unwanted intruders

i think we have some unwanted intruders in the shed.

  A pile of grain leaking from one of the sacks.

And moving the pile there is  a whole lot more.

So 2 problems.

How to clear up the mess.

That is easy. Just let in the hoover-uppers

 And viola

And the holes in the sacks are small so I think its mice that have been at the sacks .
