    Critical insights relating to the distribution, natural history, and abundance of Ptinidae sensu lato, in Wisconsin and North America have been overlooked in many faunistic surveys and taxonomic studies, in part due to the relative difficulty in working with the contractile nature of many species and complexity of certain taxonomic characters. Work by H.C. Fall, R.E. White, and T.K. Philips significantly aided in the understanding of this family, although numerous genera are still in need of major revision. This study is the first state-wide survey of Wisconsin Ptinidae. It provides a comprehensive list of all ptinid species documented from Wisconsin, with taxonomic keys for their identification. Profiles for each species were compiled, including a taxonomic overview, capsule description, species diagnosis, and overview of their natural history. Specimens were collected using a variety of methods during two field seasons; Lindgren funnel traps and flight intercept traps were particularly significant. Trap samples from previous faunistic surveys of other taxa and mounted specimens from private and public research collections were also examined. Seventy-eight Wisconsin pest control companies and the University of Wisconsin insect diagnostic laboratory were consulted for information regarding indoor pest species of Ptinidae. During this survey, 28 genera and 64 species of Ptinidae were documented from the state from 2,063 specimens. Of these, 14 genera and 46 species are considered new state records, a 72% increase from the number of species known previously.
