House Mouse (Mus musculus)

Meet the house mouse, a mammal that is not only a pest but also a model organism. Did you know that the house mouse comes from Asia, from where, probably travelling with grain shipments, it has spread all over the world?

Mice are small rodents, active primarily at night. They have very sensitive hearing, sense of smell and sight. They eat almost everything they come across, food scraps, various insects, grain and even soap. Mice are found in nature as well as human dwellings, and move often. Besides the damage to food stocks, mice are unpleasant in that they leave their urine and droppings everywhere. They are also dangerous carriers of disease and parasites.

Mice build nests under floors or in attics, and line them with paper, rags, leaves and similar materials. They breed very quickly; females can have up to twelve young, five to ten times per year. Gestation is approximately 20 days. The young are ready to leave the nest in another 20 days, and become sexually mature within their first year. In captivity they can live up to four years. They have many natural predators, like carnivores, snakes and birds.

New Biodiversity Library Exhibition topic – Nature at your home

Wow, have you seen the new BLE topic called „Nature at your home“? This topic gives you an insight on what organisms may be found living near or directly inside your house.


„Nature at your home“ presents more than 20 different species of plants or animals, that have learnt to exploit the benefits of living close to human settlements. You can find them in your garden, as well as directly within your house or flat, sometimes being much closer than you have ever thought. Our new topic, however, also shows that these organisms are also fascinating creatures of the nature. Have you, for example, known that Oriental Cockroach (Blatta orientalis) is able to survive several weeks without its head until it starves to death? Or that the Human Flea (Pulex irritans) posseses the most complex reproductive organs among the animals? If not, then all you need to do is to go through our new topic at the BLE website!

All of the information, pictures and paintings in „Nature at you home“ are linked to their original sources at BHL, EoL or Europeana. Stay tuned!
