El Paso Health Department officials say there are three confirmed West Nile virus cases. These mark the first cases of the mosquito-borne illness this year. With monsoon season, rains mean thee chance for puddles to form and they are the perfect breeding ground for mosquitoes.

Here are a few reasons why mosquitoes might bite you:

If you breath heavily, like when you're exercising, you're just sending out a signal to the little blood-suckers.
Working out outside is a lot of fun, but mosquitoes can detect the increase in lactic acid in your body and it makes you a mosquito magnet.
There's nothing like a cold beer on a summer day, but you're not the only one who is going to enjoying that beer. Mosquitoes think you taste lovely after having a cold one, so be on the lookout for the little buzzy boozers.
Mosquitoes love Type O blood and if you have it, they want it. Type O will make you more susceptible to mosquito attacks.
This last one is pretty awful, but if you're pregnant, mosquitoes will completely dig you, so take precautions and ask your GYN which mosquito repellent you can use.

One of the best ways to avoid a mosquito bite is to insect repellent, wear long sleeves and long pants along with socks, and avoid being outside at dusk and dawn. Don't forget to make sure the screens on your windows don't have holes, and don't leave any standing water in flowerpots, gutters, pool covers and other spots around your home.
