Dry storage and deliveries
Check incoming deliveries before they go into stores, keep dry goods in sealed containers, and use stock in rotation so nothing sits at the back of a shelf for months.
Drainage and floor edges
Floor drains, grease traps and the edges behind fixed equipment stay damp and undisturbed — exactly the conditions that sustain cockroach activity. Build them into the cleaning schedule.
Waste and closing routines
Empty bins before close, move waste containers away from kitchen walls, and finish with a wipe-down of preparation surfaces. A consistent closing routine is the most effective single measure.
