The problem

Rats thrive alongside humans and use drains to travel un-noticed as they search out warmth and food in homes and buildings.  They most commonly enter buildings through the drains.  Rats pose a health risk and cause damage to property including being a fire risk as they chew electrical cables.

At Emerald Pest Control we have used other rat valves in the past but we know only use Ratwall. We have been extremely impressed with the customer service but more importantly the valve is easy to fit, robust and well built. We would never use any other product.


Perry Wright, Emerald Pest Control

Superior quality build, simple to install, with the bonus of the installation pole if needed, the Ratwall works as good as it looks. Great support when needed from the team at Metex. Would recommend as the go to non-return valve for serious pest controllers.


After a lot of research and trial and error thankfully we found the 'Nordisk TX11' double flap rat blocker! It is a robust product that was easy to fit and has solved our rat issue! The fitting mechanism is far superior to any of the other products we tried. Thank you to Metex!

We have been fitting Ratwalls now for a while and in my opinion they are a good solid product. Installation is usually straightforward and they do have design advantages over other similar products. In addition to this we have also found them to be in a satisfactory condition during servicing after periods of normal use, which is reassuring. In fact it’s now our most sold rat prevention item and our first choice to fit.


Mick Grant ACIPHE RP, MG Drainage Ltd

After months of searching for the rat entry point, this was found to be an old drainage pipe which had never been sealed off, we fitted one ratwall device which was so easy and have had no problems since.


Mr M Brooke, Sittingbourne, Kent

We have been fitting rodent exclusion devices for over 10 years now, and I can happily say Ratwall is the sturdiest and best designed rat exclusion device we have fitted and we have installed them all!.. I am delighted with its performance to date and unlike other devices, we haven’t had a single complaint or failure since we started fitting them, often in the toughest conditions. If installed correctly this device will resolve rat infestations in any property caused by drainage defects, simply and cost effectively…..Job done!


So far...so good! I don’t want to jinx it, but I haven’t had any foul smells or heard that anxiety provoking scuffle from the loft at night since installing the Rat Blocker. Long may it continue! Fingers crossed!


Tess, Brighton, East Sussex

We’re happy fitting Ratwall and have used other rat valves in the past... they are more competitive and this product is robust and well made. It’s easy to fit with its compressible side walls and stays secure when installed. The Metex guys are efficient and simple to deal with.


Scott Hyslop, General Manager, Pest UK

We have now purchased several Ratwall valves and have been so pleased with the ease of installation and quality of the product that we have replaced valves from other company’s which have been chewed through. Since installation our clients have reported back that there infestation of rats/vermin has stopped and they can sleep with ease once more. I’d highly recommend this product to anyone with a rat/vermin issue that results from their drainage chamber.


Ian Robinson, Drain Doctor, Central London

Someone recommended Ratwall and I can honestly say after living with this problem for nearly two years it has completely disappeared with the installation of this device. Highly recommend!


Liz, Hampshire

Arrest Apest recommend using Metex Ratwall Rat Blockers, we have fitted lots of these ourselves and they have fitted perfectly every time, high quality product and we wouldn’t use any other make. These come highly recommended.


Paul Tittensor, Arrest Apest

I came across Rat Wall which was delivered and fitted within a couple of days. I wasn’t expecting it to stop the problem but here we are 1 year later and not a single rat or problem with my drain, couldn’t be happier with our purchase.


Wayne Morley, Medway, Kent

Ratwall was easily installed into the drain, this was approximately 18 months ago and we have had no call back from the customer as to the rat infestation that she was experiencing at the time. The service from Ratwall was quick and efficient.


Olivia Cordery, Active Drainage Ltd

We highly recommend Ratwall. A brilliant product, as described, easy to fit and definitely works!
