Disinfestation methods were applied in all properties where a
report was made that vermin had been located.
Methods employed for freeing infested houses from bugs.
There is no universal remedy for the eradiction of infestation
because of the great adaptability of the bug to difficulties of
environment and breeding, also because its breeding places are so often
well protected and concealed.
When infestation unfortunately occurs certain methods can be
applied which ultimately prove successful provided they are directed
intelligently, and of the various methods, the most reliable is
cleanliness, which will also prevent infestation. The Co-operation of
the householders with the officers of the Public Health Department in
this matter is, therefore, of paramount importance.
Cimex blocks have been used for the generation of gas and
these have been used in conjunction with the use of various insecticides
such as zaldecide, slatford and eradico.
The methods found to be most successful have been the
use of any of the above insecticides applied through powerful sprays,
the woodwork such as the picture mouldings, skirtings, window linings
and door frames and architraves having been loosened or
removed before treatment is applied. The wall paper is afterwards
stripped and a second application of one of the insecticides mentioned
or Cimex is carried out in bad cases.
Occupiers are requested by notices to take down the iron
bedsteads and frames which are treated by means of spraying with
zaldecide etc., and pictures and other articles of furniture in the room
are thoroughly cleansed and sprayed. Afterwards the whole premises
has to be cleansed and purified under notice and supervision of
departmental officers.
No operation can be deemed to be a success without the full
co-operation of the householder and the results of experience prove
that where cleanliness has been established and maintained, the bed
bug can be completely eliminated.
