Katherine, Could be. Do the buildings feed into a common sanitary system? If the plumbing (or perhaps steam tunnels) connect the buildings, then I would think it is possible for the roaches to spread from a single source. Alternatively, an aging sanitary system might be fraying at multiple locations at once.
One thing I’d add to Richard’s post is after repairing the system, you should thoroughly clean the drains and perhaps have a professional apply an insecticidal foam product to kill roaches in the drains. --Dan Dan Wixted Pesticide Management Education Program (PMEP) Cornell University Ph (607) 255-7525 204 Rice Hall FAX (607) 255-3075 Ithaca, NY 14853 psep.cce.cornell.edu<http://psep.cce.cornell.edu/> [email protected]<mailto:[email protected]> From: [email protected] <[email protected]> On Behalf Of Katherine Fecteau Sent: Friday, June 28, 2019 3:11 PM To: [email protected] Subject: [pestlist] RE: Cockroaches Dear Richard and Dan, Thank you for your helpful feedback. I should clarify that I’m finding cockroaches in different buildings scattered across a multi-acre campus. Is my problem still likely plumbing related? Thanks again.

And if there are any steam tunnels on the property, these could be highways by which roaches spread from the source of the problem to other buildings. --Dan Dan Wixted Pesticide Management Education Program (PMEP) Cornell University Ph (607) 255-7525 204 Rice Hall FAX (607) 255-3075 Ithaca, NY 14853 psep.cce.cornell.edu<http://psep.cce.cornell.edu/> [email protected]<mailto:[email protected]> From: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> On Behalf Of Katherine Fecteau Sent: Friday, June 28, 2019 2:47 PM To: [email protected]<mailto:[email protected]> Subject: [pestlist] Cockroaches Good afternoon, I noticed a substantial uptick in the number of American and Oriental cockroaches caught in our blunder traps deployed in storage and exhibition spaces over the last two months and am wondering if this is part of a larger trend this year or if ours is an isolated case. 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.
