Not people, Mosquitoes.
People don't usually kill the males, because they don't bite you...right?
But through reasoning...Males allow the Females to reproduce, so therefore, Not killing the Males will allow for a possible mosquito to spawn AND BITE YOU, or someone you love and care about.
Just because they don't bite you, doesn't mean you're not going to get bit.
So, fellow bug haters, do not only kill the ones that are trying to suck the precious blood from your body...but kill the males as well, for they are just as much a part of the enemy.
On a further note, Wearing jeans in the summer (although hot) will reduce the amount of places they can possibly bite you. But that doesn't mean they can't bite through your T-shirt, so be careful. Evolution doesn't always work to our advantage. Thicker, Longer Needles are growing on the new batches of mosquitoes every year. SO KILL THEM, KILL THEM ALL!!!!
