DESTRUCTION OF INSECT PESTS IN THE HOME.
Bugs: During the year 75 houses, involving 126 rooms,
were treated by the Department for the destruction of bed
bugs. The treatment consisted of spraying the walls, furniture
and bedsteads with a 5% solution of D.D.T. in kerosene.
Respraying, particularly after redecoration of the rooms is
effective in preventing a recurrence.
Cockroaches: 5% and 10% D.D.T. Powder has had a
marked effect in eradicating these pests from properties and
in addition the product "Gammaxane" has been added to
the Department's list of lethal powders and is giving even
better results than D.D.T.
Flies: In August all pig bins, together with the ground
and wall surfaces in their immediate vicinity were sprayed
with 5% D.D.T. in kerosene. It was hoped that flies attracted
by the pig food would be destroyed in this way.
The results appear to be very satisfactory and it is now
proposed to make this a regular feature of the summer programme
until such time as the necessity for the pig bin ceases.
