MINNEAPOLIS, MN - The Metropolitan Mosquito Control District is

treating twenty thousand wetlands around the Twin Cities to try to

kill the pests, and to cut down on West Nile virus later this

summer.

The number of West Nile cases has increased each year in

Minnesota, up to 101 human cases last year. Human infection can

send victims to the hospital.

The Metropolitan Mosquito Control District has been in business

for 50 years, but the last seven have mostly been dedicated to

battling West Nile.
