Get rid of rats by knowing how they get in
Identifying the cause of the rat issue is not something most people can see without a drain camera and a knowledge of rats and drainage in general. It is very easy to draw the wrong conclusion of the source of the rat infestation when looking around the building or above ground.
In addition it takes much more than a drain camera and an understanding of drainage – you need to understand rat ecology and rat capability as well as building construction and architectural history before you have the fully rounded intel required to crack these rat infestation scenarios.
That’s why drainage contractors and construction contractors usually fail at getting rid of rats.
