A wasp blocking device according to the present invention is provided in front of a bee entrance formed open in a beehive main body, and installed to cover the bee entrance formed open in the beehive main body, thus blocking a wasp from entering the beehive main body through the bee entrance or protecting a honeybee that is exposed to the outside and attacked by a wasp. The wasp blocking device is characterized by comprising a wasp blocking mechanism and a wasp obstructing mechanism. The wasp blocking mechanism is composed of: a blocking main body which forms a passage, and in which an end portion on one side is coupled to the beehive body such that an opening portion communicates with the bee entrance and a first blocking part and a third blocking part, which are spaced apart from the end portion coupled to the beehive body, provided in an opening portion on the other side of the blocking main body, and spaced apart from each other in the longitudinal direction of the blocking main body (110) and a second blocking part. The wasp interfering mechanism is composed of: an interfering mechanism base provided in front of the wasp blocking mechanism and a guide passage forming part which is provided in the interfering mechanism base to form a plurality of guide passages.La présente invention concerne un dispositif de blocage de guêpes disposé devant une entrée dabeilles ouverte dans un corps principal de ruche, et installé pour recouvrir lentrée dabeilles ouverte dans le corps principal de ruche, ce qui permet dempêcher une guêpe dentrer dans le corps principal de ruche à travers lentrée dabeilles ou de protéger une abeille qui est exposée de lextérieur et attaquée par une guêpe. Le dispositif de blocage de guêpes est caractérisé en ce quil comprend un mécanisme de blocage de guêpes et un mécanisme dobstruction de guêpes. Le mécanisme de blocage de guêpes comprend : un corps principal de blocage qui forme un passage, et dans lequel une partie extrémité sur un côté est co
