I'm not sure on using "foil" but I do know two things that will.

If you only have 1-2 trees where they're active, hanging a JUMPING SPIDER close to where they land will assuredly keep them away. IN most cases they'll start foraging elsewhere and within a week you can take down the spiders using them as needed throughout the year.

Another option is to lightly wipe down the trunk and tree limbs they're using with some 4-T-B REPELLENT. It's a non drying glue like product that lasts a few months. They won't like landing on it and will avoid any place it's applied.

Woodpeckers, like other birds, get territorial from time to time every year. During this time they instinctively establish territories and will even confront birds they see in what they believe to be "their turf". Windows can reflect images and many times birds will see themselves but mistake the image to be another bird. This is most likely what's happening at your house.

Generally this wouldn't be a major problem and since it only lasts a short while, there is a good chance the activity will stop. But in many cases the bird will get conditioned to seeing his reflection and if left to go on "fighting" with himself, the behavior can continue much longer than normal. This is when it becomes a problem.

The best way to deal with this behavior is to set out some Bird Tape which are featured in our Woodpecker Control article. Set some up over each window and any window where the pecking is happening. If the Tape doesn't do the trick, set out a Jumping Spider. This will definitely get them to move away.

Chasing nuisance woodpeckers away can be done if you are able to place some Bird Tape or a Jumping Spider where they're active. Sometimes this is tough but both deterrents do a good job of repelling them. If they're on the side of the house, use the Jumping Spider and anchor it to the soffit or roof overhang. If they're around windows, use the Bird Tape. We have more options listed in our Woodpecker Control article.

Most species of woodpeckers will "sound" during the spring as described in our Woodpecker Control article. This could be a random thing but many times they will tend to use one side or section of the house. You should be able to get them to move away by installing a Jumping Spider or Bird Tape. These visual/motion deterrents do a good job of alarming woodpeckers and make them uncomfortable enough to get them to go elsewhere. I suggest you set either or both of these repelling devices up where he is most active and see if you can get him to stay away.

Wood peckers will sound this time of year and commonly use homes for this purpose. Gutters will echo when pecked at and this is exactly what they're trying to accomplish so once they start, they won't quit. You need to set up some Bird Tape or Jumping Spiders where they most frequent. As our online article about wood pecker control explains, once they encounter the Spider or Discs, they'll stay away and reroute their behavior.
