if you do he'll eat it and end up back where he is nesting and die there. Use mouse traps, leave two up front and one in back (take some pics of the catch) leave windows and Ttops off, take you seats out if you haven't yet. With a vaccum suck all the insulation out and wipe the entire interior with bleach and the with ammonia, but don't use both at the same time. For a few days after spray some odor eater, something with out perfume. It happened to a friends 240Z eventually he got rid of the smell. Good luck
