First Bay:—
Bedding, rugs, mats, cushions, curtains, wearing apparel and all
loose material is removed from the house and taken to the disinfecting
station for steam disinfection.
Bedsteads are dismantled, drawers removed from furniture, and
all loose paper removed from back of pictures.
All removable woodwork—skirtings, architraves, etc.—is taken
down and flamed with the blow lamp.
The blow lamp is also applied to holes and cracks in the plaster.
The rooms are then disinfected by burning sulphur (1 lb. for every
200 cubic feet), and is left thoroughly sealed until the next day. (All
brass is smeared with vaseline before disinfection).
Second Day:—
The floor and furniture are thoroughly brushed and dusted, the
contents of the room, the ceiling and walls are sprayed with disinfesting
solution, care being taken to get the fluid into every crack.
The work is carried out by direct labour and the premises are
visited at the expiration of ten days after disinfestation. If the
premises appear to be free from bugs the owner is instructed to replace
skirtings, etc., and distemper walls and whiten ceiling.
The premises are revisited at the expiration of one month and again
after three months.
During the year 178 houses, which have been erected in connection
with Clearance Areas, and to which slum tenants were moved after
their effects were disinfested, were inspected and in 5 cases only slight
re-infestation was found and dealt with.
