Joseph,
My experience with field mice and house mice is that once you have a
mouse invasion, you have a recurring mouse invasion problem. The little
varmints leave their scent (read pee) all along their path. This odour
marks the trail for the next mouse. Unless you block up the trail, mice
will continue to follow the path. Perhaps some odour blocker would work
but short of scrubbing with some strong cleaner I wouldn't bet on it.
BTW poisons are a bad idea. Other than the risk to pets who hunt mice,
if the mouse dies inside your vehicle walls/ducts, you have real
trouble.
On our '86 Syncro Westfalia, I found that the air intakes are not
properly covered with screening. If you remove the black plastic
headlight shroud you can get at this possible invasion point.
