How many litters can a house mouse produce in a year?

1. About 2

2. About 5

3. About 6

4. About 8

The correct answer is: About 8

A house mouse can produce about 8 litters in a year, making it a particularly prolific breeder. Each litter typically consists of around 5 to 6 young, although this number can vary. This high reproductive rate is essential for the species' survival in various environments, as it allows populations to grow rapidly and adapt to changing conditions. House mice reach sexual maturity at a young age, usually within 5 to 6 weeks, which contributes to their ability to produce multiple litters each year. The gestation period is relatively short, lasting about 19 to 21 days, allowing them to reproduce quickly and often throughout the year, depending on environmental conditions. This characteristic breeding behavior emphasizes the importance of effective pest control strategies, as even a small number of mice can lead to a significant infestation within a short time if not managed properly. Understanding their reproductive capabilities is crucial for pest management professionals when devising control methods to prevent large populations from establishing.
