The answer to 'which is better mouse or rat' is that mice are generally considered a better pest to deal with compared to rats. Mice are smaller, less aggressive, and cause less overall damage than rats. However, both rodents can be problematic and pose health risks if they infest a home.
Mice are typically easier to trap and remove than rats, which are larger, stronger, and more difficult to get rid of. Mice also tend to be less destructive, chewing through fewer materials and causing less structural damage. Additionally, mice are less likely to bite or attack humans compared to rats, which can be more aggressive. That said, both mice and rats can spread diseases, contaminate food, and cause other problems in a home, so prompt removal is important regardless of the specific pest.
