We still have not completed work on renovating our garden because we have at least one squirrel who has taken up residence.
I could not move the tape further in. Not sure if the tunnel goes down or makes an abrupt turn. And the tape did not bump into the squirrel.
The squirrel may not be using this hole. I suspect that the two holes are connected by an underground tunnel.
We attempted making a bird feeder that would prevent the squirrel access.
