Organisation against Mine Pests

The scientific extermination of Rats

Mine-owners know only too
well the serious destruction caused
by rats to timbers and constructional
stock, apart from realising the
nuisance caused by these pests to
miners and colliers, and will no
doubt welcome the movement that
is afoot for the extermination of
the vermin.

Could a modern Pied Piper
be discovered with the magic power
of luring all the rats to their death,
he would save Great Britain and
Ireland the colossal damage caused
to food and property by the rat-
enemy in our midst—which damage
is estimated at at least 40 million
pounds per annum.

The gaunt menace of Jfv’
the rat problem is the more
serious because __________

not only have
we to pay so
huge a price for entertaining the
unwelcome guests, but we also are
faced with the possibility of greater
horrors such as the in troduction of the
germ of Plague which it is definitely
established is carried by rats. Such
possibilities are all the more serious
because of the shortage of medical
men.

Drastic action has now been
taken by the Government, and
undertheRats Orderof August 18th
1918 (No. 1071) local authorities are
empowered to direct the occupier
of land or buildings to take the
necessary steps fortheextermination
of rats. In the event of non-com-
pliance, the local authority itself
will take action and debit the
occupier with the cost.

The only method of extermi-
nation that can be effective in
completely ridding our granaries,

warehouses, shipping, and mills of
these pests, is the introduction into
every rat colony of the disease germ
which is isolated and cultivated by
one of our largest laboratories for
bacteriological research.

These germs or disease-pro-
ducing bacteria are known as the
Liverpool Virus for Rats and Mice,
produced by Evans Sons Lescher &
Webb Limited. It is virulent and
particularly active, and when infec-
tion is introduced amongst a colony
of rats by applying the Virus to
suitable bait, the whole colony is
affected and exterminated, the rats
communicating a fatal intestinal
1^,	disease to one another

and i? most cases
beingspeedily obliter-
ated. The Virus has
110 effect upon human
beings or domestic
animals; and the
disease produced is of a nature that
compels the rats or mice to come
into the open air to die, thus causing
no unpleasant smells.

Liverpool Virus lor Rats is
supplied on bait ready for use in 2/6
and 6/- tins ; for Mice in 1/6 tins.
In this form the Virus involves no
trouble in use ; it can, however, be
obtained without bait if required,
in 2/6 and 8/- tubes for Rats, and
1/6 tubes for Mice.

The Virus is obtainable from
almost all Chemists, but in case of
difficulty write direct to Evans
Sons Lescher & Webb Limited, 56
Hanover Street, Liverpool, who will
supply at the above prices, and will
gladly advise any large users or
institutions on any matter connected
with the extermination of the
rodents. Correspondence as to pro-
cedure in special circumstances is
invited.	<|> c/i
