German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Fort Garland's a high-elevation alpine climate with heavy winter snowfall and short, cool summers, far colder than the Front Range keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Mountain-style construction is the norm here, designed around the region's heavy and long-lasting snowpack.
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.
