Katherine, Your observations suggest that there are breached waste lines (or vents serving those systems) in these spaces. They may be ancient abandoned pipes hidden in walls, above ceilings or even beneath floors. There may also be a drain that has gone dry and is unknown to you and your associates. We have these 'eureka!' moments all the time, and I frequently hear folks who've been in a building for decades utter 'I never knew that there was a drain hidden there'. Even the building managers may not know what old systems hide behind plaster walls.
These cockroaches will, indeed, wander about further afield within a building, but they'll be most numerous near the 'off ramp' they use from their little Mass Pike of the sanitary system. Feel free to reach out directly next week to discuss means to discover the source(s). Once those are located, repairing the systems will return you to your regularly scheduled programming.

I’m curious because we’re finding these cockroaches in spaces that are nowhere near drains or plumbing. Are they responding to the humid conditions we’ve been experiencing in western Massachusetts over the last few months, or is there perhaps a larger issue we’re dealing with? Thanks for your time and input.
