Woodpeckers usually feed on homes when there is a food source present, and termites are one possible source. However, the presence of woodpeckers doesn’t necessarily mean there are termites. They may also be feeding on more harmless insects like ants or spiders. If woodpeckers seem drawn to one particular part of your home’s siding, it might be worth hiring a termite inspector to check for the presence of these pesky critters.

This depends on if their needs are being met. They'll likely return night after night if they have access to food, water, and adequate shelter. If this changes, they’ll look for another roosting spot. This is why bright lights and other dissuading factors often work when removing bats from a property.

DIY animal removal is rarely a good idea and is not advised for many reasons. First, these types of animals can carry diseases and, therefore, pose a health risk to you, your family, and your pets if mishandled. Second, depending on your city or municipality, it may be illegal to remove or handle wildlife yourself. 

Sealing your home against these animals yourself is also a bad idea. Trapping an animal under your house will cause odor and insect problems when it passes away. 

High-frequency bird repellent devices are effective at driving away birds, which is their intended purpose. However, these devices also tend to have unintended negative consequences. For example, if you or your neighbors own pets, the high-pitched noise emitted by these electronic devices will cause them distress and may even make them aggressive.
