What siding deters woodpeckers?

One type of siding that deters woodpeckers is metal siding, such as aluminum or steel. Woodpeckers are less likely to peck on metal surfaces due to the hardness and lack of insects within the material. Another option is fiber cement siding, which is also unappealing to woodpeckers due to its durability and lack of insects. Additionally, vinyl siding can be a deterrent as it is smooth and offers no insects for the birds to feed on.
