Check first to see if floor drain traps have evaporated and are now dry....if 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. Joel Voron Colonial Williamsburg Foundation Conservation Dept.

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.
