Introduction
If you’ve ever been outside with a group of friends or family and noticed that mosquitoes seem to bite you far more than everyone else, you’re not imagining things.
Many homeowners across Central Ohio including Columbus, Dublin, Powell, Westerville, and Delaware notice that some people in a group seem to attract mosquitoes much more than others.
The reason for this comes down to how mosquitoes locate their targets. Mosquitoes use a combination of body heat, carbon dioxide, scent, and other biological factors to choose who they bite.
Understanding why mosquitoes are attracted to certain people can help homeowners reduce bites and better protect outdoor spaces around their homes.

How Mosquitoes Find People
Mosquitoes rely on several sensory cues to locate humans. They can detect:
- Carbon dioxide from breathing
- Body heat
- Body odor
- Skin bacteria
- Movement
Female mosquitoes use these signals to find hosts for blood meals, which they need in order to produce eggs. Once a mosquito detects carbon dioxide in the air, it begins searching for the person producing it.
Carbon Dioxide Is the Biggest Mosquito Attractant
One of the primary ways mosquitoes find humans is by detecting carbon dioxide (CO2). Every time you breathe, you release CO2 into the air. Mosquitoes can detect this gas from over 100 feet away.
People who produce more carbon dioxide tend to attract more mosquitoes. This includes:
- Adults (compared to children)
- Larger individuals
- People who are physically active
This is why people who are exercising outdoors often notice mosquitoes swarming around them.
Body Heat and Mosquito Attraction
Mosquitoes are also attracted to body heat. After detecting carbon dioxide, mosquitoes use heat sensors to locate warm areas of exposed skin.
People who have higher body temperatures may attract mosquitoes more easily, including:
- Individuals exercising outdoors
- People sitting in warm environments
- People who naturally run warmer
Warm summer evenings in Central Ohio create ideal conditions for mosquitoes to locate hosts quickly.
Body Odor and Skin Chemistry
Another major factor in mosquito attraction is body odor and skin chemistry. Everyone’s skin contains bacteria that produce unique scents. Certain compounds produced by these bacteria can make some people more attractive to mosquitoes.
Researchers have found that mosquitoes are particularly attracted to people who produce certain skin chemicals, including:
- Lactic acid
- Ammonia
- Uric acid
Blood Type May Play a Role
Some studies suggest mosquitoes may prefer certain blood types. Research has shown that mosquitoes may be more attracted to individuals with Type O blood compared to other blood groups.

Why Mosquito Problems Are Worse in Some Yards
Even if mosquitoes are naturally attracted to certain people, yard conditions often determine how many mosquitoes are present in the first place. Backyards that contain mosquito breeding areas may produce large mosquito populations.
Common mosquito breeding conditions include:
- Standing water
- Clogged gutters
- Bird baths
- Decorative ponds
- Shaded landscaping
- Dense shrubs
- Tall grass
Homes in suburban areas like Dublin, Powell, and Westerville often contain landscaping and moisture conditions that allow mosquito populations to grow.

How to Reduce Mosquito Bites in Your Yard
Homeowners can reduce mosquito activity by making their yards less attractive to mosquitoes. Helpful prevention steps include:
- Remove standing water: Empty containers, clean gutters, and eliminate water sources where mosquitoes may lay eggs.
- Maintain landscaping: Trim shrubs and keep grass short to reduce mosquito resting areas.
- Improve drainage: Low spots that collect water can become mosquito breeding zones.
- Use outdoor fans: Mosquitoes are weak fliers and often avoid strong airflow.
Why Professional Yard Treatments Help
In areas where mosquito populations are high, homeowners may benefit from professional yard protection treatments. Professional pest control services can help reduce mosquito activity by:
- Identifying mosquito breeding areas
- Treating shaded resting zones
- Reducing mosquito populations around the yard
- Protecting outdoor living spaces

Why do mosquitoes seem worse at night?
Many mosquito species are most active during dusk and evening hours, when temperatures are cooler.
Are mosquitoes attracted to sweat?
Yes. Sweat contains chemicals such as lactic acid that mosquitoes can detect.
Can you stop mosquitoes from biting you?
While it’s difficult to prevent bites entirely, reducing mosquito populations around your yard can significantly lower bite activity.
