Mosquito Control

Multiple West Nile Virus positive mosquitoes samples were collected from communities in Essex, Middlesex, and Suffolk Counties indicating that the risk for human infection from WNV has increased to moderate in the counties of Arlington, Chelsea, Everett, Lynn, Malden, Medford, Melrose, Revere, Saugus, Somerville, Stoneham, Wakefield, Winthrop and Winchester. Additional findings in neighboring towns are likely to occur within the next few weeks. The current warm weather and pattern of precipitation events will continue to support increased mosquito populations, especially those most likely to spread West Nile Virus. Residents should be urged to avoid mosquito bites regardless of where they live.

Mosquito Bite Prevention Tips include:

  • Teach children to be aware of mosquito avoidance habits
  • Pick a pest repellent with an EPA approved active ingredient (DEET)
  • Use long sleeves to cover up when possible
  • Remove standing water around your home to reduce mosquito populations
  • Repair window and door screens

Remember the 4D's


  • DEET: Use it every time you go outside, reapply as needed and follow directions when using together with sunblock.
  • Dawn and dusk: Mosquito's are hungriest at these hours. Make sure to use DEET and dress accordingly.
  • Dress: Tuck in pants and use long sleeve shirts. Light colored clothing will help you spot ticks a little easier.
  • Drain: If you have any standing water around your home, yard drain it. Standing water attracts mosquito's.
