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 con-taincd
in the dust chutes and dustbins, food shops, cafes and canteens,
static water sites, ponds and ditches, etc.
