German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and McGuffey's a four-season climate shaped by the Ohio River valley, with less lake-effect snow than Cleveland or Akron keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Older brick and hillside homes throughout Cincinnati, alongside Dayton-area suburban construction tied to the region's aerospace industry.
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.
