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.
Release the mice into tall grasses at least one mile from your house or they will find their way back (no kidding) and the second time around theyâll be wary of your trap and harder to catch. Release them early in the morning so theyâll have a chance to get the lay of the land and build a nest before nightfall.
