The badgers' underground home is known as a "sett" and being clean, houseproud creatures, the badgers will frequently change their bedding. Our sett monitors regularly see balls of bedding left out to air, and occasionally we see badgers collecting bedding from the forest ground, and in a backward movement, drag the bedding back into their sett.  

The entrance hole to the sett could be described as a "Capital D on its side" and has to be the same width going deep into the tunnel.  If you kneel down and peer into the tunnel and it narrows considerably, then it's rabbits living there and not badgers.  The sides of the entrance hole may be polished as the badger's coat brushes against the sides.

Badgers are also prolific diggers and one sign of an active badger sett and in current use is the amount of spoil outside the entrance hole.  

Another tell tale sign of a badger sett in current use, is a furrow which the badgers make as they go in and out of their sett.  This furrow should be wide enough for the size of a badger.  Look very closely and you may see the distinctive pawprints of a badger in the spoil heap of furrow.
