German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and White Castle's a Gulf South climate defined by extreme humidity, long hot summers, and a real hurricane season keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. A mix of older raised Creole-style homes and newer slab construction, with elevated foundations common given the area's flood risk.
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.
