Possums
In New Zealand there are no predators and lots of very palatable vegetation. As a result, possums have a huge impact on New Zealand ecosystems.
The damage to native forests can be seen all too clearly in many areas. Possums ignore old leaves and select the best new growth. Dairy and deer farmers have the added worry of possums spreading bovine tuberculosis and then of course there is the damage they can cause to you property as often they will find a way into roof spaces and even into the living space.
How to get rid of possums in your home
The only way is to use a pest control professional, this is achieved by either snap traps or a baiting program how ever its often not a quick process and can take days to months.
