There may be a dry floor drain under some cabinetry. Heavy rains tend to

Katherine,
Are you certain these are American and Oriental cockroaches, and not wood
roaches? If they are what you say, then I'd wager a considerable sum that
they're simply marching up from the sanitary system. As Dan mentioned, if there
are utility tunnels connecting the buildings, then those

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

aging sanitary system might be fraying at multiple loca

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

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 curio
