Squirrels build their nests, called dreys, using leaves, twigs, and other materials. These nests are usually found high in trees. But in cities, squirrels often make nests in attics, chimneys, or even inside walls. If you hear scratching sounds in your attic or find droppings, a squirrel may have moved in. To handle the problem safely, you can rely on squirrel control services or professional squirrel removal. For long-term prevention, consider expert rodent control solutions to keep your home squirrel-free.
