Are there sewer pits in the building?  They can come in on the underside of a 
pallet and settle in sewer pits quite easily as well.

Dear List -

My head of security has come to us with an issue.  Apparently, they are being 
overrun with giant cockroaches (water bugs) in the basement and apparently it 
is starting to creep up to the first floor.  There is no construction going on, 
and the café kitchen has apparently never been cleaner.  Thoughts as to what a 
sudden influx of these pests might be indicating?  Thanks in advance.

 Check first to see if floor drain traps have evaporated and are now 
dryif so just fill them with water. This happens when the drains are not 
used on a regular basis.


  Someone down the line could have been doing work on the sewer lines and 
drove them up to your site as well.

[Pollack, Richard J]

Lisa,

Assuming these are American cockroaches, they're likely from the sanitary 
drains. Check all floor drains to ensure the traps are hydrated. If you're 
lucky, you just need to have those topped off periodically. Then, check other 
drains. In some cases, you may need to have the sanitary lines and vent stack 
checked for integrity.
Good luck.
-Rich
