If you spot the Polyphagous Shot Hole Borer (Stompkopkewer) or suspect that a tree may be infested, please report it to us immediately so that appropriate action can be taken.
The municipality has a Contingency Plan in place and is actively collaborating with researchers and students from Stellenbosch University to mitigate the spread of this invasive beetle.
Signs of an Infested Tree to Watch For:
- Tiny, randomly spaced holes in the bark
- Fusarium (fungus) staining
- Sawdust or a light wooden powder on or around the tree
- Wilted or missing leaves
- Dead or dying branches
- Glue/Sap oozing from the holes
- Light spots on the bark
What We’ve Done So Far:
A handful of infested trees have already been positively identified within the municipal area, both on private properties and public land. These trees have been felled, and strict protocols are being followed to safely transport and destroy the infested wood.
Infected trees must be:
- Felled and chipped.
- Covered with black bags/plastic for at least 6 months to smother the beetle.
- Removed or destroyed by incineration after this period.
- Important: Wood from infested trees should never be moved to another location such as a landfill site, as this could allow the beetle to spread and infect other trees.
What to do when you suspect a tree is infested:
- Step 1: Call Environmental Management offices at the following numbers: 021 808/ 8132/ 8194/ 8109/ 8194. Alternatively send an email to: trees@stellenbosch.gov.za
- Step 2: Ensure that the tree is identified by name and address.
- Step 3: Indicate whether tree(s) is on Municipal or Private Property.
- Step 4: Trees on Private Property: The Municipality will provide guidance on the way forward. The municipality is not permitted to work on private property but will assist with advice, proper procedures, guidance on possible service providers.
- Step 5: Trees on Municipal Property: The Municipality will take the necessary action.
