Understanding Possum Behaviour
The common brushtail possum is nocturnal, intelligent and highly adaptable. Possums repeatedly return to the same feeding routes unless strong deterrents are in place.
- Nocturnal – most active at night.
- Excellent climbers that can access roofs and trees easily.
- Opportunistic feeders that target fruit, flowers, vegetables and pet food.
- Known to damage insulation, wiring and native plants.
Signs of Possum Activity
Around the Home
- Heavy thumping on the roof.
- Scratching or chewing noises in ceilings.
- Droppings around decks, roofs or fences.
- Damaged insulation or gnawed timber.
In the Garden
- Missing or half-eaten fruit.
- Stripped leaves, flowers and shoots.
- Broken branches from movement.
Near Native Plants
- Chewed stems and foliage.
- Missing buds and flowers.
Why Possum Control Is Essential
- Possums destroy gardens and orchards.
- They damage homes by nesting in roof cavities.
- They threaten native wildlife and plants.
- They can spread parasites and disease.
Best Possum Control Methods in New Zealand
1. Ultrasonic & Sonic Electronic Repellers
Electronic repellers emit ultrasonic and sonic frequencies that possums find uncomfortable. They activate instantly when movement is detected.
2. Solar Water Jet Repellers
Motion-activated water jets scare possums away using a sudden burst of harmless water. Ideal for gardens, lawns and fruit trees.
3. Physical Barriers & Spikes
Install spikes along fences, gutters, beams and pergolas to block climbing routes and prevent access to roofs or fruit trees.
4. Possum Pellets (First-Generation Bait)
These pellets require multiple feeds and kill possums within 4–10 days. Use only in approved bait stations.
How to Choose the Right Possum Product

Use ultrasonic repellers + install spikes on access routes. - Possums in the Garden
Use water jets + ultrasonic units + physical barriers. - Large Population Problems
Use first-generation bait in approved stations + deterrents. - Humane Options Only
Use repellers, water jets and spikes without poison.
