There has been excellent co-operation from owners and
occupiers of premises where treatments have been carried out.
It is interesting to record that a large number of rat
infestations have been traced to defective frontage drains,
this being the section of drain between the interceptor and the
sewer, and such infestations have been completely eradicated on
reconstruction or repair of the defective drain.
