are properly fitted with screens to keep mosquitoes from entering your living spaces. Repair or replace any damaged screens to maintain their effectiveness.

Remove Breeding Sites: Eliminate any standing water sources in and around your property, as they serve as breeding grounds for mosquitoes. Regularly empty and clean containers that can collect water, such as flower pots, buckets, and birdbaths.

Stay Vigilant: Remain cautious and aware of your surroundings during the peak mosquito activity periods. Avoid areas with high mosquito populations, such as stagnant water or densely vegetated areas.

Seek Medical Attention: If you experience symptoms such as high fever, severe headache, joint and muscle pain, rash, or bleeding after a mosquito bite, seek immediate medical attention. Early diagnosis and proper medical care are crucial for managing dengue fever.


Understanding the dengue mosquito bite time and the peak periods of mosquito activity is essential for effective prevention of dengue fever. By taking appropriate precautions, such as using mosquito repellents, wearing protective clothing, and eliminating breeding sites, you can significantly reduce the risk of mosquito bites. Stay vigilant, follow preventive measures, and prioritize your health and well-being to minimize the impact of dengue fever.
