Predatory mite release bag

The invention relates to a predatory mite release bag, which belongs to the technical field of biological prevention and control, and is characterized in that firstly, the predatory mite release bag is made from paper coated with adhesive layers; secondly, the predatory mite release bag has four sides, among which three sides are flatly sealed by bonding, and the other side is folded inwards and then is sealed by bonding; and thirdly, the side of the predatory mite release bag, which is folded inwards, is provided with a hole during release. Compared with the prior art, the predatory mite release bag has the following advantage that the folded side of the paper bag is hung on a tree trunk by facing the ground, which can prevent rainwater from permeating into the predatory mite release bag and enable predatory mites to be released totally. Because the predatory mite release bag is conglutinated through hot sealing of machines, the predatory mite release bag is convenient for mechanized production.
