Evidence of bed'bug infestation in dwellinghouses continues to
diminish ; spraying with a 5% D.D.T. solution in Kerosene remains
the most economic and effective treatment, and no instance has been
recorded in Richmond of Cimex Lectularius being resistant to D.D.T.
An alternative treatment employing a 5% B.H.C. spray is also available
in cases where D.D.T. is considered undesirable.
The policy of spraying School Kitchens, operating under the
School Meals Service, has been continued and involves one treatment
annually of 5% D.D.T. solution which leaves a residual film of
insecticide on the walls.
The quantity of clothing fumigated before being sent abroad has
increased in recent years ; this service is carried out on behalf of
members of the public to satisfy Post Office regulations, and a small
charge is made for the treatment.
