Key takeaways

  • Mosquitoes are drawn to natural signals your body gives off, especially heat, carbon dioxide from your breath, and even your body’s scent.
  • Things like darker clothing, alcohol consumption, and certain sweet scents can make you more noticeable to mosquitoes.
  • Reducing mosquito bites starts with simple steps such as removing standing water, wearing light-colored clothing, and limiting attractants.
  • Home remedies can help, but professional mosquito control is typically the most effective solution.

Anyone who has suffered through the pain and irritation of mosquito bites knows what troublesome pests mosquitoes can be. But what attracts mosquitoes to humans in the first place? The truth is, several different factors can make a person more or less attractive to mosquitoes. However, understanding what attracts mosquitoes to you can help you better prevent their painful, itchy bites.

Why do mosquitoes bite humans?

Believe it or not, only female mosquitoes bite. They have a proboscis, which is a long, tubular mouth that can puncture the skin and suck blood. Female mosquitoes feed on blood to get the nutrients needed to produce eggs. When they bite, they inject a small amount of saliva that keeps blood flowing, which is what causes itchy mosquito bites. In some cases, that saliva can also transmit pathogens that cause mosquito-borne diseases.

What attracts mosquitoes to humans?

Mosquitoes use thermal sensors and chemical receptors to help them find their next meal. The main thing that attracts mosquitoes to humans is a mix of signals your body naturally emits. It comes down to things like your breath, body heat, and natural scent. Some people just happen to send out stronger signals, which is why you might feel like a magnet for mosquitoes while others nearby get left alone.

Your blood

The warmth of your skin is a major factor in what attracts mosquitoes to humans. These pests use thermal sensors to find the heat radiating from your veins. This heat tells the female mosquito exactly where the blood is closest to the surface. Keeping cool is one of the best ways to help stay off their radar.

Your breath

Every exhale releases carbon dioxide, which acts as a long-range beacon. This gas can attract mosquitoes from over 30 feet away. If you are sipping a cold alcoholic beverage on the patio, you might be at higher risk. Alcohol can increase the amount of ethanol in your sweat and change your breathing pattern. These small changes make you a much more obvious target for any nearby pests.

Your smell

Your natural scent is one of the strongest attractants for mosquitoes. Sweat, skin bacteria, and body oils create a unique odor profile that mosquitoes can detect with ease. Scented products can add to this, especially sweet or floral perfumes and lotions, which may make you more noticeable.

Your clothing

Mosquitoes use their eyes to find targets from a distance. If you want to know what colors repel mosquitoes, look at light shades like white, tan, and pastel yellow. These colors do not absorb as much heat, helping you blend in. Darker shades like black, navy, and red tend to absorb more heat and stand out more clearly to a mosquito's eye.

Which blood type do mosquitoes like the most?

There is no single determining factor explaining why mosquitoes bite who they bite. Researchers have demonstrated that individuals with Type O blood are more likely to be bitten than individuals with Type A blood.* Your metabolism is also a factor, with its capacity to raise and lower your body temperature. Scientists have established that an individual's genetic makeup can account for 85 percent of the various factors that can attract mosquitoes to you.*

Why are mosquitoes attracted to me?

Are mosquitoes attracted to other species, like dogs?

Dogs and cats attract mosquitoes the same way humans do through breath, heat, and scent. Mosquitoes are opportunistic feeders, which means a mosquito’s diet is often whatever host is most readily available.

Some types of mosquitoes may be more attracted to you or your pet than others. For example, Aedes mosquitoes feed on humans and animals, such as dogs. Anopheles mosquitoes focus more on humans but can bite mammals, while Culex mosquitoes prefer birds but may also bite dogs and people.

What habitats are mosquitoes attracted to?

Mosquitoes are most active in warm, humid environments with access to standing water. Stagnant water is where mosquito breeding takes place, even in small amounts like bottle caps or clogged gutters. They also rest in shaded areas such as tall grass, shrubs, and under decks during the day, then become more active at dawn and dusk when conditions are cooler.

How to reduce your chance of mosquito bites

Reducing exposure starts with limiting what draws them in and making your space less inviting. Some people use home remedies for mosquitoes, such as citronella, peppermint, or lemongrass, since mosquitoes tend to avoid these smells, but they usually work best when combined with other methods. Here are some easy mosquito prevention tips that you can follow:

  • Remove standing water around your yard
  • Wear light-colored clothing
  • Use fans outdoors to disrupt their flight
  • Keep grass trimmed and reduce shaded resting areas

For stronger protection, professional mosquito control can target the source of the problem. Terminix offers advanced treatments that help reduce mosquito populations and protect your yard. With expert help, you can spend less time swatting and more time enjoying your outdoor space without constantly wondering what attracts mosquitoes.
