Rodent Control in Sewers
A new system of rodent control in sewers recommended
by the Ministry of Agriculture, Fisheries and Food with
the use of fluoracetamide as a direct poison bait was
carried out in five areas of the Borough in March and
October. Maintenance treatments had previously been made
with warfarin, a system which entails at least three
visits to every manhole treated. The use of fluoracetamide
is very much simpler than warfarin as only one visit
to each manhole is required with a consequent saving of
labour and transport. It does however mean that with the
use of fluoracetamide no direct evidence is available at
the time as to the efficiency with which the system
operates. It was however, proposed to carry out a further
full scale treatment with warfarin in 1962 as a control
measure. Persistent maintenance treatments of the sewers
in the Borough have now been carried out over a very long
period with increasingly satisfactory results so far.
