Protecting Bluebird Houses from Squirrel Damage

Best Solution: Metal Predator Guard

• Install a metal plate with 1.5-inch hole over the entrance.
• Screws secure it; squirrels won't chew metal.

DIY Alternative

Use ¼-inch hardware cloth (welded wire), firmly attached, with wire snips forming a bird-sized hole.

Why It Works

Squirrels enlarge holes to access nests. Metal stops them cold while allowing bluebirds entry.
