Hi Nfcb,
can you remember if the mice were taking the food late summer Autumn. As I have a theory, and it is this. Obviously it was observed by a camera that you had access to so it was actually seen.
But my theory is this, the mice were taking away the food to store for the winter months when food would be scarce. But what the answer would be to combat that, is probably that there is not one. Mice can get into real small places. Even if you humanely trap the mice and let them go a couple of miles away, others would probably fill the vacuum. No easy solution.
Willpar.
