MICE
Rodents comprise the largest group in the mammalian kingdom, representing 42% of all mammal species. There are four families of rodents, the largest of which is the Muridae family. All mice are part of a sub-family called Murinae (Murine rodents).
Mouse populations exhibit very high reproductive rates, females often being able to produce litters of between 6 and 10 young every 4 to 5 weeks. Historically, mice were always thought to be less intelligent than rats, but recent research has shown them to be as intelligent and equally adaptable and agile. Like rats, their incisor teeth grow continuously throughout their lives and are strong and sharp – they are able to gnaw through wood, lead, aluminium, tin and wiring. Mice are abundantly present in Myanmar, often causing serious economic loss and damage, as well as placing both the environment and the health of the human population at risk.
HOUSE MOUSE (Mus castaneus)
APPEARANCE:
Averaging about 17 – 20g, House mice are moderately large mice compared to other species, with long tails that are usually slightly longer than the head and body combined. Their coat is usually plain brown or grey brown with belly fur of a similar colour.
BEHAVIOUR AND DIET:
House mice are curious and explorative in nature, unlike most rat species. They roam freely and like to eat nuts, grain and other cereal-based products.
In northern climes, when temperatures outside begin to drop, house mice, since they don’t hibernate, begin searching for a warmer place to live. Often attracted by the smell of food and the warmth of a structure, the house mouse can use any opening, such as utility lines, pipe openings, and gaps beneath doors, to gain entry into a home. In the tropics, the attractant is not warmth, but more broadly, shelter and food.
REPRODUCTION:
House mouse average litter sizes can be from 6 – 10 young and females can produce litters every 4 – 5 weeks.
VISUAL SIGHTINGS: Usually occurring in buildings, often at high populations.
DROPPINGS – Small pellets are commonly found anywhere the animals have visited or travelled. Approximately 3 to 6 mm long, the droppings may be rod shaped with pointed ends.
ODOUR – House mice use urine to communicate with each other. This has a distinct odour which may become noticeable when infestations grow large.
DISEASE TRANSMITTERS. Their habit of living in very close association with human populations, increases the risk of food contamination and disease transmission via their faeces and urine to humans. Similarly to rats, house mice spread Leptospirosis which can result in Kidney failure.
DAMAGE. House mice can cause damage to all manner of materials including electrical wiring and communications systems.
