Increased mosquito activity in Western Pa. spurred by recent rain, high humidity

PITTSBURGH — Recent rain showers and high humidity have set the scene perfectly for a jump in mosquito activity in Western Pennsylvania, according to our news partners at Trib Live.

That’s why Karen Poh, a postdoctoral researcher at Penn State University’s Department of Entomology, said she isn’t surprised there has been an uptick in mosquito activity in the region.

Mosquitoes lay eggs in water, she explained, and mosquito larvae require water to survive. So rainy weather and sitting water make for ideal mosquito breeding grounds.

Adam Witt, president of Witt Pest Management, said he has gotten hundreds of calls requesting help with mosquitoes. His company services Allegheny, Armstrong, Fayette, Washington and Westmoreland counties, among other Western Pennsylvania locations.

“I think there’s a lot more moisture, and mosquitoes lay their eggs in water,” he said, adding he has noticed a trend in more mosquito- related calls over about three years.
