Mosquitoes do like some people greater than others, right here’s why:

All mosquitoes like carbon dioxide

Walker stated regardless of the kind of mosquito, all of them like one factor: carbon dioxide.

“All mosquitoes are going to look for carbon dioxide because everything that they could possibly be biting is going to breathe that out in large amounts,” Walker stated.

If you’re one of many people mosquitoes love, Walker recommends utilizing repellant, even in your garments.

‘There are two things you’re making an attempt to do. One of them is to disguise your scent,” Walker stated. “Another thing is to actually smell bad to the mosquito.”

However, past your particular person, the most important mosquito attractant is standing water.
