The invention discloses a wasp breeding method. The method comprises the steps of firstly, in autumn, putting female and male wasps having mating flight into a wasp breeding shed for mating, secondly, keeping the female wasps after mating in a dark place for hibernation, and in the spring of the coming year, putting the individual female wasps after hibernation in nesting boxes for waking, and finally, putting the nesting boxes in the wasp breeding shed so that the female wasps ovulate, and if the emergence number of larvae is 15-20, moving the nesting box to a field farm from the wasp breeding shed for breeding. As a result, the problem that the wild wasp population cannot be applied to the biological breeding field is solved, and the wasp can be well applied to the fields of forestry, crops and fruit trees, and therefore, the wasp breeding has the advantages of improving the yields of the forestry, the crops and the fruit trees while protecting the wasp specie, and also has relatively high direct economic benefit and wide market prospect.
