German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Floris's a climate shaped by the Mississippi River valley, with more consistent precipitation than the drier western part of the state keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Older brick and wood-frame homes are common throughout this region's historic manufacturing river cities.
Treatment starts with locating the harborage points — the tight, warm, food-adjacent spaces roaches actually live in — and applying gel bait directly there rather than spraying open floor space. This targets the colony at its source and avoids the resistance issues that plague over-the-counter sprays. We follow up to verify the population has collapsed, not just scattered.
