Would you believe I found mouse droppings in our minivan!!!! I came home from school drop off and had to dismantle the van, taking the seats out etc to give it a complete clean and vacuum.  Then it was off to Home Depot to buy a kid proof mouse trap to put into it.  What a nightmare.  Can't figure out how it got in but it was certainly feasting on all the dropped kids snacks.   Now I'm scared to drive it in case it runs up my leg while my feet are on the pedals (shivers).

Lesson learned - no snacks in minivan and check kids are closing the doors properly.
