Woodpecker
Woodpeckers drill into wood siding, stucco, and EIFS, causing costly exterior damage.
How to identify
Varied sizes, 6 to 19 inches, with chisel-like bills, stiff tail feathers, and black, white, and red head markings.
Why it is a problem for commercial facilities
Woodpeckers drill holes in wood siding, stucco, and EIFS while foraging, drumming, or nesting. Open holes let water into wall systems and invite more damage.
Protected status
Federally protected under the Migratory Bird Treaty Act (MBTA). Birds, active nests, and eggs cannot be harmed or disturbed without a U.S. Fish and Wildlife Service permit. Deterrents and exclusion installed before nesting do not require a permit. Visual deterrents and repairs after birds leave do not require a permit.
How BSI controls it
- Wall netting systems over affected facades
- Electrical track along upper edges and parapets
- Patch repair of existing holes, coordinated so active cavities are not disturbed
Where we see it most
Common questions
Can woodpecker holes be repaired right away?
Yes, unless a hole is an active nest cavity. Repair inactive holes promptly to discourage return visits.
What stops woodpeckers on EIFS?
Lightweight netting across the affected wall area physically blocks access.
