In all cases of infestation the occupiers were given notice to
eradicate rats from their premises, and in only 4 cases was it found
necessary to have recourse to statutory proceedings under the Act.
Sewer Treatments—1945.
The following is a brief account of the operations carried out
during the year in the baiting of sewers for rodent extermination: —
21.3.45 to 9.4.45.
200 manholes were prebaited for 4 days and poisoned on the
5 th day.
Examination on the 6th day and calculation of poison taken,
according to the formulae of the Ministry of Food, gave an
estimated kill of 1,450 rats.
20.11.45 to 3.12.45.
212 manholes were prebaited for 4 days and poisoned on the
5th day.
Examination on the 6th day and calculation of poison taken,
according to the formulae of the Ministry of Food, gave an
estimated kill of 800 rats.
The unpoisoned prebait used was sausage-rusk, the same material,
mixed with zinc phosphide, being used as the poison bait.
The sewers covered by these operations were within an area
bounded by Riverside, Nightingale Lane, Queen's Road, Sheen Court
Flats, Southern Railway to St. George's Road, Stanmore Gardens, St.
Paul's Road, Pagoda Avenue, Kew Road from Pagoda Avenue to Old
Deer Park Gardens, Evelyn Terrace, Kew Foot Road and the Chertsey
Road.
The results obtained may be considered satisfactory.
