Infestation of premises by bed-bugs is still common in
the borough, but it is noticeable that the massive infestations
which were met twenty years ago have disappeared and that
in the majority of cases which now occur only few bugs are
seen. The use of insecticides such as D.D.T. which are not
only effective but have a persisting effect for some weeks
after spraying has been carried out, is probably responsible
for much of the improvement, but the improved standards of
cleanliness amongst the population at large has also had a
considerable effect. The efficiency of the persistent
insecticides has, however, been exaggerated and there have
been many cases where premises have required repeated treatments
over a long period before the infestation could be said
to have been completely eradicated.
