Why Mosquitos Are More Active in the Dark

Have you ever wondered why mosquitos seem to come out in full force once the sun sets? If you’ve spent a summer evening outdoors, you’ve likely experienced the pesky bites that come with dusk. Understanding the reasons behind this nocturnal activity can help us better protect ourselves from these blood-sucking insects.

The Science Behind Mosquito Behavior

Mosquitos are crepuscular, meaning they are most active during twilight hours—dawn and dusk. Several factors contribute to this behavior:

  1. Temperature and Humidity: Mosquitos thrive in warm and humid conditions. During the day, temperatures can be too hot and dry for them to be active. As the sun sets, the temperature drops and humidity often increases, creating a more favorable environment for mosquitos.
  2. Light Sensitivity: Mosquitos are highly sensitive to light. They use light and dark cues to regulate their activity. Bright sunlight can dehydrate and kill mosquitos, so they avoid the harsh conditions of daytime.
  3. Predation: Daytime brings a higher risk of predation from birds and other insects. By being active in the dark, mosquitos reduce their chances of being eaten.
  4. Carbon Dioxide and Heat: Mosquitos are attracted to carbon dioxide and body heat. During the evening, humans and animals tend to gather outside, emitting more carbon dioxide and heat, which mosquitos use to locate their next meal.

Protecting Yourself from Evening Bites
