Had a mouse, where else this insulation/deadener?

[PNWPMM86]

Mouse is dead, but after cleaning up the mess it made nesting in my trunk, cabin filter, back seat and ontop the engine (snow made it sit for several weeks without use, this happened on the last cold snap, only took what must have been a day and a half), I need to find out where else to look for this material to replace or clean up. See attached photo. This is from the right front passenger side panel on the dash that the door closes onto.

Wiring looks good so far.

Huh? What is the question - where is there sound deadening? Its all through the car. Dash panel inside and out,trunk, etc. Depends which model too.
