When it comes to rats, prevention really is better than cure, especially when the source of the problem is underground. One of the most effective ways to keep rats from entering your property is by fitting a Ratflap into your drainage system.
At ASW Pest Control, we’re often called to properties where rats have gained entry via damaged or unprotected drains. In these cases, rather than digging up pipework or relying solely on baiting, a Ratflap offers a long-term, preventative solution.
What Is a Ratflap?
A Ratflap is a stainless steel device that fits inside your drainage pipework and prevents rats from moving from the main sewer into your home or business. It allows wastewater to flow out as normal but blocks rodents from pushing their way upstream.
FAQ: How does a Ratflap work?
The Ratflap acts like a one-way valve. It allows water and waste to exit your property, but the flap shuts tight if a rat tries to enter from the sewer side. It’s simple, discreet, and highly effective.
Why Rats in Drains Are a Growing Problem
Rats are present in almost every urban and rural sewer system. While they may live comfortably underground, they’re constantly searching for access into properties, especially during colder months or when food becomes scarce.
If there’s damage to your underground pipes, or even just an unprotected entry point, rats can easily climb through and emerge inside kitchens, basements, utility rooms or cavity walls.
Signs you may have a rat problem from the drains include:
- Scratching or movement sounds near pipework or toilets
- Droppings or gnaw marks near floor-level entry points
- Unpleasant odours from drains or basements
- Rat holes near manholes or external drain covers
- Footprints or smears near service ducts or air bricks
FAQ: How do I know if rats are entering through the drains?
Common signs include regular sightings near toilets or drain covers, unexplained entry into basements, or finding droppings near soil pipes. A drain survey may be required to confirm the exact entry point.
Key Features of the Ratflap
- Full stainless steel construction — rust-resistant and built to last
- Fits both clay and plastic pipework
- Reversible flap — suitable for upstream or downstream installations
- Quick, non-invasive installation — no need to dig up pipework
- Suitable for domestic and commercial properties
FAQ: Can a Ratflap be fitted in any drain?
Ratflaps can be installed in most standard-sized pipework. Our team will assess your drainage system to ensure compatibility before fitting.
Ideal for Homes and Businesses
We recommend Ratflap installations for:
- Homes with recurring rat issues in kitchens, lofts, or basements
- Restaurants, takeaways, and food businesses with drainage access nearby
- Farms and rural buildings with open drain systems
- Commercial units with shared drainage networks or loading areas
- Any property undergoing pest-proofing works
FAQ: Do I still need pest control if I install a Ratflap?
A Ratflap is a powerful preventative tool but should be part of a broader pest management plan. If you already have an infestation, we’ll still carry out treatment alongside proofing to fully resolve the problem.
When to Act
If you’ve noticed signs of rats, indoors or out, and suspect they may be coming from the drains, don’t wait. The longer rats have access, the more damage they can cause.
We’re happy to inspect your site and provide advice on whether a Ratflap is the right fit, or if further drain-proofing or rodent control is required.
