Woodpecker holes in siding or trim

Woodpeckers drill into wood siding or trim either searching for insects or to establish territory, and repeated damage often needs deterrents, not just patching.

Symptoms

  • Small to large round holes in wood siding, trim, or fascia
  • Pecking sounds heard against the house, especially at dawn
  • Holes often clustered in one area, sometimes near a corner

Likely causes

  • CommonWoodpeckers foraging for insects in the woodHoles often indicate insects like carpenter bees or ants are already active in that wood.
  • CommonTerritorial or mating drumming behaviorWoodpeckers sometimes peck loudly on resonant surfaces just to make noise, without seeking food.
  • PossibleNesting cavity excavationA larger, deeper hole may be an attempt to create a nesting spot.

What to do

  1. Inspect the holes for signs of insect activity, like sawdust-like frass or actual insects, which the bird may be after.
  2. If insects are present, treat or have the wood treated for carpenter bees, ants, or other pests as the root cause.
  3. Fill smaller holes with exterior wood filler, sand smooth, and prime and paint to match.
  4. Hang reflective tape, wind spinners, or a fake predator decoy near the damaged area as a deterrent, moving them periodically so the bird doesn't get used to them.
  5. Consider netting or hardware cloth over a repeatedly targeted area as a physical barrier.
  6. Avoid harming or trapping woodpeckers, which are protected under federal law in the US; use deterrents and exclusion instead.
  7. Replace badly damaged boards if holes are large or numerous.

When to call a pro

Call a pest control company if carpenter bees or other wood-boring insects are the underlying draw, and a wildlife control professional for persistent woodpecker problems.
