atomised D.D.T. spray blown from a compressor carried on the
back of a jeep. This method was suggested as ideal for the treatment
of refuse dumps and houses and it was felt that it might considerably
help our problem in connection with bombed sites, etc.
While the actual demonstration was impressive, it was felt that
for an area like this Borough, sufficient control could be attained
by the use of materials and methods at our disposal and that we
would not be justified in recommending the expense of the other
installation to the Committee.
It should be added that in the case of one house treated by the
installation referred to the tenants volunteered the statement later
that " the hand spraying by your employees was a greater success."
Another point that I might mention in this connection is that
though the demonstrators suggested to Mr. Collins (Senior Sanitary
Inspector) that the Council's Depots and refuse disposal might be
good testing grounds, when they visited the Depots for that purpose,
they admitted to the Inspector that there was nothing for them to
demonstrate on.
One other important element in the scheme was the difficulty
experienced in controlling Fly breeding in blocks of flats where
dustshutes are the method of immediate disposal of house refuse.
It was considered dangerous to use D.D.T. spray because of possible
fire. During the month of August and to the closure of the scheme,
these dustshutes in the flats (over 100) were treated fortnightly by
the Anti-Fly Squad with marked success.
The Committee will recollect that the anticipated cost of the
scheme was estimated to be in the region of £1,000 to cover materials
and men employed. At the end of the period, approximately £800
had been spent and tabulated below is a brief schedule of the work
carried out within the figure mentioned.
