What kind of critter?
Back of the yard, near the common ground (where there are a lot of scrub-type bushes) there is a tunneling problem in the yard. Every few inches, there are holes where you can see down into the tunnel.
What kind of critter does this? Neither Dh nor I have seen any animals, but something is making these tunnels. We have no idea what steps to take next unless we know what the critter is...
