Designed by a pest controller who understands the biology and behaviour of brown rats, the RATFLAP® is designed to stop rats in their tracks, while not affecting the flow of the sewer. Made entirely from 304 grade stainless steel and precision cut by laser meaning RATFLAP® will last for decades. Taking years of development the device is designed to be a simple "fit & forget" solution and can be fitted by almost anyone although a basic knowledge of sewer flow and layout is recommended.
