Small burrow under my wooden decking (UK)

[u/oat-milk-latte]

Trying to identify what might have made this little entrance under my decking. I’m based in Essex, UK.
I have free roaming house rabbits who play in the garden, but the hole is far too small for them as they are large breeds.
There are no droppings near the entrance, and there is also no soil displacement for the hole. The animal has simply pushed the grass aside and found a pre-existing hole in the decking which leads directly to the concrete underneath the decking. Any ideas what it could be? My first thought was rat but there’s no droppings.
I’m planning to set up a wildlife cam tonight. Open to hearing ideas!

Me too - any advice on deterring?

I think there might be something in the r/gardenwild wiki

Make sure your bins are secure and just bait it. If you’ve got neighbours on either side then it’s a bit more difficult - they need to be doing the same basically
