LOL. Just out of interest, how did you think the crocus were going to get
through metal sheeting!?

Why not put some mouse traps down. Probably only a few doing the damage.

Have looked in the garden at first light this morning to find that more
crocus bulbs have been stolen :-((

Think I will try soaking briefly in paraffin (?) before planting again and
re-covering with bricks.

It takes weeks (months) for the bulbs to reach the surface, so no problem
with covering with solid heavy objects until shoots reach the surface.
The small predator(s) do not seem at all interested in digging out well
established and previous years' bulbs, it's only freshly planted bulbs that
get promptly removed.
