Plumbing walls that connect Whittier apartments
Census estimates show about 6,300 Whittier homes in buildings of five or more units and another 2,200 in two- to four-unit buildings. In many of these, kitchens and bathrooms are stacked or placed back to back, so the gaps around pipes under one sink lead into a wall shared with the neighbor.
German cockroaches use those pipe chases as highways. Spraying one unit often drives them next door and back again. A building-wide approach, where the manager lets us inspect and treat the connected units, is usually what ends the cycle. We can set up a plan for an entire building or work unit by unit with tenants.
