Beschreibung[en]

This invention relates to a new method of combating insects such as cockroaches or ants at a locus connected to public health, that is to say at a locus frequented by humans, either private or public.

Many insecticidally active compounds are known, such as the insecticidal pyrazoles described in International Patent Publications No. WO 87/03781, WO 93/06089 and WO 94/21606, as well as in European Patent Publications 0295117, 0403300, 0385809, and 0679650, German Patent Publication 19511269 and United States Patents 5,232,940 and 5,236,938. The use of such compounds to kill cockroaches or ants has already been contemplated, but such use was essentially in connection with baits or ingested materials or food that the insect is supposed to eat, or also in connection with direct contact application to the said insects.

The use of baits can be problematic because there is a need to place the baits at a proper locus where the cockroaches are supposed to come. Furthermore the baits can become a safety hazard to children, an undesirable situation.

An object of the instant invention is to provide a method of control of cockroaches or ants avoiding the use of baits or ingestible material.

An object of the instant invention is to provide a method of control of cockroaches or ants avoiding the direct application of the active material to the insect itself, as with baits for example.

The object of the instant invention is to provide a simplified and efficient method of control of cockroaches or ants.

The present invention is thus directed to the use of 1-phenylpyrazole derivatives selected from

5-amino-3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-trifluoromethylsulfinyl pyrazole (hereafter referred to as compound A).

5-amino-3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-trifluoromethylthio pyrazole (hereafter referred to as compound B) and

5-amino-3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-trifluoromethylsulfonyl pyrazole (hereafter referred to as compound C),

in the form of a thin dry layer or embedded in a thin dry layer, which is applied to a surface on which the insect is moving or expected to move, which layer the insect is not able to seize or bite or eat directly,

the surface being selected from glass, ceramics, concrete, plastics surface, metallic or wooden surface, and textiles,

the thin dry layer containing an effective amount of the 1-phenylpyrazole derivative, the effective amount being from 0.01 g to 10 g per 100 square meters

for obtaining lasting control of cockroaches or ants or of a population of cockroaches or ants.

It should be understood that in the instant invention, the active ingredient is rather in the form of a thin layer or imbedded in a thin layer, and that this layer is covering totally or partially the surface where the insect is making contact or is moving or walking or going to walk or expected to be walking or supposed to be walking. Due to this thin layer the insect is not able to seize or bite or eat directly a discrete volume of composition comprising the ingredient of formula (I). This is connected with the unobviousness of the invention.

According to a further aspect of the invention, it provides a method of control of a population of cockroaches or ants able to walk or travel in public or private housing or building or household or home, whereby a non seizable, but insecticidally effective, amount of active ingredient is lying on a surface located in the area to be treated.

According to a further aspect of the invention, it provides a method of control of a population of cockroaches or ants able to walk or travel in public or private housing or building or household or home, whereby a thin layer is covering the surface where the cockroaches or ants are supposed to walk.

According to a further aspect of the invention, it provides a method of control of a population of cockroaches or ants that are able to walk or travel in public or private housing or building or household or home, whereby the said cockroaches or ants are caused to walk on a thin layer covering a surface in or near the area where the said insects are to be killed.

According to a preferred and most efficient embodiment, the invention is applied specifically to cockroaches.

The method of the invention is especially advantageous because it is very easy to apply the active ingredient, preferably by mean of spraying a liquid formulation to the appropriate surface.

The surface which is treated according to the invention may be smooth or rough or rugged. Smooth surfaces are more effective. The surface to be treated is selected from glass, ceramics, concrete ; plastics surface such as vinyl plastics, melamine, linoleum ; metallic or wooden surface such as furniture : textiles such as clothes.

The deposited layer of active ingredient according to the invention may be wet just after application, or may be dried or dry sometime after. The creation of this layer may be made by all known methods of covering, for example as a spray coat, paint, dip, wash, soak, lacquer, foam, dust, powder, aqueous suspension, paste, cream, wettable powder, aerosol, emulsifiable concentrate, concentrated suspension, flowable suspension, aqueous suspension, oil suspension, oil solution, pressure pack, or other standard formulation well known by those skilled in the art.

Compositions comprising an active ingredient of formula (I), especially liquid compositions, have already been described in the here above cited prior art.

Treatment of cockroaches in public health in public housing or building for the control of so-called American cockroaches (Periplaneta americana), but also of other cockroaches like German cockroaches (Platella germanica), is a preferred feature of the instant invention.

The invention accordingly provides a method for controlling cockroaches or ants which comprises applying to a surface with which the cockroaches or ants make contact or are to make contact a compound of formula L The compound is preferably applied as a thin layer.

The preparation of compounds of formula (I) may be performed according to any process described in the here above cited patent applications, or other process according to the knowledge of a person skilled in the art of chemical synthesis.

The effective compositions which may be used in the invention may be offered or presented in different amounts comprising the 1-phenylpyrazole derivative in an amount between 0.01 g and 10 g/100 m2.

The compositions which are useful in the invention (and which are to be spread on surfaces to control cockroaches or ants) comprise generally 0.0001 up to 15 % w/w of active ingredient, preferably from 0.1 to 6 w/w. They may be in the form of a liquid before application, especially in the form of an emulsifiable concentrate, aqueous emulsion, concentrated suspension or flowable suspension. But after drying of the liquid in the form of a thin layer.

The insecticidal compositions may also contain all kind of compatible surface active agent and/or carrier. Adjuvants may also be used, such as sticking agents, dyestuffs, film forming agent or the like. The carrier itself may be solid or liquid.

The compounds of formula (I) may be used in sequence or admixture, particularly admixtures with another pesticide e.g. an insecticide, acaricide or fungicide.

The compositions may be prepared by admixing the ingredients.

The invention is illustrated by the following examples which should not be considered as limiting or restricting the invention.
