Baiting of Sewers.
No rodent repression work in sewers was carried out during the year by the Council
owing to experiments in sewer maintenance treatments which were undertaken by the
Ministry of Agriculture and Fisheries Infestation Control Division. The treatments have
been carried out at three-monthly intervals since October, 1951, and have consisted of
direct poison baiting using 1% by weight sodium monofluoroacetate in damp sausage rusk.
The Ministry have kindly supplied the following summary of the results obtained during
the past year:—
