Cockroaches need three things to establish a colony: food, water, and warmth. Mardela Springs's housing stock gives them exactly that. Wood-frame homes on crawl spaces are common here, given the high water table typical of the Eastern Shore. Combined with Mardela Springs's climate — a humid subtropical climate moderated by the Chesapeake Bay, with hot, humid summers and mild winters — indoor cockroach pressure rarely lets up on its own.
We start with an inspection to identify the species and the source — sanitation issue, moisture problem, or entry point. Treatment centers on gel bait placed in cracks, voids, and under appliances, not broadcast spraying, since German cockroaches in particular have developed resistance to many surface sprays. A follow-up visit confirms the bait is working and the population is dropping.
