A food business generates more pest pressure in a week than most homes do in a year. The service interval that keeps a house quiet is rarely enough for a kitchen.
Restaurants combine everything pests are looking for in one building: constant food residue, warm equipment running around the clock, standing water in floor drains and under dish stations, and a steady stream of deliveries arriving on cardboard. A home has one or two of those. A kitchen has all of them at once, every day.
Monthly service is the common baseline for a restaurant, with higher-risk operations moving to every two weeks. It is not an arbitrary number — it tracks the reproductive cycle of the pests that matter most in kitchens. German cockroaches in particular can rebuild a population between widely spaced visits, so a schedule that lets two months pass tends to produce a cycle of flare-ups rather than steady control.
A newer building, a well-sealed exterior, disciplined nightly cleaning, sealed dry storage, and a history of clean inspections all reduce pressure. Even then, most operators stay on a recurring schedule rather than dropping to on-call — the point of the program is that problems get caught before a customer catches them.
A monthly visit that repeats the same spray in the same three spots is not a program. What makes the interval work is that each visit includes monitoring devices checked and replaced, entry points reviewed, moisture and sanitation issues flagged back to the manager, and treatment adjusted to what the monitors are actually showing. That record is also what you hand an inspector.
Health inspectors generally want to see evidence of an ongoing relationship with a licensed provider: service dates, what was found, what was treated, and what corrective actions were recommended. A binder that shows twelve months of consistent visits answers a very different question than a single invoice from the week before the inspection.
The right interval depends on your building, your volume, and what your monitors show in the first few months — not on a generic rule. We set the starting schedule after walking the kitchen, storage, and exterior, then adjust it based on what the program actually finds.
