rails, architraves and skirting boards—is taken down and burnt
and the premises thoroughly sprayed with a proved insecticide.
The woodwork is not replaced, but the walls are made good
and a skirting formed with Keen's Cement. One or more
sprayings may be necessary.
Three well-known insecticides have been used, viz.,
Zaldecide, Vermieine, and Concentrated Clensel.
(c) The Council did not in the past year employ Hydrogen
Cyanide Gas in the work of disinfestation, but at the time of
writing such is being used for fumigating furniture of persons
entering Council properties and the disinfestation of empty
properties where necessary.
(d) The work is carried out by Contractors.
(e) The Council now have the services of a very efficient
Housing Manager, who I understand is doing valuable work
by way of supervision and education of the tenants in the fight
against this pest.
(ix) Schools.
The general hygiene and sanitation of the schools throughout
the area is very good and is dealt with in my report on the
School Medical Service on page 62, as also is any action
necessary in relation to the health of the scholars and for
preventing the spread of infectious disease.
