Abstract

The invention relates to a single- or double-sided applicator for administering pest control agents for combating pests, especially insects such as cockroaches and similar. Said applicator has a first sheet (1) with a first surface (2) from which the pests can take up the pest control agents and on which spacers (3) are arranged. Said spacers enable the sheet (1) with the first surface (2) to be fixed at a certain distance from a second surface. According to the inventive method, the pest control agent takes effect slowly enough for the pests to still be able to leave the applicator after having taken up said agent.

Description

Applicator and method for controlling pests, in particular cockroaches

The invention relates, according to the preamble of independent claim 1, to an applicator and a method for the administration of agents for controlling pests, in particular insects such as cockroaches and the like, which has a first plate with a first surface, of which the Pests can absorb the pesticide.

Insect pests, such as cockroaches, moths and the like, can not only be unpleasant in residential areas, they can also cause considerable damage to food supplies, facilities or clothing. They could also wreak havoc as carriers of disease. For these reasons, many inventors have already set themselves the task of controlling such insect pests. The starting point was often to trap the pests and then kill them, especially by using more or less strong poisons.

Cockroaches in particular are insect pests with a pronounced social behavior. If there are already some dead cockroaches in a trap, this place will be avoided by the survivors in the future. Trapping and killing in a trap is therefore not efficient enough in most cases.

Another method of fighting cockroaches is to directly coat the skirting boards or other parts of the wall or furnishings close to the floor with a poison. In the dark, when the cockroaches leave their hiding places, since they prefer to move along walls, they will always hit one of these places and come into contact with the poison. This success However, speaking method has the disadvantage that small children and pets can easily come into contact with the poison, which is why worried parents and pet owners are more likely to shy away from using this method.

The object of the present invention was to propose a device and a method which contribute efficiently to the reduction of the insect pests and which at the same time essentially exclude the direct contact of humans or pets with the agent used to control the pests.

According to the invention - according to a first aspect - an applicator for the administration of agents for controlling pests, in particular insects such as cockroaches and the like, which has a first plate with a first surface from which the pests can take up the control agent, is proposed , which is characterized in that spacers are arranged on this first surface, by means of which the plate having this first surface can be attached or is attached at a distance from a second surface. Preferred configurations of the applicator according to the invention result from the dependent claims.

According to a second aspect of the invention, a method for controlling pests, in particular insects such as cockroaches and the like, with an applicator is proposed, in which a first plate with a first surface, from which the pests can take up a control agent, is attached by means of spacers having fastening means a second surface, for example on a room wall or on a kitchen floor, attached spaced. A third aspect of the invention proposes a method for controlling pests, in particular insects such as cockroaches and the like, with an applicator, in which a first plate with a first surface, from which the pests can take up a control agent, by means of spacers with a second plate and a second surface, from which the pests can take up a control agent and which is directly opposite the first surface, is fastened - placed on a floor or attached to a piece of furniture or a room wall.

Preferred embodiments of the method according to the invention result from the dependent claims.

Advantages of the applicator according to the invention or of the method according to the invention compared to the prior art result on the one hand from the fact that cockroaches in particular can become immune to a certain poison A after about four months of exposure. After this exposure period has expired, the applicators can be removed with agent A and new applicators with another poison B can be placed in their place. The exchange can be quick and easy and, more importantly, it is complete. This means that only one specific poison is used at any time, which can even be monitored by the manufacturer of the applicators. On the other hand, the used applicators can be returned to the manufacturer, so that a complete recycling of the applicators and careful disposal of the poisons can be guaranteed.

Applicators according to the invention are shown in the schematic diagrams below, these are only examples and are in no way intended to limit the scope of the invention. s show:

1A shows a plan view of the first surface of a first plate of an applicator, in accordance with a first arrangement form of the spacers;

1B shows a side view through an applicator with a first plate, according to a first embodiment as a one-sided applicator, corresponding to FIG. 1A;

2A shows a plan view of the first surface of a first plate of an applicator, according to a first arrangement form of the spacers with drawn-in spacers, which were attached to the second side of a second plate;

2B shows a side view through an applicator with a first and a second plate, according to a second embodiment as a double-sided applicator, corresponding to FIG. 2A;

3A shows a plan view of the first surface of a first plate or of the second surface of a second plate of an applicator, according to a second arrangement of the spacers;

3B shows a side view through an applicator manufactured in one piece with a first plate, according to a first embodiment as a one-sided one

Applicator, corresponding to Fig. 3A.

FIG. 1 shows a first preferred embodiment of a one-sided applicator according to the invention with a first plate 1 which has a first surface 2. A corresponding top view (FIG. 1A) shows a first arrangement form of spacers 3. These spacers 3 are at least a distance a away from the edge of the first surface 2 and serve to fasten or position the first plate 1 at a distance d from a second surface (cf. FIG. 1B) . An applicator positioned in this way on a wall - e.g. with double-sided adhesive tape or the like - or on a floor or on any other surface that deviates from the vertical or horizontal is often used by the harmful insects to be controlled, such as cockroaches, moths, etc. Shelter chosen. These pests usually only leave their hiding place to get food after dark. Cockroaches in particular are very shy animals and prefer to seek out narrow hiding places from which they can use their feelers to control the surroundings. The distance a is therefore preferably chosen so that it corresponds at least to the body length of these insect pests. For the cockroach Blattella germanica, which occurs in Switzerland, a distance a of 1 to 5 cm is suitable, with a distance a of 2 cm being particularly preferred. The desired narrowness of the applicator according to the invention, which serves as a shelter, meets - again with regard to the cockroach - a distance d of 2 to 20 mm, a distance d of 5 mm having been found to be particularly suitable. If moths or other insect pests such as silverfish etc. are to be combated, the mass a or d can be adapted to the respective body size of the insect pest.

The entire area of the first surface 2, which is not covered by spacers 3, can be covered with a pesticide in such a way that the pests can absorb this agent. The absorption of the agent can manage the insect actively (food intake) or passively (body care). It is important that the agent works slowly so that the pests only die if possible when they do Have left the hiding place. The dosage, the choice of the poison and / or by offering the poison in microcapsules, which have to be broken open piece by piece by the insect, can influence the effect of the poison in a targeted manner so that the desired delay effect occurs. It is clear from this illustration that the device according to the invention is an applicator for administering the control agent and not a trap in which the insect is to be killed.

In particular, microcapsules are preferably applied by spraying onto the corresponding surfaces 2, 4 of the plates 1, 4. These microcapsules have the advantage that they can only contain small amounts of poison. This means that repeated active or passive absorption by the

Insect pests take place until they have taken a lethal dose. Unintentional poisoning of small children or pets is practically impossible because of this and because the applicators and their surfaces 2, 4 are largely inaccessible.

Two plates, a first plate 1 with a first surface 2 and a second plate 4 with a second surface 5, are preferably manufactured identically. According to a second preferred embodiment of the double-sided applicator, these are glued together (FIG. 2) in such a way that the spacers 3 of the first plate 1 and the spacers 6 of the second plate do not impede one another, but rather an area of the first surface 2 and 2 that is as favorable as possible include the second surface 6 and keep the two plates (1, 4) apart by the distance d. A first preferred form of arrangement of the spacers corresponds to the illustration in FIG. 2A, from which it can be seen that the spacers 3 of the first plate 1 are arranged exactly the same as the spacers 6 of the second plate 4. The applicator was therefore produced by the combination of two absolutely identical panels. It can be seen from FIG. 2B that the two plates, whose first surface 2 and second surface 5 lie opposite one another in the assembled state, are spaced apart from one another by the distance d. 2 therefore shows that all spacers 3, 6 should have the same height d and are arranged at least by the distance a from the edge of the first or second surface 2, 5. The advantage of this design is, on the one hand, that absolutely identical parts can be used, which allows such an applicator to be produced very inexpensively - after all, only two applicators of the first embodiment are combined. On the other hand, a practically open structure of an applicator is created, which allows the insect pests free access to all areas of the first or second surface 2, 5 which are covered with the pesticide.

A second preferred arrangement of the spacers is shown in FIG. 3A: at least two outer spacers 7 and preferably 1 inner spacer 8 are attached at least by the distance a from the edge 9 of the surface 10 covered with the pesticide. The spacers 7, 8 - in the case of use as a simple applicator, according to the first embodiment - have a thickness of d. If the second embodiment is chosen as a double-sided applicator, the thickness of the spacers 7, 8 is still d / 2 or elements that are not identical in construction are used to complete the applicator.

The plates 1,4 and the spacers 3, 6, 7, 8 are preferably made of the same material. The use of cardboard with a thickness of 0.5 to 5 mm has proven itself, with a thickness of 2 mm being preferred. The use of thermoplastics can also be provided. The choice of materials will have to consider the use of renewable raw materials on the one hand and the recyclability of the materials on the other. On the other hand, the use of thermoplastics in extremely humid places can be a decisive advantage. The spacers are preferably glued to the first and second surfaces (FIGS. 1B and 2B). However, they can also be attached to it in some other way or, in particular when thermoplastics or other plastics are used, molded into the plates (FIG. 3B). A one-sided applicator made of thermoplastic plastics advantageously comprises molded-in spacers which have a height d. If identical parts are to be used and the spacers are arranged according to FIG. 3B, a double-sided applicator made of thermoplastic plastics advantageously comprises molded-in spacers with a height of d / 2.

An applicator manufactured in this way can simply be placed on the room floor or, using suitable fastening means, such as double-sided adhesive tape, permanent magnets, clasps or similar means, on any surfaces which are difficult to access for small children and pets, such as room walls behind furniture or in kitchen combinations or on other furnishings. like pictures, mirrors etc. are attached.

Of course, the better the applicators are accessible to the insect pests, the more efficient the control becomes. In the case of fighting moths, the applicators can also be hung freely in a wardrobe, with a string, a hook or the like.

The applicators are particularly suitable for use when only a few or no copies of the corresponding pests have been seen - in other words at the beginning of a pest infestation or for the prevention thereof. On the first and second surfaces are preferred to the Pest control agents attractants which are intended to attract the insect pests to be controlled so that they come into contact with the pesticide.

In a departure from the figures shown, the applicators can have shapes that deviate from the rectangular construction, which also need not be constructed symmetrically. For example, a preferably double-sided applicator against moths is provided in the form of a coat hanger. The application of the procedure is in no way limited to family households; the applicator according to the present invention is also used in guest establishments such as restaurants and hotels or on goods handling sites such as grocery stores, warehouses etc.
