Rodent Control
There is considerable evidence at the present time to the
fact that rats and mice are becoming increasingly resistant to
Warfarin and the Ministry of Agriculture, Fisheries and Food are
doing their utmost to find another suitable poison.
The majority of Local Authorities are reluctant to use
"direct poisons" although this would seem to be the only alternative
unless the Ministry come up with some other adequate bait.
It is important for members of the public to remember that
apart from being a menace to our health, rats and mice eat and
foul food and do a lot of damage to buildings and to service
installations such as sewers and electricity cables, therefore it is
in everybody's interest that we should get rid of these pests.
If householders do not wish to deal with this matter themselves
they should contact this Department where we employ skilled men
who will visit and deal with infestations of rats and mice in
houses or gardens free of charge. It is also important to bear in
mind that rats and mice only flourish if they have access to a
supply of food. Carelessness with food storage or refuse disposal
will encourage rodent infestation. The baiting of sewers is carried
out by the Borough Engineer & Surveyor.

The following is an extract from the Ministry of Agriculture, Fisheries and Food Form I.R.31 — Annual Report on Rats and Mice under the Prevention of Damage by Pests Act, 1949, for the year ending 31st December, 1969.
