CEDAR ALPHA Bluebird House Predator Guard – Stainless Steel, 1.5-Inch Opening, 2-Pack

Protect nesting bluebirds with a durable predator guard

Protecting bluebird nests starts at the entrance. The CEDAR ALPHA Bluebird House Predator Guard is a stainless steel shield designed for a 1.5-inch opening. This 2-pack helps you shield a single box or equip multiple sites with a simple, durable solution.

Designed specifically for Eastern bluebird boxes, the guards surround the entry hole without blocking airflow, creating a barrier against chewing damage while keeping the entrance accessible to the parent birds.

What’s in the package

• 2 stainless steel predator guards
• 38 mm (1.5 inch) hole sizing; square ring design
• Approximately 9 x 9 cm footprint per guard
• 24 screws included for fast mounting
• Anti-rust stainless steel construction for outdoor use

Key benefits and use cases

• Protects the entry hole on most birdhouses, reducing damage risk from chewers
• Compact, sturdy design fits a wide range of housings while preserving access for birds
• Easy to install with included screws and simple alignment
• Ideal for backyard habitats, gardens, and wooded settings where bluebirds nest

How it works and maintenance: position around the hole, secure with screws, and inspect during seasonal checks. While it does not guarantee outcomes, many users report greater nesting stability and reduced worry about entry damage when birds are present.

Materials and durability

Constructed from anti-rust stainless steel, the guard resists corrosion from rain and humidity and stands up to repeated handling and outdoor exposure. The compact form stores neatly when not in use.
