1. Make or buy a suitable nest box for the Common Brushtail possum, and install it in your garden to act as an alternate den site for our furry friends. For more info on nest boxes, check out www.baag.com.au for more info.

2. Locate the nest the possum has built in your roof, remove it (when the possum is out and foraging) and place this inside the nest box. This will encourage the possum to move to its new location.

3. Place a piece of fruit inside the nest box. Apple or bananas seem to work best. This will entice the possum to investigate the nest box, and hopefully decide to stay. It should be stressed that feeding of possums is not recommended (except as a one off during relocation).

4. Block of access to your roof. This can be done by loping any overhanging branches, and placing collars around the trunks of trees that possums utilise to access the roof. Collars can be made from a number of products, but 60cm wide sheet iron seems to work pretty well.

5. Place camphor blocks OR mothballs in the roof space, particularly around the area where the nest site was. DON"T place both! Possums really dislike these smells, and will be reluctant to return.

6. If possible, pop a light up in the roof space, and leave it there for a few days (on of course!). The combination of alternate nesting site, bad smells and light should be sufficient to discourage them.

7. Once you are satisfied that the possum has left the building, block any known entrance points. Wiping around the entrance points with household bleach will remove possum scent, and make re-entry pretty unappealing!
