I have a 98 e320 and while cleaning leaves around the hood at a gas station I noticed a mouse has taken up residency behind the engine wall. Saw it skurry into hiding. Sort of between where the rain would run off the windshield and flow through to the ground and the master cylinder. I can't reach in there very well so...

To extracate the critter I was wondering if I could just blast the garden hose back there with abandon or if another method is advised?

Thanks.
