Are Mosquitoes Attracted To Light?
It’s common to see moths and other insects swarm around lights at night, which leads many to wonder if mosquitoes behave the same way. While mosquitoes may occasionally fly near light sources, they aren't strongly attracted to light like moths are. Instead, they rely on other cues to locate humans and animals.
Still, different types of light can affect how mosquitoes behave. Let’s take a closer look at whether UV or blue lights actually make a difference.
Are mosquitoes attracted to UV light?
Despite their popularity, bug zappers and other UV light traps are not very effective for mosquito control. Mosquito traps that rely on light alone usually catch very few mosquitoes. They become more effective when combined with carbon dioxide or scent attractants that mimic human cues.
Are mosquitoes attracted to blue light?
Some people wonder if mosquitoes are drawn to blue light or other colors. Blue light, often produced by LED bulbs, tends to attract more mosquitoes than warmer-colored lights, but it still isn’t the main factor that guides them.
What attracts mosquitoes?
Mosquitoes don’t rely on light to find their targets. Instead, they use a combination of sensory cues that help them locate warm-blooded hosts like humans and animals. Understanding what draws mosquitoes can help you take better steps to avoid bites and reduce their presence around your home.
Some of the most important factors mosquitoes use to zero in on you include:
-
Carbon dioxide: Mosquitoes can detect the carbon dioxide you exhale from up to 100 feet away. This is often the first signal that alerts them to a nearby host.
-
Body heat: Once they sense carbon dioxide, mosquitoes use heat sensors to locate the warm skin beneath your clothes.
-
Body odor and sweat: Chemicals released through sweat and natural skin oils, such as lactic acid and ammonia, attract mosquitoes and help them distinguish between different people.
Mosquito Prevention & Control
While mosquitoes may respond to certain types of light, many homeowners prefer yellow bulbs for outdoor use, as they tend to attract fewer insects overall. These bulbs emit light at a wavelength that’s less noticeable to mosquitoes, making them a helpful, though limited, deterrent.
However, switching bulbs alone won’t stop mosquitoes from biting or gathering near your home. For more reliable protection, contact an Orkin Pro to create a custom mosquito control plan tailored to your property.

Mosquitoes don’t sleep like humans but enter periods of rest and reduced activity during the day. They are most active during dawn and dusk.
Mosquito coils can effectively repel or kill mosquitoes when used outdoors in areas with minimal wind. However, they should not be used indoors due to potential health risks.
Most mosquitoes are small, measuring between 0.15 and 0.4 inches in length.
