West Nile Virus Catch Basin Program

Each year beginning in May, CMMCP applies larval control products to area catch basins for the control of Culex mosquitoes. This species of mosquito is implicated in the amplification of West Nile Virus (WNV) among the bird population and potential transmission of WNV to humans.

Catch basin treatments will done in the following priority order:

  1. Prior year WNV activity;
  2. Senior Centers and 55+ housing;
  3. Recreational areas;
  4. Schools (only if our products are included as part of their outdoor IPM plan);
  5. Neighborhoods;
  6. Industrial areas.

This program continues through the summer months, and may be restarted if WNV becomes identified in a specific area. Many factors (time of year, weather, location, etc) will play into our response if/when WNV is confirmed in a given area.

Area residents are reminded that containers and other debris in their yards may hold water and produce significant numbers of mosquitoes each week. Please help to reduce the mosquito annoyance and threat of disease by preventing water from collecting in these areas.

Please Note: Any adulticiding (spraying) in response to WNV and/or EEE viruses will be done in consultation with the local Board of Health and other local and state  authorities.
