The invention discloses a plastic film disinfectant for centipede culture and relates to the technical field of centipede culture. The plastic film disinfectant is prepared from the following raw materials in parts by weight: 10-15 parts of toona sinensis leaves, 5-10 parts of folium eucalypti robustae, 4-8 parts of lawn pennywort herb, 3-6 parts of coix seed powder, 3-6 parts of macroporous adsorption resin, 3-6 parts of herba verbenae, 2-4 parts of activated clay, 2-4 parts of nettle leaf, 2-4 parts of buckwheat flour, 1-2 parts of bamboo juice, 1-2 parts of polyoxyethylene, 1-2 parts of lanolin alcohol, 1-2 parts of corn pollen, 0.5-1 part of turpentine, 0.5-1 part of resina liquidambaris, 0.5-1 part of spina gleditsiae, 0.5-1 part of hydrogenated palm oil, 10-15 parts of glutinous rice wine and 100-150 parts of water. The plastic film disinfectant has a disinfection effect while cleaning plastic films, so that healthy growth of centipedes is prevented from being affected by residues attached to the films; besides, the disinfection effect is remarkable, and the acting time of the disinfectant is prolonged under the combined action of the macroporous adsorption resin and the activated clay.
