Mosquitoes in York City and Springettsbury Township have tested positive for West Nile virus for the third time this year, the York County Mosquito Surveillance Program announced Wednesday.

The samples were collected Thursday, Sept. 12.

This is the sixth round of samples in York County to test positive for the virus in 2019, but the county is still far below the number of mosquitoes that tested positive for West Nile in 2018, said Lee Graybill, administrator for the county's mosquito surveillance program.

"At this time last year, we had over 600," he said. "Last year was a huge year and a record year for York County, and this year is very low in comparison."

Mosquito season will be over in another two or three weeks when the temperatures cool down, Graybill said.

In Springettsbury Township, samples collected July 29 and Sept. 6 tested positive, and in York City, samples collected Sept. 5 and Aug. 29 tested positive.

The York County Mosquito Surveillance Program and state Department of Environmental Protection have been testing additional samples and reducing larval populations in the those areas.

Graybill has collected other positive samples this summer from Conewago, Fairview and Manchester townships and Hanover.

The best way to control the mosquito population is for residents and property owners to clean up debris on their property and eliminate standing or stagnant water that collects in swimming pools, discarded tires or other containers, according to a news release.

York County residents should take precautions when spending time outdoors, such as wearing insect repellent or bringing a portable fan outside to keep mosquitoes away.
