Since mice are known to carry diseases, contribute to allergies and asthma, and cause fire danger by chewing through electrical wires, you want to take care of any rodent problem in your home while it is still manageable. Mice reproduce extremely quickly, so even a small mouse problem can quickly turn into a full-blown infestation.
Mice are born blind and hairless, but they grow and mature quickly. By 6-8 weeks old, they are sexually mature and capable of reproducing. After mating, a female mouse is pregnant for only 19-21 days before giving birth. The average litter size is between 6-8 pups, but can reach as high as 14.
To make matters worse, a female mouse is capable of getting pregnant again immediately after giving birth. On average, a female mouse has between 5 and 10 litters of pups every year. This means that each female mouse can produce approximately 60 babies each year on average. When you consider all of her posterity that will also produce offspring, you are looking at a huge number. In ideal circumstances if everything happened just right, you could theoretically get over 100,000 mice in one year, as the American Fancy Rat and Mouse Association (AFRMA) diagramed. Even though these numbers are only theoretical and highly unlikely, they show why rodent control is essential.
Mice in the wild face harsh environments and many predators, so their actual reproductive rate is much lower than the above scenario shows. They typically do not produce offspring during the coldest months of the year, and the survival rate of the babies is also lower. An average lifespan for a wild mouse is less than 12 months. Indoor mice that have to deal with less of these stresses tend to live much longer, up to 2-3 years, and will reproduce all year long.
These numbers may seem staggering, but if you take the right preventive measures and ensure that rodent problems are dealt with as soon as possible, you can maintain a rodent-free home and Harris can help. Harris home pest control products allow you to take back control of your home.
