Grand jury is so named because traditionally it has greater number of jurors than trial jury, called a petit jury (from the French word petit meaning small).
Although mice tend to come out in the night when most of the occupants of the house are asleep or immobile. This allows them to stealthily infiltrate any of your food bags, crumbs etc. During the day time, mice will normally not come out, but if opportunities exist then they surely can.
If you are not constrained to work on the mice at a particular time of day, you may find it easier to work on the mice in the morning to early afternoon. Mice are at their most active just before the lights go out, and are often more difficult to handle late in the day.rasping the mouse by the base of the tail will give you greater control. Tailless mice may be grasped by the scruff of the neck. Relax and handle the mice gently. In most circumstances, if you are relaxed, if the mouse makes an attempt to bite you, it will be a gentle exploratory nibble that will not hurt.
