Mosquitoes in Houston can carry serious illnesses like West Nile virus and other diseases. The MVC Division monitors disease activity and treats areas before problems grow. Knowing what's happening in your neighborhood helps you protect your family.
The Harris County Commissioners Court is the governing body of Harris County, Texas. Led by the County Judge and four precinct commissioners, the court sets the county budget, tax rate, and policies affecting public health, infrastructure, flood control, and justice for over 4.7 million residents.
The division tracks disease activity, maps proposed treatment areas so you can stay informed, and carries out mosquito control treatments overnight. You can view the treatment map online and report any map problems by email.
