Rats are in almost every sewer

Do you have 50 to 60 mm holes in your soil that reappear soon after you fill them in? Or where rats have gained entry to your building, you hear noises on a regular basis but cannot locate their entry hole.

The last thing you want to do is to lay poison as they may die in your wall or attic space and decay causing a horrific smell and fly problems.

Installing the RATFLAP® will allow any rat to leave your property as normal but stops the rats in their tracks from returning, thus solving your elusive rat problem. The Ratflap® is an environmentally friendly solution to your rat problem as it does not kill or maim the rat.

We all have rat problems

Rats inhabiting your house is undesirable for most people and up until now stopping the rats at street level has proved impossible because of the need for efficient waste flow inside the pipes.

Having spent 12 years in the pest control industry we are aware or the huge problems that badly constructed and damaged sewer pipe systems cause to homes and places of work with regard to rat infestations. When the problem was identified in the sewer then it had to be fixed usually by digging up the offending pipe and replacing it a huge cost. Installing a Ratflap® stops all the sewer rat problems forever.
