There are some biological reasons why mosquitoes are more attracted to some people more than others.

Thats because mosquitoes are selective insects, and some people are more likely to get bites than others.

These cues let them know they are going to a blood source, Day said.

Perhaps CO2 is the most important.

The more you give off, the more attractive you are to these arthropods.

But what separates us from the nonliving entities that give off carbon dioxide, like cars?

Mosquitoes look for primary cues in conjunction with what Day calls secondary cues.

Lactic acid is released through the skin, signaling to mosquitoes that we are a target, Day said.

Mosquitoes also have other qualities that help them pick up on secondary cues.

They are able to contrast you with the horizon, so how youre dressed matters.

A mosquito also takes in tactile cues once it has landed on you.

Body heat is a really important tactile cue, Day said.

That comes into play with genetic differences or physiological differences.

That means those whose temperatures are a little higher are more likely to get the bite.

Being pregnant or being overweight also increases metabolic rate.

Of course, drinking outside is a popular summer and fall activity.

There are very, very few species that are active in the middle of the day.

They are very selective.

Sunrise and sunset are when youll see peak activity.

Switching your early morning run to an after-work run could help here.

Roughly 5% DEET sprays gives you 90 minutes of complete coverage.

DEET is the most effective, Piliang said.

Take a shower later to wash it off, and put on just a little bit.

Always read the directions on a spray before using it, and help children apply products by following theU.S.

Centers for Disease Control and Preventionguidelines.

Instead, keep the fan on or hang out in a breezy area.

Mosquitoes cant get around very much, especially in wind, Piliang said.

you’re able to run a fan to keep air moving.

If you do end up with a bite, you may or may not be bothered.

If it is itchy, the worst possible thing you’re able to do is scratch it.

If you do, then more histamine is released and it gets itchier, she said.

If you scratch it, youre also more likely to break skin.

you might get bleeding, scabs and put yourself at risk for infection and scarring.

Even a drink with ice on it will help relieve itch immediately.

It can counteract the reaction a bit.
