Why Are Mosquitoes Attracted to Light?

Why Are Mosquitoes Attracted to Light

If you’ve ever wondered why mosquitoes are attracted to light, you’re not alone. Scientists have discovered that mosquitoes are attracted to certain colors, including blue-hued light and yellow light. Carbon Dioxide is another substance that attracts mosquitoes. Here’s what you need to know to reduce your mosquito-infesting risk. This substance is produced by our bodies and reaches the ground through our breath.

Blue-hued light

While the sun’s ultraviolet rays can attract mosquitoes, the opposite is true of mosquitoes. Generally, blue-hued light attracts mosquitoes, while yellow and red-hued light repels them. However, this does not mean that all kinds of lights attract mosquitoes. In fact, yellow and red-hued lights repel them just as well.

Mosquitoes are attracted to a specific wavelength of light, but it is still unclear how these wavelengths influence their behavior. Previous studies have suggested that mosquitoes may prefer certain colors in order to stay away from human-generated light. However, if you’re interested in creating a repellant or mosquito trap, knowing which colors attract hungry insects will give you a leg up on creating an effective one.

Yellow light

Bug zappers are a common outdoor lighting solution. While these devices do attract some insects, they tend to attract mosquitoes and other biting insects. This is especially true during the day when these insects are most active. Unlike these invasive pests, however, the zappers’ yellow light does not affect people or pets. And, since dead bugs can be harmful, it is best to avoid using bug lights in your home. Instead, look into a new type of outdoor lighting.

LED lights emit very little ultraviolet light. The yellow light that they emit is less appealing to flying insects. In fact, yellow LED lights are more repellent than blue ones. You should look for a yellow-filtering light bulb for outdoor lighting. Some of these bulbs have special filters to reduce the UV and blue light that attract mosquitoes. You can also use special mosquito-repelling lights, such as Orkin.

Warmer light

There are various ways to deter mosquitoes. In the first place, try avoiding the use of fluorescent lights. These emit ultraviolet light that mosquitoes are naturally drawn to. However, you can still avoid using blacklight in some instances. If you do, use a yellow light instead. This light has a higher UV content than warmer lights. Furthermore, avoid using outdoor lights that emit blue light, as these have high levels of blue light and are ineffective against mosquitoes.

Bug zappers do not work, because they are not likely to kill mosquitoes. LED lights are a great solution, since they are energy-efficient and emit a warm yellowish light. While some insects are drawn to UV light, mosquitoes seem to be attracted to warmer hues. Unlike our eyes, mosquitoes are blind to red and orange light. As a result, it is difficult to detect these colors.

Carbon Dioxide

Mosquitoes are attracted to many things, from light to carbon dioxide. The carbon dioxide produced by a human’s breath tells them that an animal is nearby. This information can help them find their prey, so when you see a mosquito flying in your direction, try to stay indoors. If you do get bitten, try to get inside as quickly as possible. The carbon dioxide you release can attract more mosquitoes than you’re aware of.

Researchers believe the chemical is responsible for this phenomenon. Mosquitoes can detect carbon dioxide 100 feet away and it triggers their visual system. Because they can recognize the color of human skin, they can identify individuals within a few feet. This research is in line with previous studies that show that mosquitoes follow the CO2 trail to a source of food. The scientists were able to observe this behavior by monitoring the flight paths of 1.3 million mosquitoes.

Incandescent light

While researchers haven’t yet determined why incandescent light is attracted to mosquitoets, they have established that some of them are drawn to blue or green light. The light produced by incandescent bulbs is the closest to the color of natural sunlight to our eyes. However, blue LED light attracts far fewer mosquitoes than incandescent light. The results of this study are inconsistent and may be influenced by the phases of the moon.

The oldest types of household light are incandescent bulbs. These bulbs are attracted to mosquitoes and other insects because they produce a neutral light. However, specialized bug lights are designed to attract less insects. Yellow or red bug lights are effective because they do not attract phototactic insects. Therefore, they are the preferred lighting option for mosquitoes. And if you live in an area with a lot of mosquitoes, incandescent light may be the best option.


Bugs and moths are attracted to LEDs for several reasons. Firstly, they love to swarm around light sources, especially as the seasons change. Secondly, they can judge the direction of the moonlight from long distances, so they are attracted to light in this color. While these are obvious benefits, the question remains – do LEDs really attract mosquitoes? If so, then the answer is a resounding yes.

Insects are drawn to light, and they seek heat in order to navigate. Since LED lights are not hot, they may look at them as a different color spectrum, which is not the case for insects. Moreover, LEDs produce enough warmth to attract mosquitoes but are not hot enough to burn them. LED lights are a good choice for outdoor areas. But there are some important things to consider before installing an LED light.
