West Nile Virus Update

It’s that time of year! Cape Cod Mosquito Control reported their first positive detect from a batch of mosquitos collected in Sandwich on July 21, 2022. The risk level for transmission of West Nile Virus remains low across the state. The Massachusetts Department of Public Health publishes risk maps for transmission at the following link:…/massachusetts-arbovirus-update.

What can county residents do to reduce the risk of getting a mosquito-borne illness? Reducing standing water is a key…even a small amount of standing water can become a mosquito factory. Trash can lids, tarps on the ground, clogged rain gutters, flower pots- get rid of the water. Change out bird baths and pet water buckets weekly. Use an EPA registered repellent like DEET or picaridin. Avoid being outdoors during peak mosquito hours from dusk to dawn. And make sure window screens are free of holes.For more information see the Cape Cod Mosquito Control Project at
