Maintenance Treatment for Rats in Sewers. I am indebted to the
Borough Engineer for the details of the treatment of sewer
infestations which are dealt with by his staff.
The treatments are carried out at six monthly intervals
in April and October, coinciding with an organised campaign throughout
the metropolitan area,. The poisoning mediums used were 2\ per cento
zinc phosphide and 10 per cent, arsenious oxide in sausage rusk
base, together with a preservative, paranitrophenol 0.25 per cento
The table below illustrates the results achieved at these two
treatments.
