Mosquitoes are not only attracted to the carbon dioxide that humans release, but also by our body heat. They sense the warmth of their prey and find them in complete darkness using an infrared sensor located on their antennae.

Mosquitoes have been known to see in the light. They use the light of the moon, sun, and stars to help them find humans. But how do mosquitoes find humans? Read more in detail here: can mosquitoes see in the light.

Mosquitoes are among the most irritating insects on the planet. They flutter about like huge pests, making their presence known.

Worse still, they have the potential to spread illness. The last thing anybody wants is to get bitten by a mosquito and develop a disease.

Knowing more about mosquitos and how they locate people might be useful knowledge. It may provide you with the key you need to keep mosquitoes at bay and enjoy your time outside without fear of unwanted guests.

Mosquitoes: What Are They?

Mosquitoes are those pesky little creatures that bite us and drink our blood. But how much do we truly know about them?

Mosquitoes are one of the most tenacious insects on the planet, with over 3,500 distinct kinds.

Both the female and male mosquitos eat on nectar, however the female mosquitos will suck blood from victims in order to get the blood they need to produce their eggs efficiently.

They eat at all hours of the day, and it is during this feeding period that mosquitoes transfer a broad variety of viruses, including some of the world’s most deadly.

Bites from Mosquitoes

Mosquitoes eat by sucking blood via their proboscis, the long needle-like component of their mouth. Some people mistake it for a tube. However, if you examine it closely enough, you will see that the mosquito’s mouth is really divided into six sections.

The maxillae and mandibles are essentially knives at the end of the proboscis, capable of piercing the flesh and skin of their prey and sucking out the blood. The two largest tubes in the proboscis operate when they strike a vessel.

Finally, the hypopharynx transports mosquito saliva while the labrum suctions blood. The saliva delivery is what keeps the blood from clotting.

Anyone who has been bitten by a mosquito can testify to the itchy, red lump that emerges on the skin as a consequence of the bite.

Where Do They Look for Humans?

When mosquitoes are seeking for a blood meal, they employ a number of signs to locate people and animals. The CO2 is a greenhouse gas. from our breath and our body heat are the first things they check for.

Recent research has also shown that their antennae include an olfactory receptor that can detect people. They achieve this by attracting mosquitos with the compounds found in human perspiration.

Let’s take a closer look at all of the variables at play and how mosquitoes could be drawn to humans.


Mosquitoes may detect human presence by looking for telltale indicators. Mosquitoes can see a host when it is within 50 feet (15 meters) of them, according to research. Even in the dark, this is true.

Visual cues are used by mosquitos as a signal, drawing them closer to the people they aim to bite. If a mosquito is within 50 feet of you in the dark, it will be able to see you without difficulty.

CO2 is a greenhouse gas.

Mosquitoes are also heavily drawn to the CO2 is a greenhouse gas. that we and other animals create whenever a breath is exhaled. Since we exhale quite a bit during the day, this can create a large amount of CO2 that winds up attracting the mosquitos.

What you may not understand is that elevated CO2 levels are an excellent method to locate people. This is why you may observe customs authorities using it at the border to look for suspected human trafficking and smuggling.

CO2 may even be utilized to locate persons trapped under the debris during disaster rescue attempts.

So it only makes sense that mosquitoes would use this as a way to track down humans (aka their food source). Mosquitoes can detect CO2 is a greenhouse gas. even if we wear heavy clothing and blankets as well.

Mosquitoes are attracted to this odor because they have finely tuned olfactory receptors that detect the smell of CO2.

Thermoelectric Attractors

Mosquitoes employ thermal attraction as their last means of locating their food supply. When they are approximately three feet away from someone, they can detect the source’s body heat.

They do everything else to come within range before turning to their thermal sensing to narrow the gap.

Researchers made two glass items and covered them with a chemical that enabled them to be heated to any temperature, according to a recent study. One was kept at ambient temperature, while the other was heated to the temperature of a normal human body.

When put in a wind tunnel, mosquitoes preferred the warmer of the two items.

So, even though CO2 detection is what draws them to the location, it will be the heat signature that takes them to their intended chevaliers.

Is Light Attractive to Mosquitoes?

Bright lights attract certain bugs, particularly moths. When it’s dark outside and the light is on, you can notice an accumulation of bugs on your back porch light. Is it, however, luring mosquitoes to the garden as well?

Mosquitoes, for the most part, avoid direct light exposure. This is because extended exposure to sunshine causes them to quickly dehydrate and perish. That isn’t to say that they completely shun light.

While sunshine will dehydrate them, not all light sources have the same effect. Mosquitoes are mostly evening insects.

To adequately explore the region, they will employ local light sources. They don’t perceive light in the same way that we do.

Artificial illumination, such as that from a porch light, may actually make mosquitoes’ nocturnal navigation more difficult. This may perplex them and cause them to lose sight of their food sources from the incorrect angles.

Because the light from the stars and the moon is so far away, this sort of light has very little effect on them. They may still maintain correct angles so that they can readily observe their food supply.

Use Smells They Despise

Using a fragrance that mosquitoes dislike is an excellent approach to get rid of them. There are various natural repellents on the market that have a pleasant scent and will keep those pesky little bugs out of your yard.

Lavender, basil, peppermint, eucalyptus, lemongrass, lemon balm, garlic, rosemary, and citronella are all good choices. They all have a pleasant, natural odor that hides the fact that they’re being used to keep mosquitos away.

Make use of a chemical repellent.

Using a chemical repellent specifically intended to keep mosquitoes at bay is perhaps the most frequent technique for homes to keep them at bay. This chemical repellent will not only protect them from biting you, but it will also keep them out of your yard.

You should look for products that have 30 percent to 50 percent DEET. According to research conducted by the Environmental Protection Agency, it is fully safe for current safety requirements when used appropriately, contrary to common assumption.

Simply use care while spraying it. Having dogs and young children, in particular, need additional attention, which is why so many people choose for a natural repellant (see the previous section).

Make use of an outdoor soap.

Some outdoor soaps have been designed expressly to keep mosquitoes at bay. You may bathe with them since they are fully natural and non-toxic.

Bathing with them will not only prevent you from sweating, but it will also keep insects at bay.

As you can see, one of their greatest features is their sense of smell, which they will utilize to locate out their food source across long distances. You may keep mosquitoes at away by removing some of the fragrances and replacing them with ones that they dislike.

Attempt Candles

There is a reason why you may have observed someone lighting candles on their patio or back porch. Candles, like essential oils, have a natural aroma that works well as a mosquito repellent.

Burn candles with citronella, lavender, or other popular insect-repelling aromas to keep insects out of your house while also enjoying the pleasant aroma. It’s a terrific technique to create atmosphere without emitting a strong chemical odor that might be irritating.

You should also clear out the candle wax from time to time. Some insects are attracted to the heat and may get stuck in the melting wax.

Mosquitoes can see in the dark. They use a special organ called the “Jacobson’s Organ” that is located on their antennae to detect heat and carbon dioxide. When they are near humans, mosquitoes will often fly into light sources until they find you. Reference: how do mosquitoes find you.
