Are Mosquitoes Attracted to Light? Answered

In the evenings many flying insects will swarm around your porch lights. Bugs rely on light for navigation as they search for food. While most of them may be harmless, female mosquitoes use it as an opportunity to bite you for blood. Let’s find out whether light attracts mosquitoes or not.

Mosquitoes are dreaded insects that attack human being and other animals for blood. The bite of the female anopheles mosquito can transmit a number of serious diseases including malaria. To effectively control mosquitoes in your home and yard, you need to understand what attracts them.

Are Mosquitoes Attracted to Light?

Mosquitoes aren’t really attracted to light the reason you don’t see them during the day. Usually, they become active in the evening or night time. Sometimes they rely on soft natural light of the moon or starts for navigation. The closeness of artificial light from bulbs make it impossible for them to maintain a good angle for clear movement.

Carbon dioxide in breath and sweat is what attracts mosquitoes to their host. This can happen in even total darkness when there is no any visible form of light. It is for this reason most mosquito killers are designed to emit carbon dioxide so that these dangerous insects can be lured into the trap.

What about ultraviolet (UV) light?

Mosquitoes are neither attracted to ultraviolet light. This is the main reason why bug zappers are not effective at killing them. Bug zappers produce ultraviolet light that attracts bugs which are then electrocuted by a highly charged grid. Many studies have established that out of thousands of insects a bug zapper kills per day, less than 5% are mosquitoes.

Most people buy a bug zapper with an aim of exterminating mosquitoes in their homes or backyards but end up with a big disappointment. Mosquitoes remain active even in an areas with a working bug zapper. This led to many questions on how a bug zapper work before it was discovered that mosquitoes are disinterested in UV light.

It is a wrong plan to use a bug zapper on mosquitoes. Thousands of bugs killed by this device are usually harmless. Insects are important part of our ecosystem, they serve as food for many wildlife and act important roles in agriculture such as pollinating and enriching soil with nitrogen.

Does yellow light keep away mosquitoes?

Changing your outdoor bulbs to yellow light is one of the ways of keeping bugs away from porch light. Generally, mosquitoes and other flying insects have smaller visible spectrum compared to humans. It is hard for them to detect a yellow or red light.

Switching to yellow bulbs will incredibly reduce the number of bugs in your outdoor but will not stop mosquitoes from attacking you. Their ability to detect carbon dioxide will still lead them to their host. You should therefore consider other ways of controlling mosquitoes in your yard.
