Anti-Fly and Anti-Mosquito Campaign.—During the summer
period, April to September, the campaign has continued on
similar lines to previous years. Three men are employed in this
important preventive aspect of the Department's work consisting
of dealing with complaints and carrying out routine inspection and
treatment of sites where breeding may occur. A motor cycle with
a box sidecar is used to convey personnel and the necessary
appliances and materials.
The major factors to be controlled include house refuse
contained in the dust chutes and dustbins, food shops, cafes and
canteens, static water sites, ponds and ditches, etc.
The treatment of house refuse in the dustbins was carried out
by arrangement with the Borough Engineer, a small quantity of
'Gammexane' powder being sprinkled into the dustbins at each
weekly collection. The dust chutes in the numerous blocks of flats
received regular treatment with 'Gammexane' powder by anti-fly
personnel, as soon as possible after dust collection.
Static water sites, ditches, etc., were sprayed with either D.D.T.
in Kerosene or Malariol, and in certain instances dusted with
'Gammexane' powder.
Vacant and bombed sites are regularly inspected for offensive
deposits in the nature of dead animals and food waste. It is found
that these items are generally placed away from the public view
and can become a potent source of fly breeding if not detected.
Other deposits include mattresses, discarded clothing and sundry
items of furniture, etc, surreptitiously dumped on vacant spaces
because the public, in the main, are unaware that this authority will,
upon request, collect and destroy such articles.
Deposits which by reason of organic substance allow fly
breeding are sprayed and removed for destruction centrally and the
immediate area sprayed and subjected to follow up inspection
Other items are either treated and disposed of centrally, or burned
on the spot
Disinfestation of Verminous Premises.—D.D.T. in kerosene
continues to give good results in dealing with verminous premises
when alternated with other vermicides to counteract the development
of organismal resistance.
