The expanding foam will do very little once the rats have a run they will go through it as they rely on set routes.
I'm also sceptical as to whether the led trick will make any difference, rats do go out in daylight.

Expanding foam does not work, rats can chew through it very easily , you need to use something more solid like concrete

Concrete mixed with smashed glass is best as it cuts them as they try and chew it
