Mosquito Report


The current vector index (estimate of West Nile virus risk to people) is 0. This page will be updated as more information is available. 

Even when the West Nile virus vector index is low or at zero, there is always some risk while mosquitoes are active—from spring up until the first hard freeze in the fall. Residents are urged to take precautions to avoid mosquito bites and drain standing water on their properties. Please see the West Nile Virus Factsheet for more information.
