Are Mosquitoes Attracted To Light?

Introduction

If you go outdoors after dark, you might see mosquitoes and other flying insects flying around your light sources. Many people assume that this means that mosquitoes are attracted to light. Continue reading to answer the question, “Are mosquitoes attracted to light?”

Mosquitoes And Light

Natural Light

Mosquitoes are most active at sunrise and sunset because they avoid bright light. They need some light to navigate and see where they are going, and they prefer the subdued light available in the early and late parts of the day to help them see.

Artificial Light

When mosquitoes have artificial light available, they use that to help them see. The reality is that mosquitoes aren’t attracted to light. They don’t shy away from it either. They simply use it to see where they are going.

Disorientation

Artificial light is much closer to the mosquitoes than sunlight, and if it’s very bright, it can disorient them. For this reason, you may see them buzzing around a light source in the early evening. However, they are not attracted to it: They are simply disoriented, so they get stuck flying around it.

Are Mosquitoes Attracted To UV Light?

You may have noticed that bug zappers often use UV light. The idea is to draw the mosquito in and effectively zap it so that it can no longer bother you. However, a bug zapper with UV light draws in many other flying insects, some of which are beneficial to the environment. Mosquitoes may fly to the UV light bug zapper, but to be effective, the bug zapper needs to have other features to lure the mosquitoes in.

The thing that attracts mosquitoes is carbon dioxide. They are drawn to their food source, which is blood. People and animals exhale CO2, and this is what mosquitoes are looking for. They are also drawn to body odor and sweat. You will find that an effective mosquito trap will use CO2 as a lure to get the mosquito into the trap. It may also have a UV light, but it will have the CO2 as well.

Do Red And Yellow Lights Repel Mosquitoes?

If you go to the light section at the store, you will find yellow or red lights that are sold to repel bugs. They recommend using them outdoors in your porch light. These lightbulbs do not repel mosquitoes, but they are dimmer so they disorient them less. They also make it more difficult for mosquitoes to see their target. You may find that you have fewer mosquitoes than you would with a brighter light, but it doesn’t repel them.

Mosquitoes can smell the CO2 when you exhale, so as long as you are outdoors breathing, they only need a little bit of light to find you. The most effective way to get rid of mosquitoes is to use a trap that lures them in with CO2 and kills them.

Are Mosquitoes Attracted To Blue Light?

Blue light, such as LED lighting, is another type of light that can be used. It’s a cooler type of light than standard light bulbs emit and it’s bright. Blue light tends to draw in more bugs and mosquitoes than warmer hues because it allows them to clearly see their meal.

Since blue is the preferred light color for mosquitoes, make sure to keep that in mind when looking for an efficient bug zapper or bug trap. The Mosquito Attract Light by Dynatrap does exactly that!

What Is The Best Light To Use To Get Rid Of Mosquitoes?

The best light to use to cut down on mosquitoes is a yellow light bulb. It won’t repel them, but it doesn’t attract them because the light is muted. Because it’s harder for them to see where they’re going, you won’t find as many mosquitoes on your porch as you would with an LED light or a standard lightbulb.

However, if you truly want to get rid of the mosquitoes, you need to use a CO2 mosquito trap. They are drawn to carbon dioxide and the smell of people or animals, and they will find you if you don’t break their breeding cycle and get rid of them with an effective trap. The Dynatrap Mosquito Catcher would be a good example.

What Happens When You Turn The Light On At Night?

How Mosquitoes Find Their Prey

When it’s dark outside, mosquitoes find shady places in the trees or shrubs to rest until dusk. The primary reason for this is that they can’t see in the dark to find their prey. When you turn the light on, not only can they see but they will detect your scent and the air you exhale. Mosquitoes have chemical, visual, and heat sensors that help them find their prey.

FYI: Some mosquitoes have a similar day and night rhythms like us humans. One example would be the Elephant Mosquito from the Toxorhynchites species. They probably won’t bother you at night (and don’t even bite humans).

Phototaxis

Although they’ll want to fly towards you, the light is so bright that it can disorient them. This is called phototaxis, and the mosquito can end up confused and flying around the light. The reason that mosquito traps use ultraviolet light along with CO2 to lure them into the trap, is that the UV light disorients mosquitoes the least, and it’s their preferred light source. It is more likely to entice them to come out after dark.

Dehydration

Although they prefer this type of light compared to others on the light spectrum, it doesn’t attract them. It’s simply a preferred method, so they are more likely to come out and look for food. Mosquitoes become dehydrated easily, which is why they avoid direct sunlight.

Conclusion

When you see a light on a porch at night, you will undoubtedly start to think that, similarly to other flying insects, mosquitoes are attracted to light. The light may draw them out of hiding, but it doesn’t exactly attract them.

Mosquitoes use light to travel to their prey. The brightness and closeness of the lightbulbs can confuse them. They can become disoriented and end up flying around the light in circles. Although this does happen, it’s not because they are attracted to the light.

The important thing to know about mosquitoes is that they are attracted to their prey, and they find it by sensing the CO2 that people and animals exhale. While the light can help them navigate to their meals, they are drawn to the CO2.
