German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Newborn's a humid subtropical climate with hot, humid summers and mild winters, typical of the Piedmont, cooler in the mountains to the north keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Crawl-space and slab construction is common here, built for the region's humid climate rather than deep winter cold.
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.
