Tree Guards — Reducing Possum Access via Trees
Trees can provide possums with a route towards roofs and buildings. Where a tree forms part of the identified access route, a purpose-designed Tree Guard may help restrict that pathway as part of the overall possum-proofing approach.

How Trees Can Provide Possum Access
Possums are capable climbers, and nearby trees or branches can sometimes form part of the route they use to reach a roof. The important question is not simply whether a tree is nearby, but whether it forms part of the access route at that particular property.
Tree trunks
A tree trunk may provide the climbing route that allows a possum to move towards the roof or another part of the building.
Overhanging branches
Branches extending towards a roof can provide another possible pathway from the tree to the building.
Other access routes
Trees are only one possibility. Nearby structures, overhead cables and building features may also form part of the access route.
Assess before proofing
The relevant access route should be identified before deciding which proofing measure is appropriate.
What Is a Tree Guard?
A Tree Guard is a physical barrier fitted around a tree trunk where that trunk forms part of an identified possum access route. The Possum Man uses purpose-designed Tree Guards, including polycarbonate guards where appropriate, to help restrict that route.

Purpose-designed sheeting
The Possum Man uses purpose-designed materials, including polycarbonate sheeting fitted around the trunk where suitable.
Property-specific approach
Every installation depends on the tree, its relationship to the building structure and safe access at the property.
Tree Guards are property-specific. Whether one is appropriate depends on the tree, its relationship to the building and the other access routes present at the property.
Tree Guards Are One Part of Possum Proofing
A Tree Guard addresses a particular type of access route. It does not replace the need to identify and address relevant entry points or other ways a possum may be reaching the building. Possum proofing considers the property as a whole so that the relevant access and entry issues can be addressed rather than relying on one measure in isolation.
Tree Guard or tree trimming?
Where branches provide the pathway towards the roof, increasing clearance may form part of the recommended approach. Where the tree trunk itself forms an important part of the access route, a purpose-designed Tree Guard may be considered. In some situations more than one access route may need to be addressed.
Tree & vegetation access
Nearby trees and branches can provide climbing access towards roofs and gutters, which may call for trimming or a Tree Guard.
Roof & gutter access
Where possums reach valley lines or gutter edges, access-control measures such as Valley Guards or Gutter Guards may be considered.
Other access routes
Nearby structures, overhead cables and building features may also provide access and require separate assessment.
If a possum is already in the roof
Restricting a tree access route does not by itself remove an animal already occupying the roof. Possum removal and proofing need to be considered together.
How Tree Guard Assessment & Installation Works
Tree Guard installations are property-specific. Here is what to expect from initial contact through to assessment, quotation and installation.
- Step 1
Listen
We start by understanding what you've been experiencing and where the activity is occurring.
- Step 2
Inspect
We inspect the property to identify whether a tree forms part of the possum's likely access route and consider other possible pathways.
- Step 3
Assess
We determine whether a Tree Guard, vegetation management or another proofing measure is appropriate.
- Step 4
Recommend
If a Tree Guard is suitable, we explain the recommended approach and provide a quote for the work.
- Step 5
Install
If you proceed with the recommended Tree Guard work, installation is carried out where safe and suitable access is available.
- Step 6
Address the access route
The Tree Guard forms part of the approach to restricting the identified tree access route, while other relevant access or entry issues are considered separately.
Tree Guards Are Quoted After Inspection
Tree Guard installations are quoted after inspection because the appropriate solution depends on the tree, access and conditions at the property.
- Step 1
Inspection — $279 + GST
Your inspection allows us to assess the relevant access routes and determine whether a Tree Guard is appropriate. If Tree Guard work is recommended, the installation is quoted following the inspection.
- Step 2
Tree Guard — Quoted after inspection
Where suitable, purpose-designed Tree Guard work is priced specifically for your property following the on-site assessment.
- Step 3
Pricing & access conditions
Some properties may require additional access or equipment. If this applies, we'll let you know before the work proceeds. See our Pricing & Terms for further details.
A Tree Guard addresses a relevant tree access route as part of an overall possum-proofing plan. It does not replace possum removal or proofing where these are required, and the property must still be assessed for other access routes.
