Developed and provided is a method of collecting a large amount of high-quality bagworm silk threads having no contaminant from bagworm nests in a convenient manner and at low cost. The habit of bagworms is utilized to allow a bagworm to build a nest using solvent-soluble substances or thermally meltable substances as nest materials, followed by dissolving or melting the nest materials to separate the nest material from the bagworm silk threads, whereby only pure bagworm silk threads constituting the bagworm nest can be obtained.
