Cockroaches need three things to establish a colony: food, water, and warmth. Andale's housing stock gives them exactly that. Ranch-style homes and newer suburban construction dominate, nearly all built with basements given the area's severe weather risk. Combined with Andale's climate — a climate defined by both summer heat and winter cold, with spring storm season a defining feature — 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.
