The answer to 'how did inspection get in my house' is that there are several common causes for pests getting into your home, including cracks or gaps in the foundation, walls, or roofing, as well as improperly sealed windows and doors. Pests may also find their way in through vents, chimneys, or other openings. Signs of a pest infestation can include droppings, nests, damage to wood or wiring, and even seeing the pests themselves.
If you suspect a pest problem, it's important to act quickly to address the issue. While some minor infestations can be treated with DIY methods, it's often best to call a professional pest control technician. They have the expertise and equipment to properly identify the pests, locate the entry points, and implement an effective and safe treatment plan.
