5 Common Pest Entry Points in Commercial Kitchens
By United Pest Editorial Team, Pest Management Specialist
For F&B operators in Singapore, keeping pests out of the kitchen is not just about hygiene — it's a legal requirement. Understanding where pests enter your commercial kitchen is the first step toward effective prevention.
1. Gaps Around Plumbing and Utility Pipes
Pipes that run through walls and floors create natural gaps that cockroaches, rodents, and other pests exploit. Even a gap as small as 6mm is enough for a young mouse to squeeze through.
Solution: Use steel wool combined with caulk to seal gaps around pipes. Inspect seals monthly.
2. Delivery and Back Door Areas
Back doors used for deliveries and waste disposal are frequently left open during busy service periods, creating an open invitation for pests.
Solution: Install air curtains or strip curtains at delivery entrances. Add door sweeps and self-closing mechanisms.
3. Floor Drains and Grease Traps
Floor drains connect directly to the drainage system, providing an underground highway for cockroaches and drain flies.
Solution: Install drain covers with fine mesh screens. Clean drains regularly to remove organic buildup.
4. Ventilation and Exhaust Systems
Kitchen exhaust hoods, ventilation ducts, and air conditioning units can serve as entry points if not properly screened.
Solution: Install fine mesh screens on all exterior vents. Schedule regular cleaning of exhaust hoods.
5. Cracks in Walls, Ceilings, and Floors
Structural cracks provide harbourage for cockroaches and entry points for ants.
Solution: Conduct regular inspections. Seal cracks with silicone caulk or cement.
