"Performing a community-wide cleanup is the only way to eliminate most mosquito concerns," the release said. "Residents are urged to contact your local municipality to help promote cleaning up to reduce mosquito concerns and disease risk."

Residents are urged to inspect their yards and reduce clutter. They should also purchase mosquito control and repellent products, the release said.
