No, mothballs do not keep bats away. Not only are mothballs completely ineffective when repelling or removing bats, but using them could be illegal, depending on where you live. Remember, bats are federally protected, and it's illegal to use chemicals during the removal process, and mothballs tend to fall into this category.

The best animal repellents for gardens include a variety of different scents. You can use predator urine to keep away deer, raccoons, squirrels, and more. The odor will tell the critters that your yard is a dangerous place. Other scents that repel critters are herbs like lavender, geranium, and mint. You can also use hot pepper, garlic, and strong-smelling soap.

An owl's worst enemy in the wild is often other raptors and environmental factors. Among the avian threats, larger owls or other birds of prey can pose a danger, engaging in territorial disputes or competing for food resources. Terrestrial predators like foxes, raccoons, and larger mammals may target owl nests or young fledglings. Environmental factors like severe weather conditions, habitat loss, and food availability changes can also significantly impact owl populations.

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.
