Mosquitoes will not only bite you. After sucking your blood, they will pee on you.

In a new paper published by Cornell University, keeping that "gotta go" feeling from being relieved may actually be one way to keep mosquitoes in check. Researchers identified a protein from the renal tubules of Aedes aegypti mosquitoes that's involved in promoting urination as they feed on blood. When mosquitoes consume and process blood meals, they must urinate to prevent fluid and salt overloads that can kill them.
