You might need squirrel removal if you hear scratching or scurrying noises in your attic or walls, especially during early mornings or evenings when squirrels are most active. Check for chewed wires, damaged wood, or torn insulation, as squirrels like to chew to keep their teeth sharp—this damage can be dangerous and expensive to fix. You may also find piles of droppings or shredded nesting materials like leaves or fabric, showing squirrels have made a home nearby. A strong, unpleasant smell inside your attic or walls often comes from squirrel urine or nesting and can cause health problems. Additionally, if your garden plants are dug up or bird feeders emptied quickly, squirrels are likely causing the mess while searching for food.
