Rats entering your property through the drains is more common than you might think. If you’re hearing scratching in the walls, noticing droppings, or experiencing unexplained foul smells, you may have rodents coming up through your drainage system. At Milton Keynes Pest Controllers, we provide professional installation of drain rat blockers and stoppers in Buckinghamshire, helping homeowners and businesses stop rats at the source — before they become a bigger problem.

Why Do Rats Use Drains to Enter Your Property?

Rats are opportunistic and clever. The underground drainage system offers them a direct route into kitchens, bathrooms, basements, and even cavity walls. If there’s a broken pipe, missing interceptor trap, or open access point, rats will exploit it.

Common signs rats are using your drains include:

• Noises under floorboards or in walls

• Rat droppings in basements or utility rooms

• Gnawed pipes or cables

• A strong ammonia-like odour

• Sudden infestations without exterior entry points

2. Blocker Selection: We choose the correct size and type of blocker for your system.

3. Installation: We professionally install the rat stopper in the appropriate chamber.

FAQs – Drain Rat Blockers & Stoppers in Buckinghamshire

What is a drain rat blocker?

A drain rat blocker is a stainless steel or PVC one-way valve that fits inside your drain or sewer pipe. It allows water and waste to flow out of your property but blocks rats from getting in through the same route.

How do rats get into properties through drains?

Rats use broken pipes, open access points, or damaged sewer connections to travel through drainage systems. They can climb vertically and squeeze through small gaps, entering properties via toilets, utility rooms, or kitchen waste pipes.

Do drain rat blockers affect water flow or drainage?

No. A properly installed rat blocker allows full flow of water and waste out of the system. The one-way mechanism ensures rats can’t come back up through the drain but does not block outbound flow.

Can I install a rat blocker myself?

We recommend professional installation. Installing the wrong size or placing it incorrectly can cause drainage issues or leave gaps for rats to bypass. At Milton Keynes Pest Controllers, we ensure a secure, proper fit for long-term protection.

Will a rat blocker stop all rats from entering my home?

Drain rat blockers prevent rats from entering via the drainage system. If rats are still gaining access, they may be entering through gaps in brickwork, vents, or rooflines. We offer full property inspections and advice to seal all potential entry points.

How long does a rat blocker last?

High-quality stainless steel rat blockers can last many years with little to no maintenance. They’re built to withstand harsh drain conditions and regular water flow.

Do you offer drain surveys before installing a rat blocker?

Yes. We can carry out a CCTV drain inspection if needed to identify where rats are entering and confirm the best place to install the blocker. This ensures effective prevention.
