We love when you work up a sweat.
You think weâre drawn by the aroma of your âsweet blood,â but itâs really the carbon dioxide you exhale that makes us beeline toward you. The harder you breathe, the more CO2 you emit, so youâre especially attractive after a jog.
Hate getting bitten up?
Blame the ladies. We donât like to admit this, but male mosquitoes do not eat human blood: They get all their nutrition from plant nectar. We females need your blood, which contains a protein that helps our eggs develop. After we have a blood meal, we can lay anywhere from 100 to 400 eggs.

So do some of us. Itâs crazy, but we can tell when youâve been drinking because your skin chemistry changes, and it lures us in.
Smelly feet are simply delicious.
In fact, scientists have shown that we find your tootsies ten times more alluring than Limburger cheese (but really our favorite body part is your hand).
To evade us at a party, donât be a wallflower.
When we smell a huge mass of carbon dioxide, we fly toward it; after we get there, itâs easier to attack the people on the perimeter of the group than those smack-dab in the center.
If your homeâs landscaping is well tended, we wonât like it as much.
like to hang out in thick, overgrown vegetation. The darker and more
humid, the better. If you keep your lawn mowed, pool skimmed, and bushes
trimmed, your backyard wonât be very appealing. Removing puddles of
stagnant water is also a great way to repel usâthatâs where we like to
lay our eggs.
Weâre thrilled when you buy DEET-free repellent.
DEET, along with picaridin, is among the stronger types that help keep us away. Each type blocks different
receptors that allow us to track you down. Weâre also not big fans of
lemon eucalyptus and the compound IR3535, although these are a little
weaker than DEET and picaridin.
Got those CO2-emitting traps in your yard?
Great! You may think youâre outsmarting us with these
devices, which emit carbon dioxide to lure us into a trap. But they may
attract more of us than they are able to trap, increasing our
presence in your yard. UV bug zappers arenât effective either: Only a
fraction of the pests they kill are mosquitoes.
If youâre a woman whoâs expecting, you emit more carbon dioxide and your abdomen has a higher temperature than when youâre not pregnant, drawing some of us right to you. Sorry, baby.
When it comes to West Nile, end-of-summer bites may do more harm.
Itâs simple logic: We
bite birds who have the West Nile virus; then we bite humans and spread it. By summerâs end, weâve had more chances to bite infected birds.
