Revolutionary New
Drain Protection
Rats, cockroaches and sewer gas don’t need an invitation, just an open pipe. PestFlap is a one-way mechanical valve that retrofits into your existing drain in minutes and stays sealed until wastewater needs to pass through. No power, no chemicals and no unnecessary complications.
Where It’s Used
Wherever a Drain Is a Liability, PestFlap Is the Fix
Healthcare
Infection control and pest-free compliance in high-scrutiny environments.
Industrial
Protecting stock, machinery and staff welfare areas from pest ingress.
Restaurants
Passing health inspections without citations related to drain access.
Education
Maintaining clean, pest-free environments across washrooms, kitchens and shared facilities
Hotels
Protecting guest-facing spaces where a single bad review about a bug in the bathroom can cost far more than the fix.
Residential
Peace of mind for homeowners who’ve had a rat in the toilet or want to prevent one from getting there.
Pest Control Can’t Treat
What It Can’t See
You can spray, bait and seal every entry point above ground and still have pests return because the route was never above ground. Sewer lines, floor drains and toilet connections can provide direct access into a building, and these routes are often left unprotected. An exterminator can clear an infestation, but they cannot prevent pests from returning through the same drainage route. That’s the gap PestFlap is designed to close.
Choose the Right PestFlap for Your Drain

How PestFlap Works
One Valve. Sealed by Default. Opens Only When Needed.
PestFlap sits inside your existing drain and does one job without any electrical components to wear out because there aren’t any. It’s purely mechanical.
Blocks:
Sewer gas from rising into the room
Rats and cockroaches from climbing up through the pipe
Foul odour from escaping the drainage system
Backflow, splash and aerosol particles from passing back through
Allows:
Full drainage flow during normal use, nothing is restricted
Standard cleaning and maintenance access
PestFlap allows water from mopping or spills to drain away as normal.
PestFlap allows standard drain servicing without needing to remove the unit.
