The answer to 'how did rodent get in my house' is that rodents can find their way into homes through a variety of entry points, including small cracks, holes, and openings around pipes, vents, and wiring. Rodents are excellent climbers and can squeeze through very small spaces to gain access to your home, seeking shelter, food, and warmth.
Common signs of a rodent infestation include droppings, chewed wires or food packaging, and noises in the walls or attic. Rodents can cause significant damage and pose health risks, so it's important to address the problem as soon as possible. In many cases, homeowners can take DIY steps to seal up entry points and set traps, but for severe infestations or difficult-to-reach areas, it's best to call in a professional pest control technician.
