Noticed a couple of holes appeared in the grass this week, about the
size of an empty toilet roll (2inch?) the first one I run the hose
down and it never filled ( A Chaplin sketch comes to mind lol) then I
placed a brick over it. The second I just put some old bricks, cement
down it. Next day the cement had been taken out!!

What could possibly be making them and why? I presume rats though
somewhat small maybe! Why no soil spoil either? If a mole needs to
make such big hills, how come this creature doesn't?

Not too fussed as I only cut my grass to make the lawn tidy, rather
than look like a cricket pitch. Just curious.

Could be bank vole. They are very good at making a whole 'rabbit
warren' of little tunnels in grassy areas, and they are very common.
The way the water was disappearing suggests the holes go a long way,
and the fact the cement disappeared suggests the hole is in regular
use, so I don't think it's squirrels burying nuts. Rats are very
sensible cautious creatures, and would prefer somewhere more out of the
way than a lawn which gets a lawn mower over it every couple of weeks or so.


2" is perhaps a bit big for a bank vole - they are usually around 1.5"
and there should be several of them scattered over quite a wide area.
Ours inhabit two areas down one side of the property and are frequently
visible when feeding on seed put out for ground feeding birds.

Aha see my previous post. I need to set up an observation post I
think. Do they come out in daytime too?
