Anyone else use this stuff? I've had the little f*****rs fill up my entire air filter box, packed the area under the intake on my Powerstroke with insulation, leaves and whatever. It took me 2 hours to vacuum it out. They even got in my heater so it smelled like mouse turds and devil snot. Not anymore. I've been jamming sheets around wires and wherever in the engine compartment, throwing a bunch of sheets in the cab for 4-5 years. It works! That time of year.
