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 larvicide and spray program during the season that mosquitoes are most active, from late spring to early fall.  Recent tests conducted have produced positive West Nile Virus results.   

At this time, Mosquito Control is not aware of reported cases of West Nile Virus in humans or animals in York County.  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. 

Residents are encouraged to pick up Mosquito Dunks from the Waste Management Center, Public Works office or the Tabb Library.  This is a natural mosquito control product that is free of charge to citizens.  The dunks use a bacteria mosquito larva ingest that will kill them. The bacteria is mosquito specific and is harmless to other creatures. Each dunk treats 100 sq. ft. and lasts 30 days. A single dunk can be broken up and treat smaller areas.

It is also important for residents and businesses to regularly tip and toss any standing water on their property, especially in containers such as tires, flower pots, tarps, toys, and bird baths.

Residents can also request free yard inspections to identify areas containing standing water.  If you are interested in adding mosquito fish to your ornamental pond any other area of permanent standing water, they can be provided free of charge by contacting Mosquito Control. 

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 is by eliminating standing water around your homes. Mosquitoes lay their eggs in, or where there will be, standing water, and a bottle cap of water is all they need. Remember to Tip & Toss!

After every rainfall, tip out any standing water in flowerpots, planters, children’s toys, , buckets, tarps, corrugated downspouts, 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.

Also:

  • Dump bird baths so water isn’t standing in them for more than four days 
  • Clean out gutters
  • Remove piles of leaves out of ditches to keep water flowing
  • Keep vegetation cut low in shady areas to prevent resting 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
