Rats thrive alongside humans and seek warmth, food, and build nests within buildings. They use drains to travel un-noticed into the buildings and also use more obvious entry points such as cracks in the walls. Rats pose a health risk and cause damage to property including being a fire risk as they chew electrical cables. To proof a building against rodent entry all entry points must be considered and addressed. Blocking obvious entry points such as visible cracks is relatively straight forward, however drains are actually the most common entry point.


Metex provide high quality, effective rodent proofing systems for homes and buildings. Metex can offer a choice of products to stop rats accessing a building through the drains as well as a robust proofing tape to cover building defects. Rat blockers are available in a range of sizes to suit both domestic and industrial use.


All Metex proofing products are non-toxic. The Rat Blockers effectively stop rats and other rodents passing through drains towards a building whilst allowing them to pass freely downstream. A Metex Rat Blocker allows the drain to function as normal. By installing a Metex Rat Blocker into the drain outlet all upstream branches are protected. Metex RatTape can be rapidly applied to block a rodent entry point in the building fabric.

Pest Control FAQs

+ Help, I have rats in my house, where do I start?

Rats can enter house in a number of different ways and the pest way of permanently eliminating them is to employ a professional pest controller to survey the property and implement measures to eliminate the infestation and prevent it re-occuring. It is possible to take measures on a DIY basis, but there is danger that the time taken to elimination will be extended.

+ How do rats enter a building?

Rats use drains as a hidden highway to access buildings, as they push upstream seeking warmth, food and nesting sites they enter buildings. Rats can travel through pipes directly to the back of a toilet where they often chew the flexible toilet pan connector, causing upset and damage.

Absolutely. If there is a defective drain rat will often use this to gain access to a house.
