Mosquito traps have been placed in various locations to combat mosquitoes that carry West Nile virus. The traps, mounted inside boxes, use a fan to blow out and a hole to suck in the mosquitoes. Some of the caught mosquitoes have tested positive for the virus.

A wildlife biologist and Mosquito Identifiability Specialist is involved in the effort, using little white bricks to poison larvae in standing water. The bricks are tossed into storm drains where female mosquitoes lay eggs.

Further details about the mosquito control efforts are available from the source, including the use of these traps and bricks to prevent the spread of West Nile virus.
