We monitor mosquito breeding areas during the summer mosquito breeding season to look for mosquitoes that carry diseases that can make people sick.
There is no evidence to suggest that COVID-19 can be spread by mosquito bites.
West Nile virus is spread to humans through the bite of an infected mosquito. Mosquitoes get infected with West Nile virus by feeding on infected birds. Crows and blue jays are known to get sick and die from West Nile virus.
The WI Department of Health Services is no longer testing crows and blue jays for West Nile virus and the Dead Bird Reporting Hotline is now closed. If you find a sick or dead bird please visit the Wisconsin Department of Natural Resources (DNR) Wildlife Health Program website for information about which species of birds should be reported to them for wildlife health-related investigations.
Most individual dead birds do not need to be reported or collected, and can be discarded. To safely dispose of a dead bird, use gloves or an inverted plastic bag to place the carcass in a garbage bag, which can then be placed in the regular trash. Wash your hands with soap and water for at least 20 seconds. Dead birds should not be handled with bare hands.
