German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Abell's a four-season climate with real winter cold and snow, and hot, muggy summers keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Dense rowhouse and multi-family housing in the urban core, alongside single-family suburban homes further out, most with basements.
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.
