If you’re getting bitten by mosquitoes when you’re on or near water, it’s usually because many mosquito species breed in or around standing water. Lake shores, ponds, marshes, slow-moving streams, and even puddles can be mosquito hot spots.

A few reasons they seem especially attracted to you:

• Mosquitoes are abundant near water because that’s where they lay eggs.
• They are attracted to carbon dioxide you exhale.
• They can detect body heat and certain chemicals in sweat.
• Some people naturally attract more mosquitoes than others due to genetics, body odor, or blood type.
• Mosquitoes are often most active around dawn and dusk, which are common times for water activities.

To reduce getting bitten:

• Use an EPA-approved insect repellent.
• Wear long sleeves and pants when practical.
• Avoid standing water near where you spend time.
• Use fans when sitting outdoors—mosquitoes are weak fliers.

If you’re being bitten much more than others around you, that’s actually pretty common and doesn’t necessarily mean anything is wrong; some people simply produce scents that mosquitoes find more attractive.
