The answer to 'which is better mouse or rat' is that mice are generally considered the less problematic pest compared to rats. Mice are smaller, reproduce faster, and are more likely to infest homes and buildings. While both can spread diseases and cause property damage, mice are generally less aggressive and destructive than rats.
Mice are typically easier to control and remove from a home compared to rats. They are more likely to enter through small cracks and openings, while rats require larger entry points. Mice also tend to be more cautious and less likely to chew through materials like electrical wiring. However, rats can be more difficult to eliminate once they establish a presence in a home.
