How to Fill Woodpecker Holes

Woodpeckers are stubborn; if not evicted as soon as possible, they can tunnel deep into wood structures.

Although woodpeckers probably don't know better than to drill into your siding to search for food or attract mates, having to frequently replace siding is a tedious task. Even worse, the more holes you have, the more woodpeckers will be attracted to your house. Instead of replacing your siding -- or just leaving the damage -- you can restore your siding inexpensively by filling in the holes.

Things You'll Need

• Waterproof putty, such as auto body putty
• Putty knife
• Expanding foam spray

Instructions

1. Prepare waterproof putty according to package directions. Auto body putty is easy to find and is excellent for filling holes in siding, because it's waterproof and can easily be sanded.

2. Fill the holes generously with putty, using the putty knife. Let the putty dry overnight. Alternatively, you can use expanding foam spray to fill woodpecker holes. This also will need to dry according to package directions.

3. Sand the putty or foam until the surface is flat and smooth. Paint it to match the surrounding area.

Tips & Warnings

• Prevent new unwanted visitors by deterring them with reflective objects such as mirrors and aluminum foil, or with natural woodpecker repellents.
