Disinfestation of Verminous Premises.—D.D.T. in
kerosene has been used as a vermicidal agent in dealing with
verminous houses and has been proved to be most effective; it
has rarely been found necessary to give second treatments.
During the year the Sanitary Inspectors dealt with 174 cases
of dirty and verminous houses, compared with 246 for 1949. The
Disinfestation staff sprayed 448 rooms and contents as compared
with 938 last year.
In 32 cases the bedding and effects were removed to the Council's
Disinfecting Station for steam disinfection and 46 houses were
treated for infestation by other pests such as cockroaches, ants,
moths and wasps.
