Pests in a workplace are more than a nuisance. Cockroaches and rodents can contaminate food and surfaces, cockroach droppings and shed skins can trigger allergies and asthma, and rodents gnaw through cables and packaging. A single sighting in front of a client can also do real damage to how your business is seen.
The good news is that most workplace infestations are preventable. Pests come in for three things: food, water and shelter. Take those away and the premises become far less attractive.
Common workplace pests in Singapore
- Cockroaches: the smaller German cockroach tends to live indoors around pantries, appliances and cabinets. The larger American cockroach often comes up through drains, pipes and service risers.
- Ants: follow food trails into pantries, desks and bins.
- Rodents: move along walls, ceilings and cable trays, especially near food outlets and rubbish areas.
- Mosquitoes: Aedes mosquitoes, which spread dengue, breed in small amounts of standing water indoors and out.
Close off the entry points
Pests get in through gaps that are easy to overlook: around pipes under the pantry sink, cable openings, gaps under doors, damaged ceiling boards and drain covers.
- Walk the premises with a torch and check under sinks, behind appliances and around service openings.
- Seal small gaps around pipes and cables with a suitable sealant.
- Fit door sweeps on doors that lead to corridors, loading areas or back-of-house spaces.
- Keep drain covers and floor trap covers in place.
- Report gaps in shared areas, risers and ceilings to building management, as these are usually outside the tenant’s control.
Clean the pantry and remove water
A pantry that looks tidy can still feed pests. Crumbs under the microwave, grease behind the fridge and sticky residue in cabinet hinges are enough.
- Wipe counters and sinks at the end of every day.
- Clean under and behind appliances regularly, not only the visible surfaces.
- Store snacks, sugar, coffee and biscuits in sealed containers.
- Do not leave dirty cups or dishes in the sink overnight.
- Fix dripping taps and leaks, and empty dish-rack trays.
Standing water matters for dengue as well as cockroaches. Empty water from plant saucers and vases at least weekly, turn pails upside down after use and keep condensation trays dry. NEA can take action against premises found breeding mosquitoes.
Manage waste and bins
Rubbish is food and shelter in one place.
- Use bins with tight-fitting lids and liners.
- Empty food waste every day, including from meeting rooms.
- Do not leave rubbish bags in corridors or back doors overnight.
- Rinse food containers and drink cans before recycling.
- Clean the bins themselves every week. Residue at the bottom attracts cockroaches and flies.
Train staff and record sightings
Staff see pest activity long before a pest control technician visits. Make it easy for them to report it.
Tell staff what to look for: live or dead insects, droppings that look like black pepper or coffee grounds, egg cases, gnaw marks and ant trails. Ask them to report each sighting with:
- the date and time;
- the exact location;
- what they saw;
- a photo, if possible.
A simple log helps a technician find where pests are hiding and judge whether treatment is working. Our free pest-sighting log template is written for food premises, but the same fields work in an office pantry. Ask staff not to spray household insecticide over areas where a technician has placed bait, as sprays can make baits less effective and push cockroaches into new hiding places.
Work with a registered operator
Prevention reduces the risk, but it does not remove every pest that is already established. Regular inspection by a professional catches early activity before it becomes an infestation.
In Singapore, pest control companies must be registered with NEA as Vector Control Operators (VCOs). When you choose a provider, check the registration and ask:
- What will be inspected on each visit?
- Which treatment methods will be used, and what precautions do staff need to take?
- Can visits be scheduled after hours to avoid disruption?
- Will you receive a written service report after each visit?
KleanSG is an NEA-registered Vector Control Operator (VCO20220007). Our pest control services page lists what we cover. Restaurants, cafes and other food premises should look at F&B pest control. Preschools, schools, specified shopping malls and other premises under NEA’s Environmental Sanitation Regime may also need a comprehensive pest management survey.
