Employees bringing small appliances/furniture from homes or thrift stores is usually how German cockroaches get into a workplace. Best to have that prohibited in policy. Of course cardboard can be a vector/issue as well. A small leak under a sink can create the perfect microclimate under a cabinet for a nest of German roaches. They also like the warmth of electronics especially if the are left on overnight. A rotation of professional baiting with a non repellant spray (in non exhibit spaces) is the best way to eradicate. German roaches are really good at developing pesticide resistance. JTV

Do not click links, open attachments or take action unless you know the contents are safe] Hello, in Peru we tend to associate small German cockroaches with kitchens (especially restaurant kitchens) - mostly due to kitchen grease and animal fat leftovers or remains of fried foods. Our American cockroaches are more sewer and garden related. Is there any chance you have old cooking exhaust pipes nearby with leftover grease or a nearby restaurant kitchen?

They may occasionally accumulate around a drain for moisture, but they wouldn’t arise from the sewer lines below.
