Pittsburgh area pest management guidelines conform to research published by Penn State Extension and the Pennsylvania Department of Agriculture.
Appalachian Terrain & Foundation Moisture Drivers
Pittsburgh's steep hillside topography and three river valleys result in heavy ground moisture accumulation against hillside foundations. Large black Carpenter ants (*Camponotus pennsylvanicus*) excavate galleries in damp wall framing, while Eastern Subterranean termites tunnel up stone basements. Winter brings house mice seeking warmth in ceiling joists.
