German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Columbus Grove's a humid climate with hot summers and winters mild enough that snow cover is less consistent than up north keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. A mix of century-old Cincinnati neighborhoods and mid-century Dayton suburbs built around Wright-Patterson Air Force Base.
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.
