We discovered this on Christmas eve. I had our house heat treated on 12-27. We kept seeing them and didn't find out it was the neighbors until February. I paid to have the apartments heat treated (landlord was MIA) and am now going after the landlord to get my money back. It is torture. We are still seeing them! Now we are tearing down drywall and sealing the brick wall underneath & replacing bedroom carpet with laminate flooring. I really would like to know how your situation worked out. Moving seems like a great option.

OP - OK, this is where I get to show my total ignorance of construction. There is quite a bit online, and a bit in this thread, about the risk of bed bugs moving between construction where buildings or units touch.

In older rowhouses (think 1880-1900), where there is a thick brick wall and foundation (or maybe it is a couple of walls that abut), would you under ordinary circumstances not suspect a problem? If not, maybe I can feel optimistic, do my own treatment, and expect resolution.

If it points to some kind of building repair issue I can have someone check, what am I looking for?

I think this advice is a bit overblown. The size of a hole that would allow a bedbug to crawl through is not at all an indicator that you have a fire safety issue. It’s not going to hurt to check it out, but bedbugs can get through just about any size space. And no home is really 100% sealed - otherwise you’d have no air left inside after a while... New homes are sometime so tightly sealed that they do require some sort of additional air circulation, but that doesn’t mean that an older home is a fire hazard just Because a bug can slip through from next-door

Says someone who has never read the fire code. What the OP describes sounds like a code nightmare, particularly the shared attic/ceiling space among units, soft/deteriorating brick party wall, etc. You need a one-hour fire-rated wall (minimum) with continuous fire-rated materials that extends 18" above the roof, ideally. You want no through-penetrations between the walls or units.

OK, quick disclaimer here: I am OP and I, confused and paranoid OP, doesn't understand the facts that well, which is part of the reason I am asking question. I assume there is some kind of gap because a neighbor once said there is. I have no idea of the claim is true. We probably have whatever is true of circa 1880-1900 rowhouses with flat roofs in cities like DC, Baltimore, and Philadelphia. Maybe we do have a continuous up to the bottom of the roof? Anyone know?

I do know the walls are continuous brick.

I can also say that walls are exposed in our basement, and are soft, and that when I showed this to a contractor and asked if we should address this, kinda shrugged, said it was possible, that the situation was common, and that no one bothers with it. But he did give me a ballpark quote for applying a mesh and coating to the expanse.

I strongly suggest certain amount of rodent tunneling between homes possible, unless this is an urban legend related to intrusion from the outside people misdiagnose. But I know someone who claims a rat just dug into the basement one day.

I'm in Baltimore, and people love to tell stories of that kind.

I might be insane. But in all seriousness, I figure we might as well look at everything carefully and at the very least if there things to foam , caulk or treat. Or inspect, if that's really a concern.

I really wish I understood the structure better, but I just don't.
