KUTZTOWN, Pa. (AP) – A bad bug is making life miserable for some Pennsylvanian residents and business owners. The spotted lanternfly has emerged as a serious pest since the federal government confirmed its arrival in southeastern Pennsylvania five years ago this week. It sucks the sap from valuable trees and vines. It rains its clear, sticky, sugary waste onto pools and decks, driving exasperated homeowners indoors when they’re not too busy killing the fluttering buggers. The bug’s range is expanding.
