On returning to my narrowboat after a few weeks break I found small black (6-8mm) round ended droppings near to and inside my log box which is situated inside the boat, newspaper had been shredded but strangest of all the wooden balls to a solitaire game have disappeared. One window is left open during winter to keep the boat aired, there is a mooring rope from the ground to the top of the boat situated next to the window. The boat is moored on a canal in Shropshire on farmland, there are burrows on the canalbank side ,underneath a paving slab. Is it possible to identify this visitor to my boat ?
Definitely the smaller droppings, would a mouse be able to carry small wooden marbles and what do you think they would do with them, I find it intriguing that they would take a whole games worth.
I work in pest control and you can always tell what type of mouse is in a house by what you find around the mices nests. House mice don't tend to collect things, wheras field mice do. You find all sorts of odd articles in their nests and on their food sources (or my bait trays). The articles include wood chips, wood shavings, twigs, ring pulls, bits of plastic etc. I think there placed there as territorial markers to other field mice. I would expect it would include wood marbles. Also they chew items to keep their growing from the base teeth short.
It sounds odd but it could be a case of nautical field mice? Set some break back traps and you'll soon see what type of mouse it is. Peanut butter is the best bait.
