Cockroaches need three things to establish a colony: food, water, and warmth. Trilla's housing stock gives them exactly that. Housing spans historic river-town construction to newer suburban development near Springfield and the Metro East. Combined with Trilla's climate — a hot, humid summer climate with winters mild enough that snow cover is far less consistent than up north — indoor cockroach pressure rarely lets up on its own.
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.
