Harris mouse glue traps are an easy to use, non-toxic solution for control of mice. There are no springs to set and no snapped fingers. Rodents are attracted to these pre-baited traps where they are caught by a strong adhesive. Directions: Place the traps lengthwise along walls and baseboards where rodents like to travel. Place the traps in areas where there is evidence of rodent activity. If, after several days, no rodents are caught, move the traps to another location. Best results are achieved using more than one trap at a time. Discard rodents and traps. Do not use the traps in wet areas. In case of accidental contact with the adhesive, use baby oil or cooking oil for cleanup. Do not place traps where they may come into contact with birds and non-target animals.
