Which rodent is known to have up to 8 litters per year?

Mice are known for their prolific breeding capabilities, averaging up to 8 litters per year under optimal conditions. Each litter typically contains around 5 to 10 young, making mice particularly adept at quickly increasing their populations. This high reproductive rate is one reason why they can become significant pests in homes and agricultural settings.

In contrast, while rats also reproduce frequently, they generally have fewer litters annually compared to mice. Squirrels and hamsters have much lower reproductive rates and do not match the litter frequency of mice. Understanding the breeding habits of these rodents is crucial for effective pest management practices, as it highlights the importance of early intervention to prevent infestations.
