Mosquito spraying is conducted when mosquito traps indicate significant populations of specific mosquito species that are likely to carry West Nile virus. The public will be notified in advance when and where any spraying for adult mosquitoes will take place. Spraying usually occurs between dusk and early morning. Announcements will appear in the Public Opinion, on local radio stations, and on this website.

The following are some common sense measures that should be followed when mosquito spraying becomes necessary in your neighborhood.

  • If possible, remain inside whenever spraying takes place.
  • Keep children inside during spraying and for about an hour after spraying.
  • Close windows and doors and turn off your air conditioning (or set it to circulate indoor air) before spraying begins.
  • If you must remain outside, avoid eye contact with the spray. If you get mosquito spray in your eyes, immediately rinse them with water.
  • Wash exposed skin surfaces with soap and water if you come in contact with the mosquito spray.
  • Rinse homegrown fruits and vegetables thoroughly with water before cooking or eating.
  • Cover outdoor tables and play equipment, or wash them with soap and water after spraying.
  • Bring laundry and toys inside before spraying begins. Wash with soap and water if exposed to mosquito spray.
  • Bring pets inside and cover ornamental fish ponds to avoid direct exposure.
  • Consult your physician if you think you are experiencing health affects from the spraying.
