Verminous Houses - Treatment by D.D.T.
On 1st April, 1946, an experimental scheme for the
eradication of bugs in dwelling houses, involving the use of
dichloro-diphenyl-trichlorethane (D.D.T.) was put into operation.
This substance had hitherto been reserved exclusively for use by
the Armed Forces. The work is being observed by officials of
the Ministry of Health.
In addition to D.D.T. in 2and 5$ solutions, a similar
compound known as Gammexane has been used as a disinfestant.
Further, a number of rooms have been treated with D.D.T. and
Gammexane "smokes". In order to estimate the lethal effects of
these preparations, lethane has been used as a "control disinfestant"
in a number of cases.
Actual spraying in connection with the experiment was
suspended on 9th December, 1946, after a total of 4,953 rooms had
been treated in the following manner:-
1,334 rooms treated with 5% D.D.T.
1,164 ,, ,, ,, 2½ D.D.T.
1,196 ,, ,, ,, 0.35% Gammexane.
53 ,, ,, ,, "smokes".
1,206 ,, ,, ,, Lethane.
The work of collating the results, involving re-inspect ions
of the rooms, is now proceeding and until this is finished it is
impossible to arrive at a final conclusion. The preliminary
results indicate, however, that D.D.T. used in a 5% solution
appears to give better results than any other disinfestant used
by the Council in the past. It is hoped to have the final
conclusions by the end of the summer of 1947 .
