Abstract

PURPOSE:To prevent cockroaches from irrupting by coating a food shelf in a kitchen or a superstore, etc., or the interior of a food warehouse and simply repel the cockroaches by spraying a pyrethroid-based insecticide as an aerosol on a wall, a floor, etc., in a room by reducing the amount of the pyrethroid- based insecticide used and applying the insecticide as a repellent against the cockroaches to a coating. CONSTITUTION:This method for repelling cockroaches is to reduce the amount of a pyrethroid-based insecticide used to about 1/10 based on that for insecticidal use and manifest the potency as a repellent against the cockroaches. Furthermore, a synergistic agent, e.g. piperonyl butoxide, N,N-diethyl-3- methylbenzamide, octochlorodipropyl ether, isobornyl thiocyanoacetate or N- octylbicycloheptene dicarboximide is used in combination therewith for enhancing the potency. Thereby, the enhancement of the potency can be expected. The insecticide is blended as a repellent against the cockroaches in a coating or an aerosol for use.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cockroach repellent which is used by adding a drug having a cockroach repellent effect to a paint or an aerosol. It is a method to avoid cockroaches in kitchens in general households, cupboards that store food and tableware, restaurants that provide food, dining rooms or train cafeterias, food counters such as supermarkets, and food warehouses that handle food. .
In addition, vending machines that can easily purchase canned and bottled food and drinks are installed throughout the town. Since these are cooled in summer and warm in winter, the temperature inside the plane is a breeding place because it is a comfortable condition for cockroaches to inhabit throughout the year.

Recently, there have been seen cases in which electrical equipment such as computers and office automation equipment that requires high accuracy malfunctions due to defective insulation, malfunctions of unknown cause, or even fires caused by these. This is due to cockroaches. It seems that there are many other things. If it helps prevent these hygiene problems and equipment breakdowns, it will contribute significantly to society.

2. Description of the Related Art Insecticides have been the mainstream as a controlling agent against hygienic pests in households. Most of the repellents against sanitary pests were against blood-sucking pests, and mosquitoes were the most important target pests. It has been studied for quite some time because it was a vector for malaria parasites. However, no repellents for cockroaches have been studied. As a control agent for cockroaches, organic phosphorus preparations and pyrethroids are all aimed at insecticidal purposes. In addition to this, boric acid-based bait is a poison bait, and no antibacterial agent is expected.

DISCLOSURE OF THE INVENTION The present invention is to prevent the invasion of cockroaches positively by using a repellent unlike the conventional insecticide-controlling agents. Repellents have been used in some parts up to now, but this is for the purpose of repelling blood-sucking insects such as mosquitoes and black flies in the summer, and is applied to exposed parts of the body to prevent blood-sucking. The effective time of is so short that it cannot be applied to anything other than the human body. Further, these repellents cannot be expected to have a repellent effect on cockroaches.

Means for Solving the Problems The present invention, in order to prevent entry of cockroaches in kitchens and cupboards for the purpose of storing tableware and food in a living house, as well as in restaurants, supermarkets, etc. where food is provided, This is to prevent invasion by applying a paint containing a repellent or spraying an aerosol.

As the sanitary pests, in addition to cockroaches, many pests such as mites, mosquitoes, flies, flies, fleas, lice, chafers, helminths, and bedbugs are known. It has decreased considerably. However, this tendency has led to an increase in cockroaches and mites. Cockroaches have become available for breeding throughout the year because the hibernation period has disappeared due to the spread of heating due to the improved living environment.

Many cockroaches carry pathogenic bacteria. Cockroaches are extremely unsanitary pests that can freely enter and leave places that we cannot think of and attach feces to food and drink and tableware. Also, since cockroaches prefer small and easy places, it is very difficult to eradicate them. From this point of view, the most preferable method is to prevent the invasion of cockroaches by applying a repellent.

As repellents, those which have been known for a long time are generally dimethyl phthalate, dibutyl phthalate, diethyl toluamide, 2,3,4,5-bis (Δ ² -butylene) -tetrahydrofurfuraher, and others. Commonly used compounds are MGK Repellent, MGK Repellent 328, Tabtrex and the like.

Other than this, 2,2, -dichloro-3-
(2-Methylpropenylcyclopropane carbonic acid (3-phenoxyphenyl) methyl ester (hereinafter referred to as permethrin) is a low toxicity compound developed as an insecticide, but it is mainly used as a household insecticide. , And found that the amount of permethrin used as an insecticide was about 1/10, which was very effective as a repellent.For this effect, Japanese Patent Application No. 2-75583 (March 27, 1991) was used. Filed in Japanese)

[0023]

The effect of the pyrethroid insecticide as a cockroach repellent was discovered by reducing the amount used for insecticidal purposes. By applying this to paint, it is applied to the cupboards and food cabinets used in the kitchen. Alternatively, it can be applied to the interior coating of food shelves and food warehouses in supermarkets, etc. to prevent the entry of cockroaches. Further, by using an aerosol, it is possible to easily repel cockroaches by spraying it on the wall, floor, etc. in the room, which can greatly contribute to the improvement of eating habits. In addition, it is possible to prevent the cockroaches from contacting by spraying in the vending machine, and it is believed that the cockroaches are caused by the conventional method by blending with the insulating paint such as IC base used in OA equipment including computers. It is possible to prevent unexpected accidents such as malfunctions, failures of unknown cause, and fire accidents.
