The tennants from my IP are constantly complaining about possums at night within the roof/walls. I've paid nearly $1,000 now on professional pest inspectors to come in and fix the problem but the possum keeps comming back. My rental manager rang today to request to get the trees overhanging onto the roof trimmed back and i've approved this - might even get the trees choped down. If this doesn't work is there any other recommendations from the board to help get rid of the possum. The property is a highset workers cottage. Is there any chance that the possum is bypassing the trees and comming in from under the house, through the walls and into the roof.
