Crews targeting city sewers, drains to halt West Nile | News
GRAND RAPIDS (WZZM) - Packets of biological larvicide aimed at killing the mosquitos that spread West Nile virus have been distributed in southeast side neighborhoods of the city.
Environmental services workers placed them in storm water catch basins Tuesday and will continue the work Thursday. Mike Lunn with the city said the bacteria pellets "dissolve in the sump of the catch basin, the bacteria come out and they kill the larva of the mosquitos."
The area being treated is bounded by Breton to the east and Division to the west and by 32nd Street to the south and Hall to the north.
Statistics from state health officials show most incidents of the disease are occurring in established urban areas in Grand Rapids and Detroit. These are areas that tend to have high numbers of the catch basins one official Wednesday called "mosquito factories."
