The most effective mouse traps will kill, and no worries about mouse dragging trap. You need to buy traps at the hardware store, the plastic trip ones will work fine- victor- and you don't even need to bait them, though a lil dab of PB will enhance your chances. The glue trays are also good, just place them throughout vehicle until you get the mice. Most likely more than one, and only way to eliminate them, is to eliminate them. good luck
