Keeping your pool cover clean is a good way to keep smaller animals from running across it or using it as shelter. Small animals may use leaf debris on top of the cover to hide. Cleaning also removes nuts that may fall from a nearby tree that could otherwise be a tempting snack for some animals, like squirrels. 

To keep animals out, you must prevent them from entering. As long as they can get in, the problem will persist. That said, consider making your attic less inviting using deterrents like motion-activated lights or ultrasonic devices. Additionally, keeping a well-maintained, clean, and uncluttered attic that you regularly inspect for activity may make the space less attractive to critters.

Some animals, such as bats or birds, will be able to get out of chimneys on their own since they can fly. Other animals, however, may have a harder time and will require the help of a professional to escape. Squirrels and raccoons in particular may become stuck inside a chimney, especially if you have a buildup of soot or creosote inside. This can prevent them from being able to climb out, in which case you’ll need to call an animal control expert to help remove them.

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.
