Why woodpeckers peck holes in houses

Woodpeckers can cause a great deal of property damage and sleepless mornings by drumming on your house. The good news is that 50 percent of the time, the birds stop pecking on houses within two weeks whether you do anything or not. Even so, it is probably best to try to break the woodpeckers drumming before it becomes a habit.

Why Woodpeckers Peck Your Home
Woodpeckers damage structures for basically three reasons:

1. Searching for insects or hiding food (Some people find feeding suet distracts a woodpecker from their house.)
2. Creating cavities for nesting and shelter (Sometimes putting a woodpecker house helps deter damage.)
3. Drumming to communicate. Like some birds sing, woodpeckers drum. There are different drumming calls that they may use: mating; alarm; or territorial. This can be heard over long distances, if they use a surface with adequate acoustic properties.)

Laws Woodpeckers are a federally protected bird under the North American Migratory Bird Act. So you can't use lethal control on woodpeckers without contacting your Federal Wildlife Officer.

Strategies to Control Woodpecker Damage
Unfortunately, there is no easy guaranteed solution. So with that being said, try the following strategies: 

1. Check for insects. Woodpeckers feed on insects in wood. Put out a suet feeder to divert the woodpeckers.
2. Cover all damage as soon as possible. Place aluminum flashing over the areas where the woodpecker is pecking. The flashing will stop the pecking at that spot because: a) it is metal, b) it changes the sound, and c) woodpeckers don't like shiny objects. Just make sure that the woodpecker is not living in your home.
3. Put up a woodpecker house. Woodpeckers roost and nest in cavities. They are very selective and tend to look for dead trees or snags that have a hard outer shell and a softer inner cavity. Sometimes even the soft cedar siding of houses are chosen for this purpose. When aggressive hole making is a problem, a simple solution is provide a man-made nest box directly at the site that is being damaged.
4. Scare the woodpecker away using one or more of the following:
  • Mylar tape: Wild Birds Unlimited has some Mylar tape (1-inch-wide strips) flutter ribbon you can hang in the area. Woodpeckers don't like shiny objects. If you don't have Mylar, hang tinfoil, aluminum pie plates, or old CDs or DVDs.
  • Mylar balloons: The dollar stores usually have shiny Mylar balloons you can hang in the area.
  • Garden hose: One animal damage controller recommends placing a garden hose with a sprinkler set at an angle to reach where the bird is drumming. The woodpeckers leave after a few squirts because they don't like hanging on to wet structures.
  • Exclusion techniques: If woodpeckers are damaging your siding under an eave, hang some netting from the eave line down to the ground. If the net is extended away from the house wall, the woodpecker can't get close enough to damage the wood.
If the attack is on windows and not just an accidental window strike, the likely behavior is a reaction to the bird seeing an intruder on its territory. A simple solution to this problem is to cover the window with screens or rub the window with a bar of soap to decrease the reflection. The Mylar tape or balloons also work to keep the birds away from your windows.
