German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Bellvue's a climate shaped by the nearby Rockies, with sudden weather shifts and generally low precipitation keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Housing spans mid-century ranch homes to newer suburban subdivisions throughout this fast-growing corridor.
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.
