thanks for the pointer Tony

rather "mop closet drain" then

"Make sure there's no forms of still water or moist food anywhere in the kitchen that they have access to.
Here's a quick list of things, but the main point is to make sure things are clean and dry:
All sinks need to be scrubbed and dried, including the drain
Floors need to be dry, including any areas covered by equipment (this means checking underneath the fridge, counters, and whatever)
Check your sink's air gap
Your garbage cans need to be cleaned and dried and make sure no one throws any type of wet food in them
Check all drains like the floor drain and mop closet drain"
