Hong KongPest control: three questions, and how to get all three
Three of the eighty questions, the smallest area on the exam. All three come from one sub-area: implementing pest control prevention. Deny access, deny food water and shelter, and work through a licensed pest control operator.
Three questions. Less than a twentieth of the paper, and a fifth of what contamination is worth.
Spend twenty minutes here and move on. What follows is most of what those twenty minutes should contain.
The three-part strategy
- Deny access. Screens at 16 mesh to 2.5 cm (1 inch), self-closing doors, sealed gaps around pipes, air curtains. Pests arrive in deliveries as often as through doors, which is why receiving inspection is also pest control.
- Deny food, water and shelter. Food off the floor, spills cleaned, waste covered and removed, standing water eliminated, cardboard broken down rather than stacked in a corner.
- Work with a licensed pest control operator. Not a manager with a supermarket spray.
That third point is where most of the marks are. Pesticides in a food establishment are applied by a licensed operator, stored away from food, and used according to the label. A manager buying something and spraying the dry store is the wrong answer in every question it appears in.
Signs, by pest
| Pest | What you find |
|---|---|
| Cockroaches | A strong oily odor, egg cases, droppings like coarse pepper, and daytime sightings meaning a large population |
| Rodents | Droppings, gnaw marks, greasy rub marks along walls, nesting material, holes |
| Flies | Adults near waste and drains, and breeding sites in drains rather than in the open |
Daytime cockroach activity is the detail worth carrying into the exam. They are nocturnal, so seeing them in daylight means the harbourage is full.
The correct response is to contact the pest control operator and identify how they got in. Cleaning up the droppings and carrying on treats the symptom, and that option is always on offer.
Integrated pest management
The formal name for the same idea: prevention first, monitoring continuously, chemicals last and by a professional. If a question offers a preventive answer and a chemical answer, the preventive one is usually right.
Where pest questions hide
This area overlaps two others. Outer openings and screens sit in facility design. Cardboard and waste handling sit in contamination. A question about a propped-open back door could be scored in any of the three, which does not change the answer but does mean the topic is worth slightly more attention than three questions suggests.
One more thing that appears occasionally: a severe infestation is an imminent health hazard. The response is the same as for a sewage backup - cease operations, notify the regulatory authority.
Common questions
How many pest control questions are on the food manager exam?
Three of eighty, the smallest content area. All three come from the same sub-area, implementing pest control prevention, so the material is narrow and worth a short focused session rather than a long one.
Can a manager apply pesticides in a kitchen?
No. Pesticides in a food establishment are applied by a licensed pest control operator, stored away from food, and used per the label. A manager spraying a supermarket product is a wrong answer wherever it appears.
What are the signs of a cockroach infestation?
A strong oily odor, egg cases, droppings resembling coarse pepper, and sightings during the day. Cockroaches are nocturnal, so daytime activity indicates the harbourage is already full.
What should you do when you find pest evidence?
Contact the pest control operator and work out how they got in. Cleaning up the evidence and continuing is the option the exam offers to see whether you treat the symptom or the cause.
What mesh size do window screens need?
Sixteen mesh to 2.5 cm (1 inch). Screens, self-closing doors and sealed gaps around pipework are the access-denial layer, and they also appear under facility design.
