Do Mosquitoes Get Attracted to Light?

Mosquitoes are common pests that often cause annoyance and irritation when we are outside. Many people use various methods to keep mosquitoes away, such as applying repellent or using mosquito nets. However, there is a common belief that mosquitoes are attracted to light. This raises an interesting question: do mosquitoes get attracted to light? In this discussion, we will explore this topic and look at some scientific explanations to understand whether mosquitoes are actually attracted to light or not.

Understanding Mosquitoes

Mosquitoes are found in almost all parts of the world. They are notorious for their itchy bites, which can cause illnesses such as malaria, dengue fever, and Zika virus. Understanding their behavior is essential to controlling their population and preventing the spread of these diseases.

Mosquito Behavior

Mosquitoes are attracted to humans and animals by the carbon dioxide we exhale, body heat, and sweat. They use their sense of smell to locate their hosts from a distance of up to 50 meters. Once they have found a host, they land on the skin and use their proboscis to pierce the skin and feed on blood. They are also attracted to certain colors, such as black and red, and certain odors, such as perfumes and sweat.

The Science Behind Light Attraction

One key takeaway from this text is that mosquitoes are attracted to humans and animals by carbon dioxide, body heat, and sweat. While they are attracted to ultraviolet light, they are not attracted to visible light in the same way. Light traps can be effective in controlling mosquito populations, but they should not be relied upon as the sole method. To avoid mosquito bites, it is best to avoid being outside during their peak feeding times, wear protective clothing, and use insect repellent. Regular cleaning and good hygiene can also help in avoiding mosquito bites.


Phototaxis is the scientific term for an organism’s attraction to light. Many insects, including mosquitoes, exhibit positive phototaxis, which means they are attracted to light sources. Scientists believe that this behavior is linked to the insects’ navigation system, as they use the position of the sun to navigate during the day.

Ultraviolet Light

Mosquitoes are attracted to ultraviolet light, which is emitted by the sun and artificial light sources such as fluorescent bulbs. Ultraviolet light is invisible to the human eye but is highly attractive to mosquitoes. In fact, researchers have found that mosquitoes are more attracted to ultraviolet light than any other type of light.

Visible Light

While mosquitoes are attracted to ultraviolet light, they are not attracted to visible light in the same way. Some studies suggest that mosquitoes are more attracted to darker colors, such as black and red, but this is still a topic of debate among scientists.

The Truth About Mosquitoes and Light

Light Traps

Many people use light traps to control mosquito populations. These traps use ultraviolet light to attract mosquitoes, which are then trapped and killed. While these traps can be effective, they are not a foolproof solution. Mosquitoes are attracted to many things, including carbon dioxide, heat, and sweat, so a light trap may not be enough to control a large mosquito population.

Avoiding Mosquitoes

If you want to avoid mosquitoes, it is best to avoid being outside during their peak feeding times, which are typically dawn and dusk. You should also wear long sleeves and pants and use insect repellent containing DEET or other approved ingredients. Mosquitoes are attracted to sweat and body odor, so showering regularly and wearing clean clothes can also help.

FAQs for “Do Mosquitoes Get Attracted to Light?”

Do mosquitoes get attracted to light?

While many insects, such as moths and flies, are attracted to light, mosquitoes are not primarily drawn to light. In fact, mosquitoes use other cues, such as body odor, exhaled carbon dioxide, and heat to locate their prey.

Why do some people use bug zappers to kill mosquitoes?

Bug zappers are not an effective means of mosquito control as mosquitoes are not attracted to light. Instead, bug zappers only attract and kill insects that are naturally drawn to light, such as moths and beetles.

Can using light-colored clothing help reduce mosquito bites?

Wearing light-colored clothing can help reduce mosquito bites by making it more difficult for mosquitoes to locate their prey visually. However, mosquitoes are primarily attracted to body odor and carbon dioxide, so simply wearing white or light-colored clothing will not prevent all mosquito bites.

What types of lights do mosquitoes prefer?

Mosquitoes are not drawn to specific types of lights. In fact, studies have shown that mosquitoes are more attracted to dark-colored objects than to light-colored objects, as dark colors retain more heat and carbon dioxide.

Are candles or torches effective for repelling mosquitoes?

Candles and torches that contain certain essential oils or chemicals, such as citronella or DEET, can help repel mosquitoes. However, the effectiveness of these products is limited and may vary depending on the individual and the environment. Mosquitoes are ultimately drawn to specific odors and body heat, so using candles and torches alone may not provide complete protection against mosquito bites.
