House mouse Mus domesticus


Originated in the steppes of Central Asia.
Reportedly found in this country as early as the 9th Century, when and how remains unsolved.
Certainly as agricultural practices improved man’s harvests, the need for greater storage facilities were created thus providing more food and nest sites for mice and rats.
