Answer: Woodpeckers can cause a lot of damage to a house! Several years ago, I noticed drywall dust on my bedroom nightstand, looked up, and discovered a hole in the wall. A pileated woodpecker had pecked through the cedar siding, sheeting, insulation, and drywall, causing $1,000 worth of damage. I then discovered that insurance doesn’t cover damage from birds. During the past week I have been chasing them off the house every time I happen to hear rat-a-tat-tat.

Wood siding, especially soft wood like cedar, attracts woodpeckers who leave behind holes ranging in size from one-fourth inch to one inch or more. Woodpeckers peck for three reasons: communicating, feeding, or roosting. They often focus on the area just below the eaves. The “drumming” you hear is the woodpecker searching the house for hollow spaces.

One or two larger holes (an inch or more) are typically a sign of roosting or nesting behavior. It is critical to take action as soon as a woodpecker starts making holes in your siding, and before it has time to make it a part of its routine.
There are some techniques you can try to scare off your woodpeckers, but before you begin, cover or repair any existing holes. For small pea-sized holes,
