The reason Exchange Place needs a full-service exterminator is that a commercial district concentrates several different pest problems in the same buildings, and each one is a business risk rather than a household nuisance. German cockroaches are the headline pest of the ground-floor restaurants and the Harborside food court — high-volume food service gives them the warmth, moisture, and equipment voids they need, and they move between adjacent tenant spaces through shared plumbing and chases, so a cockroach in a food court is a health-code problem, not a countertop one. Norway rats and house mice work the service corridors, loading docks, and basement utility chases that knit the towers together, drawn by the waste streams of a district that feeds thousands of workers a day, and a mouse on a trading floor is a reputation problem.
Above the units, the building envelope generates the rest. Pigeons and other rooftop birds foul the corporate tower ledges, cornices, signage, and HVAC equipment — a liability and sanitation concern on high-visibility waterfront buildings, not just an eyesore. The modern slab-on-grade and steel construction keeps subterranean termite risk near zero, reducing what dominates older brownstone districts to occasional inspection of the older mid-rise mixed-use buildings, and bed bug pressure is low, surfacing mostly in the occasional residential or hospitality tenant. Brown marmorated stink bugs are the seasonal exception, clustering heavily on the south- and west-facing tower curtain walls every October and slipping in through any gap.
