Abstract
A rodenticidal composition comprises a toxicant and an emulsified fatty carrier. The carrier preferably comprises a mixture of water soluble fats or fatty oils, particularly a mixture of palm and soya oil. The toxicant may be for example coumarin derivatives, chlorinated hydrocarbons, heterocyclic derivatives or naturally occurring compounds. The composition may be applied to non-horizontal and non-flat surfaces of rodent runways, suitably on an adhesive tape set down on the surface to be treated. The composition is preferably applied by an applicator which has a through bore connected at one end to the neck of a container and opening at the other end, to a recess extending to the periphery of the applicator. The recess has side walls such that, as the composition leaves the bore and the applicator is moved relative to the surface, the composition is applied in the form of a strip. <IMAGE>
Description
SPECIFICATION Rodenticidal composition
The present invention relates to a new composi
tion for controlling rodents; and to a method and
apparatus for applying same.
It is known to control the size of the rodent popula
tion by the use of rodenticides in a number of differ
entformulations. For example the rodenticides may
be mixed with solid food, such as oatmeal or wheat
to form a poisoned bait. Alternatively the rodenticide jnay be mixed with a carrier dust, and placed in 'patches along a rodent runway. In this case the ani .mal picks the dust up on its feet, tail and fur, from
where the toxicant is ingested into the rodent's body
when it grooms itself. A solid dye material may be
added to the toxicant/carrier dust mixture so that the
tracks of animals that have picked up the dust will
clearly stand out against the background.
As an alternative to a visible dye a dye that
absorbs in the UV region and fluoresces in the vis
ible may be used, as outlined in UK Patent Applica
tion 2,002,634A.
There are numerous disadvantages in using for
mulations of the above mentioned type.
1. Such formulations cannot readily be placed on
surfaces that are not substantially horizontal and flat.
It follows that it is very difficult to place such pellet
bait or contact dust along rodent runways that
traverse for example vertical surfaces, pipes, ducts
or chases.
2. Even if placed on substantially flat surfaces, dusts
especially, tend to be blown from their original posi
tion by draughts or the wind.
3. The tendency of dusts to be blown from their orig
inal position leads to difficulties in their removal
after use, and thereby, because of incomplete
removal, to contamination of the environment.
It is the aim of the present invention to provide a
rodenticidal composition which may readily be
applied to non-horizontal surfaces and/or may sub
sequently be removed leaving minimal residual con
tamination.
According to the present invention there is pro
vided a rodenticidal composition comprising a
toxicant and an emulsified fatty carrier. The emul
sified fatty carrier may comprise an emulsified mix ture of one or more water insoluble fats or fatty oils
of vegetable or animal origin such as those com
mercially available as edible spreads.
The fats or fatty oils are predominantly glyceryl
esters of fatty acids, or triglycerides, as described in
more detail in Kirk-Othmer, "Encyclopedia of Chem
ical Technology", 2nd Edn., 8th Volume, pp 776-811.
Preferably the fatty oils of this invention are veget
able oils, for example almond, apricot, kernal, corn,
cottonseed, kapok, olive, palm, peanut, poppyseed,
rice bran, safflower, sesame, soya, sunflower seed,
or teaseed oil. The water emulsions may be stabil
ised by any of the emulsion stabilisers well known in
the fat or fatty oil art. For example monoglycerides, mixtures of mono-, di- and triglycerides or phos
phatides may be used.
Other conventional additives such as antioxidants may be included. A particularly convenient carrier is an edible spread based on a mixture of palm and soya oil.
Preferably the mixture of fats or fatty oils comprises at least 25% by weight, especially 40-60%, of linoleic acid esters.
The toxicant of this invention may be any of the rodenticides that have found use in the rodenticidal art. For example coumarin derivatives, such as brodifacoum or difenacoum, chlorinated hydrocarbons, such as zhexaciliorocyclohexal1e, complex heterocycles, such as norbromide, or naturally occurring compounds, such as calciferol (Vitamin
D2), have been used successfully in the rodenticidal composition of this invention.
The concentration of toxicant in the composition will depend upon the toxicant employed. Generally, in order to be effective against rodents, lower concentrations of coumarin or naturally occurring toxicants are required than their chlorinated hydrocarbon or complex heterocyclic counterparts. Typically coumarin or naturally occuring toxicants comprise less than about 2% (wt/wt) of the rodenticidal composition whilst chlorinated hydrocarbon or complex heterocyclic toxicants comprise between about 5 and 20% (wt/wt) of the composition.
In addition to the toxicant and fat or fatty oil, the rodentidical composition of the present invention may additionally comprise one or more dye components that absorb either in the visible region of the electromagnetic spectrum or in the UV region, or both. Any of the dyes that have found use in the rodenticidal art may be chosen but a particularly preferred dye, which absorbs both in the visible and UV regions, is a red fluoresing melamine formaldehyde sulphonamide pigment, sold under the Trade Names "Fire Orange" or"Saturn Yellow" and as supplied by Messrs. Swada (London) Ltd in the "E" or "MF" series. Typically the dye may comprise between about 2 and 7%, preferably 3 and 5% (by weight) of the composition.
By using a dye, visible or UV absorbing or both, it is possible, by using the present composition, not only to kill the rodents that pick up the composition but also to identify the runways of the animals, as explained in UK Patent Application No. 2,002,634A.
In a further aspect of this invention of this invention there is provided a method for the control of rodent populations wherein the rodenticidal composition of the present invention is applied to the surface of known or suspected rodent run-ways or other areas to which rodents have access. In a preferred embodiment of the method of this invention a strip of adhesive tape or such like is applied, adhesive side down, to the surface and then the rodenticidal composition of the present invention is applied along the non-adhesive side of the tape. The advantage of using such tape over the direct application of the composition to the normal surface lies in the ease by which, after the rodent control treatment has ended, the rodenticidal composition may be removed simply by peeling the adhesive tape from the surface.
In further embodiments of the method of this invention either the rodenticidal composition of this invention is applied to stiff paper, card or such material, which is then folded into a cone, half cone or similar shape and inserted into the mouth of a rodent's burrow or the composition is applied along the run-way portion of an ordinary bait container, the hopper of said container enclosing plain unpoisoned food such as wheat or oatmeal.
Generally the advantages of the composition of this invention and the methods of application thereof lies in the ability of the present composition to be applied to non-horizontal and flat surfaces, such as pipes, ducts, chases and walls, upon which it is difficult to place dusts or pellets. Further the present composition, once applied, will not fall off a surface or be blown from its original position so that it is easier, once used, to remove than dusts and pellets and is consequently less likely to contaminate the environment than these earlier rodenticides.
Rodents are generally killed by the composition of this invention in the same way as they are killed by contact rodenticidal preparations in dust form, that is as a result of grooming themselves. However it is an additional advantage of the present composition that rodents appear two favour fats orfatty oils, especially vegetable fats or oils, as food substances, and that therefore many of them ingestthetoxicant not only during grooming but also during feeding.
The rodenticidal composition of the present invention may be applied to run-ways etc. by or from any suitable applicator, for example the composition
may be applied by a spatula to the runway or may be
squeezed from a tube, in a manner similarto the
application of toothpaste to a brush, however a particularly suitable device for applying the rodenticidal
composition of the present invention comprises an
applicator having a through bore adapted to be con
nected at one end, either directly or indirectly, to a
reservoir containing the rodenticidal composition and opening, at the other end, onto a recess of known depth extending to the periphery of the applicator, said recess having side walls which are so arranged that, as the composition leaves the bore and the applicator is moved relative to and in contact with the surface, the composition is applied in the form of a strip.
Preferably the reservoir is a flexible container of plastic or metal construction, with a threaded neck.
In such a preferred embodiment, the bore of the applicator is also threaded allowing the applicator to
be screwed onto the neck of the container. When not
in use a suitable threaded cap may be screwed onto the container in place of the applicator.
The applicator, which preferably comprises either
plastic or metal, may be of any convenient shape. In one preferred embodiment the applicator is cylindri
cal, with the bore, in a substantially central position, opening onto the two parallel flat surfaces of the cylinder. The recess, which is formed by moulding or
by milling one of the parallel flat surfaces ofthe cylindrical applicator, may extend only from the bore to the periphery of the flat surface or it may extend from behind the bore to the periphery. It may even
extend diametricaliy across the whole of one flat surface. It is preferred however that the recess extends to one side only of the periphery. The recess may be of any suitable depth or width.In a preferred embodiment of the apparatus of this invention the dimensions of the recess are such that, in use when normal pressure is applied to the container, it produces a strip of rodenticidal composition of about 2cm. wide and 1 mm deep.
Adhesive tape may be provided for use in conjunction with the applicator as outlined above.
The rodenticidal composition, the method of application of said composition and the appratus for performing said method will now be described by way of Example only with particular reference to the
Figure, wherein Figure 1 is a perspective view of gne embodiment of the applicator and container of the apparatus ofthis invention.
Referring to the Figure a flexible plastic container 1, containing a rodenticidal composition of this invention, has a threaded neck 2 with an opening 3 through which the compositiion may be expelled. A plastic cylindrical applicator 4 has a threaded through bore 5, the thread of which compliments the thread of the container's neck. The bore 5 opens centrally onto the two parallel flat surfaces of the applicator 4. The surface adjacent the container is plane whilst the other 6 has a U shaped recess 7 of uniform depth that extends from the periphery 8 of the surface 6 to a position 9 behind the bore 5. The recess 7 is surrounded by parallel side walls 10 and arc shaped back wall 11.
In an alternative embodiment either or both the container 1 and the applicator 4 may be of metal construction. Further the neck 2 of the container 1
may be plane and compliment a plane through bore
5 in the applicator 4.
In use the applicator 4 is screwed onto the neck 2 of the container 1 with its recessed surface 6 facing away from the container 1. A strip of adhesive tape (not shown) is laid on the surface to be treated and then the container 1 is positioned perpendicular to the tape and surface such that the recessed surface 6 of the applicator 4 lies on the tape. The rodenticidal composition is then expelled from the opening 3 in the neck 2 of the container 1 and therefrom through the bore 5 of the applicator 4 by the application of pressure to the flexible container 1. As the composition is expelled the container 1 is moved along the tape ensuring that the periphery 8 of the recessed surface 6 forms the back edge of the applicator as it is moved, and that the container 1 is retained in a perpendicular relationship to the tape. In this waya strip of rodenticidal composition may be applied to the tape. The width and depth of the strip will
depend on respectively the width and depth of th; recess 7, the pressure applied to the container 1 and the speed with which the container 1 is moved along the tape. When the application of rodenticidal com
position has been completed the applicator 4 may be screwed off the neck 2 of the container and be
replaced by a threaded or plane cap (not shown) that
also compliments the neck 2 of the container 1.
The following rodenticidal compositions were
prepared by mixing the rodenticide and the sul
phonamide pigment into the vegetable fat until the
toxicant and pigment were each evenly distributed
throughout the carrier.
