Pest Guide: Mice.

The two most common mouse species in Sweden are the house mouse and the forest mouse. A house mouse is about 9 cm long with an equally long tail and has a gray-brown coat that often changes to yellow-brown. A forest mouse can be both smaller and larger than a house mouse and is characterized by their yellow-brown color on the back which often changes to reddish brown. The wood mouse has larger eyes and ears compared to house mice and their droppings are shorter and thicker.

Mice reside in walls, cavities and under larger equipment, storage spaces and furniture. They are omnivorous, but seeds and grains are at the top of the food list. In this guide we will go through why it is important to fight mice, give you tips on how to detect mice and what you can do for prevention to keep the mice away.

 

Why fight mice?

Mice can get through minimal nooks and crannies and it happens that they build nests where there are electrical cables and then the consequences can be very serious. They can damage most materials and objects through their sharp teeth.

But above all, mice can spread infections such as salmonella and sork fever through their droppings. As mice reproduce very quickly, it is important to discover as soon as possible that you have a mouse problem and take action.

• Tracks - on dustier surfaces or with the help of tracing powder. There may also be traces of living material
• Rubbing marks - their fur is oily, which means that you see rubbing marks on surfaces or objects
