The majority of treatment is carried out with a 'Warfarin' bait
which contains 0.025% Warfarin. Warfarin is a poison with
cumulative effect that kills rats, mice and voles painlessly by
causing internal haemorrhage. Rodents become affected after
feeding for three to ten days and no bait shyness or prejudice
is created. When dealing with private property the bait (4—6oz
for rats, 9oz. for mice and voles) is placed on a bait tray and
protected from other animals and from the elements. The bait is
inspected daily and replenished where necessary. Untouched
bait is moved to more favourable places or to points where heavy
feeding has taken place. Householders are advised as to the
necessary precautions to prevent access to the bait by children
or animals, particularly cats and dogs. If a human being had
accidently eaten Warfarin bait, a heaped teaspoonful of salt in
a glass of warm water should be given and repeated until the
stomach has been emptied by vomiting and medical treatment
obtained.
The department is represented on the London No.l (Northern)
Pest Control Committee and the No.2 (Essex) Workable Area
Committee.
Routine baiting of sewers is carried out on a contractual
basis under the control of the Acting Borough Engineer & Surveyor.
