WOODBRIDGE, Va. — Mosquitoes collected in Woodbridge during the month of June 2012 by the Prince William Mosquito Control Program have tested positive for the West Nile Virus.
Mosquito testing is used to determine periods of greater risk of contracting West Nile Virus. The wide occurrence of positive mosquitoes indicates there is an increased risk of contracting the virus across Prince William County. Mosquitoes will continue to be trapped and tested regularly from sites throughout Prince William County. The County’s Mosquito Control Program has performed intensive treatment in the vicinity of the positive mosquito pools to kill adult and larval mosquitoes, and will continue larval control throughout the County and possibly conduct an adulticide spray based on future positive trap numbers.
