Chester County Health Department (CCHD), in partnership with PA Department of Environmental Protection (PA DEP), continues to conduct mosquito surveillance throughout Chester County during the summer of 2021. One mosquito carrying West Nile Virus has been detected in West Whiteland Township.
CCHD’s Mosquito Borne Disease Control Program will continue to conduct mosquito surveillance and larval control for the remainder of the summer season, especially in areas where WNV positive samples occur. No Ultra Low Volume (ULV) adulticide spray applications are scheduled at this time.
What you can do:
In order to reduce breeding grounds for mosquitos, it is wise to inspect your yard and spend time to clean up, reduce yard clutter, and dump out any sources of stagnant water. Performing a community-wide cleanup helps reduce mosquito populations and avoid widespread chemical spraying.
Many of the most common mosquito species in residential areas come from artificial containers left behind by people. Artificial containers can be something as small as a bottle cap and as large as a swimming pool. Additional containers such as tires, buckets, and tarps are preferred by mosquitoes because other predators found in nature which would prey on mosquito larvae are not present. During periods of drought, these containers continue to hold water and produce mosquitoes. One bucket or tire in someone’s backyard can produce hundreds to thousands of mosquitoes in a year.
Mosquitoes can complete their life cycle within five to seven days during May-October. Residents are encouraged to use mosquito repellents when spending time outside. Individuals who don’t like to use repellents can use an electric fan outside while on a porch or patio. Mosquitoes don’t like the wind and the fan can help keep them away. As a last resort, residents can also purchase insecticides from garden centers and hardware stores to apply in their own yard, but need to be sure to follow the label instructions.
