Two treatments of the sewers were carried out during the year on lines agreed
with the Infestation Division of the Ministry of Agriculture, Fisheries and Food
The results once again demonstrated that six-monthly treatments merely hold the
rat population of the sewers in check and that to make any marked reduction, more
frequent treatments are necessary (three, or possibly, four a year) using new poisons
as they become available.
In a closely built-up area such as Fulham, the source of practically all
infestations by rats is from the resident population of the sewers, and any reduction
in this source should result in a reduction in surface infestation.
Mice infestations were found to be mostly of a minor character and in some cases
are recurrent.
