Two old and infirm persons who lived together in an apartment house in the Tokyo area suffered from pediculosis caused by a body louse Pediculus corporis in January 1983. In order to find out where they were infected with the lice, dust samples were collected from 13 bathrooms of community centers for old people located in the same district where they lived, and which they often visited. Adults, eggs and casts of the lice were found in dust samples of two bathrooms. It was supposed that they were infected by the lice in the bathrooms. To control the lice in their house, their clothes and tatami mats were heated at 100℃ in a vehicle which is used to dry mattresses, and then mixed insecticide of fenitrothion and DDVP was sprayed on the floor of their house. No lice were found in the house after the control.
