Identifying Mice

Mice are nocturnal creatures and are rarely seen by homeowners. This can make the job of identification quite difficult.

They often forage for food at night or during dusk, when most of the other residents of the house are asleep. Even if homeowners do catch a sight of their mouse invader, it may only be for a split second and not enough to identify the species.
