Sewage Breeds Bigger, Faster Mosquitoes

Add this to the list of things that make sewage stink: Mosquitoes thrive on it.

A new study, presented at the meeting of the Ecological Society of America in Albuquerque, found far more mosquitoes in sewage-contaminated streams than in clean ones. Sewage-bred mosquitoes were also bigger and faster than those in purer waters.

Mosquitoes carry West Nile virus and other dangerous diseases. The new study suggests that sewage is a public health hazard in more ways than one.
