Regular routine inspections are made of all Parks, Recreation
Grounds and Schools and disinfestation is carried out when
necessary.
Considerable thought has to be given to the right type of poison
to be used, and after much experience it is considered that the most
satisfactory and economical poison to use is that commonly known
as "Warfarin." This poison has the approval of the Ministry of
Agriculture, Fisheries and Food and has the following
advantages:—
It is reasonably safe as far as humans and domestic animals are
concerned, it is not necessary to use pre-baits, therefore the first
baits contain poison and much time is saved.
There are two specific ways that members of the public encourage
rats and mice, to which specific attention should be drawn,
The first of these is the frequent practice of the public in
throwing large quantities of bread out to feed birds. Instances have
been found where large slices of bread have been thrown onto
lawns, these are far too large for birds to consume or carry away
and supply plenty of food for rats and mice. If people desire to
feed birds, the bread should be broken up fine and placed on a bird
table.
The second point is the placing of sheds and chicken houses too
close to the ground, all buildings of this type should be kept at
least nine inches above the ground so as to enable a dog or cat
to get under. Sheds very close to the ground afford comfortable
nesting places for rats and mice.
Treatment of Sewers
The inspection and baiting of sewers is under the supervision
of the Highways Superintendent.
This work is usually carried out at regular intervals on a block
basis, specified areas of the Borough being treated at one time.
Where, however, it is proved that certain house drains are
infested, treatment of the sewers in that area are carried out on
request from this department.
During last year 315 manholes were inspected and treated.
