Mosquito treatments will be increased at Brunswick Lake Park to help prevent West Nile VirusMosquitoes trapped by the Medina County Health Department near Susan Hambley Nature Center at Brunswick Lake Park have tested positive for West Nile Virus, according to the Ohio Department of Health.

In response, the Medina County Health Department will conduct additional treatments in possible breeding locations around Brunswick Lake. Beginning today, health department staff will increase larvicide treatments in an effort to control future mosquito hatches. This includes treating catch basins with extended-release larvicide tablets and treating accessible marshy areas with a granulated formula larvicide.

The health department recommends that members of the public take the following personal protective measures to reduce the risk of being bitten by mosquitoes:

  • Apply a U.S. EPA-registered insect repellent when going outdoors.
  • Wear light-colored clothing, long-sleeved shirts or jackets, and long pants to protect against mosquito bites.
  • Consider avoiding outdoor activities during peak mosquito biting hours.

Mosquitoes become infected with West Nile Virus when they feed on infected birds. Infected mosquitoes can then spread the virus to humans and other animals when they bite, potentially causing serious illness.
