Mosquito Pool Tests Positive for West Nile Virus

York County Mosquito Control Division routinely samples mosquitoes collected throughout the County and tests for common mosquito-borne illnesses. Mosquito Control also conducts a comprehensive larvacide and spray program during the season that mosquitoes are most active, from late spring to early fall. One mosquito pool recently collected in Lower York County has tested positive for West Nile Virus.

At this time, there are no reported cases of West Nile Virus in humans or animals in York County that the County is aware of. The County plans to continue testing and spraying efforts. Mosquito Control recommends the use of insect repellent and long sleeves/pants to cover exposed skin.

For more information about West Nile Virus, please visit the Virginia Dept. of Health website. If there are concerns about symptoms in someone who has recently experienced a mosquito bite, please contact a medical provider.

Tip & Toss

Mosquito Control reminds citizens that the best way to protect our community from mosquitoes is to prevent them from breeding. One of the most effective ways of preventing the spread of mosquito-borne viruses is controlling the mosquito population by eliminating standing water around your homes and in your yards. Mosquitoes lay eggs in water, and a bottle cap of water is all they need. With the rain we’ve experienced lately, this is a perfect time to remind York County to Tip & Toss.

After every rainfall, tip out any standing water in flowerpots, planters, children’s toys, wading pools, buckets and anything else around your yard that can hold water. If it holds water and you don’t need it (old tires, bottles, cans), toss it out. Make sure water storage containers, such as rain barrels and buckets, are tightly covered or sealed to prevent mosquitoes from laying eggs in the water.

  • Clean out gutters
  • Remove piles of leaves
  • Keep vegetation cut low to prevent landing sites for adult mosquitoes
  • Citizens are encouraged to cleanup yards and communities to prevent mosquitoes from breeding in roadside trash
  • Keep doors shut and cover windows with screens, and repair or replace any screens with holes in them
  • Use insect repellent containing DEET
