The inspection and treatment of sewers was undertaken in collaboration
with the Borough Surveyor. Ten per cent. of the total
manholes in the whole sewer system were test baited, and maintenance
treatment was carried out in these, and other manholes known to be
infested, four times during the year. During 1967, 683 manholes were
baited and only 86 showed evidence of rodent infestation.
The Department continued to deal with rodent treatment and
disinfestation work in Council-owned property within the Borough.
Other Pest Control Work.
During the year 1967, 613 complaints were received concerning
insect pests and the following is a list of the infestations dealt with:—
Ants 23
Bees 26
Beetles 18
Bedbugs 18
Cockroaches 11
Fleas 19
Flies 27
Lice 1
Maggots 9
Mealworms 2
Mites 1
Mosquitoes 20
Silverfish 5
Slugs 1
Snails 1
Spiders 1
Wasps 395
Woodworm 5
Where possible practical help is given by the carrying out of
disinfestation work, but in certain cases reference is made to contractors
who specialise in control work.
The incidence of wasps was again generalised during 1967. No
charge is made for the destruction of nests, but this work can only be
undertaken when the nest is readily accessible. If the number of
requests for assistance exceeds our capabilities, householders are
advised as to the best, and safest, methods of destruction.
Ponds, ditches and other mosquito breeding grounds were sprayed
with insecticide as found necessary, with satisfactory results.
