Baiting of Sewers
In 1955 the Ministry of Agriculture, Fisheries and Food Infestation Control Division

in the Borough since 1951. In consequence, in 1956 the Council again undertook the work
of rodent repression in sewers. Two treatments were carried out during the year using
sausage rusk plus 2½% zinc phosphide, with the following results:—
