Uninvited Guests: Why Mice Cause Pest Issues in Autumn and Winter Months

As the winter chill sets in, many creatures seek refuge indoors. 

While some of us enjoy the cosy comforts of our homes during this time, there are unwelcome guests that take this opportunity to invade our living spaces. 

Mice, those small, seemingly harmless creatures, can turn into significant pest problems during the autumn and winter months. 

In this blog post, we’ll explore why mice become a nuisance during these seasons and why Shield Pest Control is your best ally in keeping your home pest-free.


Uninvited Guests: Why Mice Cause Pest Issues in Autumn and Winter Months


Seeking Shelter from the Cold

The primary reason why mice become a major pest issue during autumn and winter is simple survival. As temperatures drop, mice, like other small rodents, seek refuge from the cold. Your warm and snug home provides them with the perfect haven. They enter through tiny cracks, gaps, or open doors and windows, often unnoticed until the damage is done.

Increased Reproduction Rates

Mice are prolific breeders, and their reproductive activity tends to increase during the autumn and winter months. A single female mouse can produce up to 35 offspring per year, and with favourable conditions indoors, they can reproduce even more frequently. This rapid multiplication can lead to a full-blown infestation if not addressed promptly.


Increased Reproduction Rates

Food Sources Become Scarcer

As autumn progresses into winter, natural food sources for mice become scarcer. Outdoor vegetation dies off, and their usual food supply dwindles. This scarcity drives mice to venture indoors in search of sustenance. They’ll forage for crumbs, pet food, and even chew through packaging to access stored goods in your pantry, causing contamination and damage.

Gnawing and Chewing Habits

Mice are notorious for their gnawing and chewing habits. Their teeth grow continuously, so they must constantly gnaw on objects to keep them at a manageable length. During the autumn and winter months, when they invade your home, they’ll chew on anything they can find, from electrical wiring to wooden structures. This not only leads to costly repairs but also poses significant safety hazards, including the risk of electrical fires.

Disease Transmission

Mice are not just a nuisance; they can also be carriers of diseases. They can transmit diseases like Hantavirus, Salmonellosis, and Leptospirosis to humans through their urine, faeces, or saliva. With mice more likely to seek shelter in your home during colder months, the risk of disease transmission increases significantly.

Foul Odours and Allergies

Mice leave behind more than just physical damage. Their urine and faeces can create foul odours that permeate your living space. In addition to being unpleasant, these odours can trigger allergies and respiratory issues, especially in individuals with sensitivities.
