The answer to 'which is worse rat or' is that both rats and mice can be serious pests that can cause significant damage and pose health risks to homeowners. However, rats are generally considered the more problematic of the two, as they tend to be larger, more aggressive, and cause more extensive damage.
Rats are known to chew through wires, insulation, and building materials, which can lead to fires and structural damage. They also contaminate food sources and can spread diseases like salmonella, hantavirus, and leptospirosis. Mice, while still a nuisance, are typically smaller, less aggressive, and cause less severe damage compared to rats.
