The invention belongs to the technical field of animal breeding, and particularly relates to an outdoor breeding method for scorpions. The method aims at increasing the yield of the scorpions and improving the quality of the scorpions. A glass enclosure is erected outdoors, and the scorpions grow in the glass enclosure; rubble stacks are erected in the glass enclosure, the scorpions are fed with yellow mealworms, one catty of yellow mealworms is put into each catty of scorpions, a lamp source is arranged in the glass enclosure at night, and various insects are attracted to feed the scorpions; the humidity in the glass enclosure is kept between 45% and 65%, the temperature is kept between 23 DEG C to 35 DEG C, when the humidity is lower than 45%, grass is placed in the glass enclosure, and then water is sprayed to the grass to keep the humidity so that the scorpions can be in contact with the water. According to the method, the natural growing environment is fully simulated, the survival rate of larvae of the scorpions is increased, and the growth death rate of the larvae of the scorpions is reduced.
