How many visits a year does your business need?

The rule: the pest's life cycle sets the schedule

Treatment does not kill eggs. If the gap between two visits is longer than the time eggs need to hatch and reach breeding age, you treat a fresh generation every time instead of breaking the cycle.

That is the whole calculation. Everything else is detail.

By activity

As a starting point before inspection:

• Central kitchen or high-volume restaurant — monthly, without exception
• Café or small restaurant — every one to two months
• Food warehouse — monthly, concentrated on goods-in
• Non-food warehouse — every two to three months
• Hotel or serviced apartments — monthly for common areas, on request for units
• School or nursery — monthly, scheduled around holidays
• Administrative office — quarterly
• Residential compound — every two months for common areas and drainage

When to raise the number temporarily

The schedule is not fixed forever. It is raised temporarily in three cases: at the start of an agreement on a site with an active infestation, through the summer months when cockroach activity accelerates, and after any construction or refurbishment that opens new voids.

Once things settle, it returns to its baseline. A good agreement allows for that rather than fixing one number for a whole year.

Why fewer visits cost more

A four-visit agreement for a central kitchen looks half the price of a monthly one. But it never breaks the cycle, infestation builds between visits, and you end up calling out emergency visits charged outside the agreement.

Do the arithmetic: four scheduled plus six emergency is ten visits at a higher total than twelve scheduled. And that is before counting what one cockroach in your dining room costs.
