German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Bakersfield's a climate defined by extreme summer heat — well over 100°F is common — and cool, foggy winters keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. A mix of older farmworker and agricultural-town housing and newer suburban tract construction, most on slab foundations built for heat rather than cold.
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.
