As a pest control expert with years of experience in dealing with rodent infestations, I can provide you with a comprehensive guide on how to identify the entry points of mice in your home.

Step 1: Inspection
The first step in finding out where mice are entering your home is to conduct a thorough inspection. Look for signs of mouse activity such as droppings, gnaw marks, and tracks. Mice are nocturnal creatures, so it's best to inspect during the day when they are less active. Pay close attention to areas where you have seen signs of infestation.

Step 2: Identifying Entry Points
Mice are adept at squeezing through small openings. They can enter through gaps as small as a dime. Common entry points include:

- Doors and Windows: Check for gaps around doors and windows. Weather stripping can help seal these gaps.
- Ventilation and Utility Openings: Mice can enter through openings for vents, pipes, and wires. Inspect these areas carefully.
- Cracks and Holes: As mentioned, mice can enter through cracks and holes in walls, floors, and foundations. Look for any openings that are larger than a dime in diameter.
