8 stables or piggeries, 10 allotment sites, and one plot of land known
to be particularly bad as a rubbish tip were treated as special sites and
visited on 21 occasions each, particular attention being paid to the manure
receptacles at the stables and piggeries and the compost heaps on the
allotments. Throughout the campaign daily visits were paid to Lewisham
Hospital to spray the refuse container there and also the site of the
kitchen waste bins. 22 visits were also paid to both this Council's and
the London County Council's blocks of flats where dustchutes are
used. 226 dustchutes with 807 openings were sprayed. One private
block containing 9 chutes with 27 openings was also included in this
treatment. The caretakers of this Council's flats were also provided
with sprayers, insecticide and powder, for use in connection with the
containers at the base of the dustchutes, particularly after these had
been cleaned out, and for the sites of the bins used for the storage of
kitchen waste. In addition treatment by spraying was carried out in
10 houses by staff from the disinfecting station following complaints
from the householders concerned. In a number of cases a supply of
insecticide containing 5 percent DDT was also left with the householders
for use in their own sprayers.
Static water tanks and sections of the rivers where the water tends
to become stagnant were sprayed with 5 percent DDT in kerosene
base as an anti-mosquito precaution on 4 occasions.
