They can also leave behind the foul stench of urine and brown stains of secretion from their glands which they use to mark their territory.
If you can get into the roof you can put this nest box inside the roof and perhaps even place a bit of fruit in it.
Leave it in the roof for a few days for the possum to investigate and start putting its scent on.
