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.

Some pest control treatments, such as spraying insecticides or bug bombs, can cause severe health problems for your household members if you are improperly exposed to them. That's why putting away pet toys, dishes, bedding, children's toys and items is essential. Pest technicians are trained to reduce risk, but it's best to take caution by avoiding the risk of items being accidentally sprayed. Discuss any concerns you may have with your pest control specialist.

Moles eat insects, so grub removal is another important way to prevent moles from destroying your yard.

Probably not. Many imitation nests are meant to be hung from trees or other tall places, but not all yellow jackets nest up high—most species, such as the common yellow jacket and the southern yellow jacket, build nests in the ground.
