You probably know that a common mosquito-control action advised by public health experts is to empty water containers around your yard to help limit mosquito activity. This is because certain kinds of mosquitoes — permanent water mosquitoes, as opposed to floodwater mosquitoes — like to lay their eggs in stagnant water. If the water evaporates before the eggs hatch and the larvae complete their life cycle, they die.

Hooray.

One of the most common permanent water mosquitoes is the southern house mosquito, known scientifically as Culex quinquefasciatus, which is a carrier of St. Louis Encephalitis and West Nile Virus.
