Open the sticky mouse board, there is a layer of strong mucus on it, and at the same time disperse some of the food that the mouse likes to eat. Place it in a place where rats often infest (one or several). The rats forage for food at night, and can’t wait to eat when they smell far away. As soon as they touch the sticky mouse board, they immediately act like flies and sticky fly paper. Can’t escape anymore until found. Remove the mouse from the sticky mouse board, remove the dust and continue to use it to capture the mouse.
