Australia is home to several species of mice, including the common house mouse, the field mouse, and the hopping mouse. The house mouse, in particular, is considered a pest due to its ability to thrive on a diverse diet, including human food, and its adaptability to various environmental conditions. The house mouse's diet consists of grains, vegetables, meat, fruit, and dairy products, with a preference for high-protein grains and aromatic vegetable oils. They consume approximately 3-5 grams of food daily and can survive without additional water if their diet provides sufficient moisture. The field mouse, on the other hand, prefers to stay away from inhabited buildings but may seek shelter in outhouses and sheds during the winter, where they can access stored fruits and vegetables. The yellow-footed antechinus, also known as the marsupial mouse, is a native Australian animal that feeds on insects, reptiles, and even smaller mice. Lastly, the hopping mouse, with its long, narrow hind legs, has a diet that includes seeds, berries, plants, insects, fungi, and small reptiles, and they can meet their water needs solely from their food sources.

Australian mice eat a wide range of foods, including grains, vegetables, and meat
Australian mice are omnivores, and their diet includes a wide range of foods, from grains, vegetables, and fruits to meat. They are known to eat around 3 to 5 grams of food daily and can survive without any additional water as long as their diet contains at least 15% moisture. In the wild, mice eat the seeds of native grasses and grains, such as maize, wheat, oats, barley, and sunflower. They also feed on newly sprouted seedlings and maturing crops, causing significant damage to plants like wheat, oats, barley, and maize.
Mice are highly adaptable and can live off a variety of food sources, including human food. In food storage areas, they may consume cereals, vegetables, meat, fish, bread, biscuits, peanuts, cheese, rolled oats, rice, wheat germ, apple, and melon. They are particularly attracted to high-protein grains and aromatic vegetable oils. Mice will sample all types of food within their reach and may not return to a specific food source for several days. This behaviour is important to consider when selecting baits for mouse traps.
The common house mouse (Mus musculus) is an introduced species in Australia and is considered a pest due to its ability to thrive on a diverse diet and adapt to various environmental conditions. They are mainly found in urban areas and can cause issues by contaminating food, damaging property, and spreading diseases. House mice have short fur that varies in colour from grey, brown, to black, with a hairless tail that is about the same length as their body.
In addition to the house mouse, there are other mouse species in Australia, such as the field mouse and native species like the yellow-footed antechinus (Antechinus flavipes). Field mice are less likely to invade inhabited buildings but may seek out stored fruit and vegetables in outhouses or sheds during winter. The yellow-footed antechinus, also known as a marsupial mouse, is a small carnivorous marsupial that feeds on insects, reptiles, and even other mice.

They can survive without drinking water, as long as their food has a moisture level of 15%
Australian mice are typically omnivores, and their diet includes grains, vegetables, meat, fish, bread, biscuits, cheese, rice, fruit, and more. They are also known to eat the seeds of native grasses and weeds. In the wild, mice can survive on as little as 3 to 5 grams of food per day.
One interesting fact about mice is that they can survive without drinking water. As long as their food has a moisture content of around 15%, they can meet their hydration needs solely from their diet. This is particularly relevant for mice living in sheds or areas with limited access to water, as they only need 1-2 ml of water per day in such situations.
The ability of mice to adapt to different environments and survive without additional water sources has contributed to their reputation as pests in Australia. They can be challenging to keep out of buildings due to their swimming, digging, and jumping abilities, and they can cause damage to food packaging, crops, and stored produce.
Mice have a significant impact on crops, especially during the seedling stage when they feed on newly sprouted seedlings. They also damage maturing crops by gnawing at the nodes on the stems, causing developing seed heads to fall. In vineyards and vegetable crops, mice can cause heavy losses by eating and contaminating produce.
The presence of mice in human habitats can also pose health risks. Mice can spread diseases through their urine and droppings, and they may contaminate food and damage property by gnawing on wood, fabric, and plastic. Therefore, it is essential to take appropriate measures to control mouse infestations and protect both crops and human dwellings.

Mice in fields survive on seeds from native grasses and introduced cereal grains
The house mouse is an omnivore and can live on a wide range of foodstuffs, including most of those eaten by humans. This ability, along with their adaptability to a wide variety of environmental conditions, has earned them their reputation as pests. They are always present under field conditions, usually in low numbers, and have usually been confined to refuge areas where they are not easily detected.
However, a favourable combination of environmental and population factors can lead to a sudden growth in the mouse population. In Australia, mice living under field conditions have a seasonal pattern of breeding. This generally begins in early spring and continues until cold or wet conditions develop in late autumn. Mice can start breeding at just six to ten weeks of age and produce ten to twelve litters per year. The gestation period is 19 to 21 days, with the female re-mating almost immediately after birth.
Mice in fields can cause damage in crop paddocks by digging into loose soil to find larger seeds such as maize, sunflower, wheat, oats, barley, pulses, pumpkin, and marrow. They also eat newly sprouted seedlings before and after they emerge from the soil. In maturing crops of wheat, oats, barley, pulses, sorghum, and maize, losses of up to 30% have been reported.

Mice in food storage areas eat grains, vegetables, meat, fruit, and dairy products
Mice are a common pest in Australia, with the house mouse and field mouse being the most prevalent species. These rodents are highly adaptable and can survive on a wide range of foodstuffs, including most human foods. They are particularly attracted to food storage areas, where they can easily access a variety of foods to satisfy their daily dietary needs.
Mice in food storage areas have a varied diet and will eat grains, vegetables, meat, fruit, and dairy products. They are drawn to high-protein grains and aromatic vegetable oils. In addition to these, they may also consume cereals, fish, bread, biscuits, peanuts, cheese, rolled oats, rice, wheat germ, apples, and melon. Their ability to subsist on a diverse range of foods makes them challenging to eradicate from storage areas.
The house mouse, in particular, is an introduced species to Australia and is commonly found in urban areas. They are highly adaptable and can live off a wide range of foods, including those consumed by humans. Field mice, on the other hand, rarely venture into inhabited buildings but may seek out outhouses and sheds during the winter months to access stored fruit and vegetables.
Mice are opportunistic feeders and will sample all available foodstuffs within their range. They may not return to a particular food source for several days, making it challenging to predict their feeding patterns. Additionally, mice can live and breed without a water source as long as their food provides at least 15% moisture.
The presence of mice in food storage areas poses a risk of contamination and the spread of diseases. They can also cause structural damage by gnawing on wood, fabric, and plastic. Therefore, it is essential to take preventive measures and consult pest control professionals if mice are suspected in food storage areas.

They are particularly attracted to high-protein grains and aromatic vegetable oils
Mice are known to eat a wide range of foods, consuming between 3 and 5 grams daily. In the wild, they survive on the seeds of native grasses and introduced cereal grains. In food storage areas, their diet can include grains, vegetables, meat, fruit, and dairy products.
Mice are particularly attracted to high-protein grains. They are also drawn to aromatic vegetable oils. This attraction to high-protein grains and vegetable oils is likely due to the nutritional content and the energy these foods provide. The protein in the grains helps support their bodily functions and the growth and development of their young. Additionally, the fats in the vegetable oils are a concentrated source of energy, which is essential for their highly active nature and survival.
High-protein grains that mice are attracted to include maize, wheat, oats, barley, pulses, and sunflower seeds. These grains provide a good source of essential amino acids, which are the building blocks of proteins. By consuming these grains, mice obtain the necessary nutrients for tissue repair, immune function, and the production of hormones and enzymes.
Aromatic vegetable oils, such as those with a strong fragrance, are also enticing to mice. Oils derived from plants like sunflower, pumpkin, and marrow seeds possess a distinct aroma that may appeal to the mouse's sense of smell. Additionally, these oils are rich in fatty acids, providing a concentrated form of energy. Mice, being opportunistic foragers, are likely attracted to the energy density that these oils offer.
Understanding the dietary preferences of mice, particularly their attraction to high-protein grains and aromatic vegetable oils, is crucial for effective mouse management and control. This knowledge can inform the selection of appropriate baits and strategies to mitigate the impact of mice on crops, stored food, and human habitation.
