I have been told that possums are not likely to chew wiring. Rats, on the other hand, are much more of a problem. We also have rats in our ceiling. It is a real menagerie up there
. We have had rats chew through a wire already in our ceiling, so we know they are a danger regarding fires.
About a fortnight ago, we had our pest chap put baits in the ceiling for the rats in little boxes that he says the possums cannot get into. We don't want to harm the possums.
I would be interested to know whether possums do, in fact, bother chewing wiring. He said not likely, but I am curious to hear the opinions of anyone who has experience in this regard.
I am not keen to ban the possums but, of course, the safety of our family must come first. It is just that as far as I know possums are not likely to chew wiring.
