Why Does UV Light Attract Mosquitoes?

Despite the popularity of bug zappers, UV light isn’t an effective way to get rid of mosquitoes. Although some zappers emit carbon dioxide and others use external baits, they don’t kill mosquitoes. In fact, the University of Delaware’s research team found that 31 biting insects were killed in 14,000 insects killed by zappers.

While mosquitoes aren’t necessarily attracted to light, they do use light to regulate their behavior. When they are active, they use UV light from the moon and stars to find their way. They also use UV light to communicate with each other. This helps insects to organize and perform mating activities.

Night-biting mosquitoes, like other insects, are primarily active at night. They are photophobic to short-wavelength light during the day. To avoid dehydration from the sun, they stay in cooler environments. They prefer to feed during the day.

While most mosquitoes are nocturnal, some species are diurnal. In fact, some species hunt during the day. They use a variety of light to guide their movement and to detect the presence of their prey.

These mosquitoes are also attracted to carbon dioxide in the breath of mammals. In addition, they have visual sensors and heat sensors. They also secrete chemicals called “pheromones” in different places. These chemicals help insects to recognize each other.

Mosquitoes have also evolved to use light from celestial bodies. For instance, they are attracted to UV rays from the sun and moon. However, they can’t see red or yellow lights.
