It's not bad luck — it's your zip code. Humid continental/subtropical transition climate — hot, humid summers and cold winters with regular snowfall, typical of southeastern Pennsylvania. Large stock of pre-WWII architecture — Colonial-influence and stone Tudor homes are common; one of the older, more historic boroughs in the region. That's exactly what Carpenter ants, Subterranean termites, Stink bugs, Oriental cockroaches, Ticks, and Mice need to get inside. Waiting won't fix it. It just gives them more time to spread.
A one-size-fits-all spray doesn't cut it here. An older, mostly built-out borough (median housing dating to the late 1930s) with a mix of larger detached single-family homes and rowhomes/duplexes, meaning aging foundations are common. So before we write a treatment plan, we inspect first. Water, tree cover, open land, building age — it all factors in. You get a real diagnosis, not a guess.
