Do mosquito bleed

Mosquito's don't just bleed by themselves, they have to get blood from someone. If you kill a mosquito while it's on you getting blood, it may leave blood on you. Also if you kill one that's on you but hasn't done anything to you yet then it's most likely another person's blood. So yes, they bleed but it's not their blood. Look at the bright side at least they don't live long without blood.
