Keep Rodents Out of Your Roof Space or Shed via Whirlybirds
Rodents, birds, and other pests can easily enter roof spaces through unprotected whirlybirds and roof vents, causing damage to insulation, wiring, and timber. Many homeowners use our whirlybird ember guard as a simple, effective way to block rats, mice, and other unwanted animals from accessing their roof space or shed.
Unlike external covers or temporary solutions, our guards are designed to fit directly inside whirlybird roof vents, creating a durable physical barrier that stops pests without restricting airflow or ventilation performance.
Whether you’re in a bushfire-prone area or simply dealing with ongoing rodent issues, this provides a practical, low-maintenance way to protect your home or shed long-term by preventing pests from entering through your whirlybird roof vent.

Why Rodent Protection Matters
Rodents and birds can cause more than just a nuisance — they can:
- Chew wiring, creating fire hazards
- Damage insulation and roof structures
- Carry disease that can affect humans or pets
- Leave droppings that lead to odors or contamination
Our guards are made from 304 stainless steel mesh (0.6 mm wire, 1.6 mm aperture). Originally designed for bushfire protection, they are strong enough to keep out rats, mice, and small birds while maintaining proper airflow for your roof ventilation.
Features & Benefits
High-quality stainless steel: Durable and weather-resistant for long-term protection.
Dual-purpose: Protects against both bushfire embers and pests.
Easy to install: Fits inside the whirlybird throat, no special tools required.
Maintains ventilation: Mesh design ensures your roof still breathes.
Compliant with AS3959: While designed for bushfire protection, installation does not interfere with roof standards. Learn more about installation.
How It Works
The guard forms a barrier between the whirlybird inlet and your roof space. Rodents and small animals cannot pass through the 1.6 mm mesh openings, while airflow continues unimpeded.
By adding these guards, you reduce the risk of;
- Roof contamination by pests
- Damage to insulation and wiring
- Secondary fire risks caused by gnawed electrical cables
Installation & Maintenance
- Remove the whirlybird spinner (usually three screws).
- Place the ember guard on the internal ledge inside the whirlybird throat.
- Reattach the spinner.
No specialist tools are required. Occasional visual checks are recommended to ensure the mesh remains free from debris. See full FAQ
