I just caught 2 mice in my parents house.I used a standard mouse trap
baited with peanut butter. I could hear them running around in the
ceiling.Their little toe naiils going pitter patter against the ceiling
boards.Cute little things ,they are.

I placed one trap up there by moving a ceiling tile. SNAP!! Within 5
minutes I got a mouse.Next day, I placed the trap up there again.BINGO!!
within 5 minutesI got his friend. I suppose they had a fight over who got
the bait,first time.

Just put a trap baited with peanut butter in your Vanagon.If you dont eat
in your Vanagon,the peanut butter will get him before you can go back into
the house. Lots of crums in most cars, but that peanut butter is so
smelly ,it will overpower his good sence.

Why go high tech  for a better mosse trap than this?
