When woodpeckers start banging on your walls or roof, they are probably looking for insects to eat, storing nuts for winter, drilling a hole to make a nest, or communicating with other birds to establish territory or find a mate.

The size of the hole can help determine the reason for the pecking. Small irregular holes are a result of insect hunts. Acorn holes are more consistently sized and often fitted with a nut in the middle. Nest holes are large and have rounded edges. If the bird is pecking to mark its territory or attract a mate, it may leave dents rather than holes, and the noise will stop when the mating season starts in spring.

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.

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.

Birds eat grass seed for one simple reason—it’s delicious! The seeds are rich in nutrients such as carbohydrates, proteins, and fats. Seeds are also high in energy, so humans eat trail mix loaded with seeds and nuts for long-distance activities. Grass seed, when unprotected, is also exceptionally easy to access.
