Easy to get in. Hard to get out.
Squirrels are common home and building invaders, often nesting and giving birth in an attic, soffit, or ventilation system. Inspect your home periodically to make sure your home is free of gaps where squirrels can enter and make nests. Once inside, squirrels are difficult to remove as they consider your home to be their new home. Trapping, tunneling, and exclusion are usually the only means of ridding your home of their presence. After squirrels have been removed, exclusion is recommended to keep other squirrels from moving in.
