Visiting the complex with self-trained entomologist Charles Pomerantz, the two peeled back wallpaper to find the walls swarming with mites, so much so that tenants had described that "the walls had movement". Huebner's investigations on the site led to the conclusion that tenants had been bitten by a mite identified as "Allodermanyssus sanguineus", found on mice that infested the storerooms and incinerator areas in the buildings. After culturing and isolating the organism in laboratory mice, the pathogen they named "Rickettsia akari" was identified as the ultimate cause of the disease now called rickettsialpox. The Department of Health announced a program to work with building owners to exterminate the mice that were the vector for the disease.
