FLY NUISANCE
As anticipated in my last report the spray treatment of vacant lands,
refuse tips, piggeries and stables has been very much extended during the
summer months of the present year by the inclusion of the premises of fishmongers
and butchers. In addition to the vacant lands, including grass
verges, 47 premises were treated by the mobile spraying unit.
This service which is operated at the low annual cost of £150, is welcorned
by the residents in the Borough.
PREVENTION OF DAMAGE BY PESTS ACT, 1949
RODENT CONTROL IN SEWERS
Owing to heavy infestation in certain areas during the year 1951, the
Infestation Control Division of the Ministry of Agriculture and Fisheries
authorised an interim treatment of those areas. This took place in February
when 140 manholes were baited with the following results.
Number showing prebait take 106
Number showing complete prebait take 77
Number showing poison bait take 91
This treatment was considered highly successful and the normal halfyearly
treatments were carried out in the months of May and November with
the following results. I

SURFACE INFESTATION
Rodent infestation above ground, subject to prior investigation by the
Sanitary Inspectors, is dealt with by the Corporation's rodent operative who
carries out treatments at factories, business premises, private dwellings and
properties owned by the local authority. Private dwellings are cleared without
charge but a charge of 5s. per hour is made for this service to factories and
business premises.
The following information is taken from the report furnished to the
Ministry of Agriculture and Fisheries for the year 1952.
