Possums can be really crafty, and sometimes quite dangerous creatures. However, they are non-confrontational animals. While they are not likely to bite they are more likely to show their sharp teeth, growl, or hiss.
They do get more dangerous when they are backed into a corner, so there is no need to aggravate them. They are a relatively placid animal and like to avoid confrontation at all costs. However, if trapped they will resort to their ability to bite.
Fortunately, possums rarely carry the rabies virus due to their low body temperature. Nevertheless, precaution must still be taken as their bite can cause an infection around the bite site that won’t go away when left untreated. Help from a medical professional and some antibiotics will generally clear up the problem.
On top of this, possums are Australian native animals and are protected by law. Their removal can only be carried out by someone who holds a Damage Mitigation Permit. So you should call in the professionals – this is where King Arthur can help.
