House mice vary from light brown to dark grey and sometimes have a lighter colour on their bellies. They have large ears, small eyes and small feet. Their size ranges from 5 to 8 cm in length, weigh less than 28 grams, and their tail is usually the same length as their body.
Habits & Behaviours
House mice are one of the most common, invasive pest species that are active all year round. They can be found throughout Ontario and have lived amongst humans for many, many years within and around urban and rural residential, recreational/cottage, and commercial properties. Just the presence of a house mouse can be upsetting and frightening to many. Because house mice rapidly reproduce, they can infest a house very quickly. They have a tendency to become extremely annoying and troublesome, getting into stored food and polluting many areas throughout a property with urine and feces. House mice are primarily nocturnal and the surrying sounds of them searching about for food can be disturbing to occupants trying to sleep.
Complaints & Destruction
A house mice infestation can be extremely difficult to exclude and they are capable of doingconsiderable damage to your property. They are prevalent in urban areas and will nest in attics, wall cavities, garages, crawl spaces, storage areas, and even in pantries, cabinets and drawers. A house mouse can squeeze through a hole the size of a coin and will gnaw, and tear through almost anything to gain access to properties for food and shelter.
Both in search of food and in order to construct their nests, house mice will destroy and shred materials throughout the property, including fabrics, furnishings, wood, wiring, cables, cords, food containers, and insulation. A house mouse will consume small amounts of food several times day, but will destroy a considerable amount more than they eat, contaminating it with feces, urine and fur, They are capable of destroying massive amounts of food in places, such as rural, agricultural areas.
Major Risks & Dangers
Fires, electrical issues and power outages
House mice will chew electrical wiring and cables, which may result in costly repairs, power outages, and a serious risk of fire.
Structural and home efficiency damages
House mice will gnaw constantly in search of food, to gain access to properties, and to prevent their teeth from growing too long. This damage can destroy household appliances and cause costly damage and higher energy costs. In addition, these openings can make it easy for other nuisance animals to gain access to the property.
House mice contaminate food and various areas/materials throughout our properties with feces, urine and fur, which can cause illnesses and trigger allergies. They can spread diseases such as salmonella, lepospirae and typhus. Aditionally, they carry various parasites such as fleas, round worms, and mites that can transmit diseases to humans and domestic pets. Dead and decomposing house mice can infect drinking water, attract insects, and cause staining and putrid odours that can last for months.
House mice can mate all year round, reproducing at an astounding rate. A female is fertile every 4 to 6 days and has the ability to give birth to 10 litters per year. The average gestation period lasts20 days and the litter consists of 3 to 14 young. Therefore, a single pair of mice could potentially multiply into the hundreds within a single year. The young mature very quickly and reach sexual maturity at about 6 and 8 weeks old.
House mice are omnivores and although they prefer seed and gain, they will eat just about anything.
To reduce the risk of house mice invading and destroying your residential, recreational/cottage, or commercial properties, exclusion is the best prevention.
House mice are extraordinarily resilient and properly eliminating them requires knowledge of and experience with mice and their habits. If you suspect that house mice may be dwelling in your residential, recreational/cottage, or commercial property, it is best to let the professionals do the job of safely and humanely removing the animal(s).
