Animal in the attic (possibly a raccoon)
We have just finished a major renovation of our house. Since complete, a possum has taken up residence in our roof. Unfortunately, it is living in the floor space between the ground and first floors and we have little or no access to this area. We have sprayed "Poss-off" in as many places as possible and cut all trees next to our house to reduce access but every night he comes back. I suspect that he is either walking along the power line (although it has a possum guard, I found possum scat under it) or climbing up the pipes to our pool's solar water system (50mm).
So the questions are:
what more can I do to discourage him
if we have it professionally removed (they are a protected species), will another one just take over.
