Thanks for all advice, David.

When you say dig beneath smaller hills, are you still referring to a
pile of excavated earth - or just an area of grass that appears to have
been pushed upwards?

If you are referring to the smallest hills, am I right in thinking the
first thing you do is carefully lift off, and gently brush away, the
soil . . . leaving you with just the grass beneath?

Then if that's right, do you just start gently digging in the middle of
the exposed area? What I mean is, these creatures are tiny, so their
tunnels must be narow, so the tunnel could be anywhere in the circle of
grass underneath the mole-hill. Do you just lift off the entire
"disc", so to speak?
