Abstract

PURPOSE:To provide a cockroach repellent capable of being coated as such or utilized for the treatment of fiber products such as carpets and bedclothes, containing as an active ingredient isobornyl thiocyanoacetate which has been used as a synergist simultaneously used together with a pyrethroid insecticide. CONSTITUTION:A cockroach repellent contains isobornyl thiocyanoacetate as an active ingredient. The cockroach repellent can be employed by directly coating or spraying the repellent on furnitures or floors in a form of an oily agent prepared by dissolving the repellent in a solvent, an emulsion prepared by dispersing the repellent in water containing an emulsifier, an aerosol, etc., or by treating paper, board, cloth, etc., with the repellent and subsequently employing the treated paper, etc., on a passageway for the cockroach or in a cabinet, closet, etc., as a floor material. The repellent may also be employed with the first backing fabric or backing agent for carpets. The repellent can be otherwise used for treatment fiber products such as bedclothes and quilt or mattress bags, etc. The fiber products are treated with the cockroach repellent and simultaneously with a water-soluble or emulsified resin and subsequently dried or heated to provided the fiber products with washing resistance.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a repellent and a repellent method for infesting cockroaches, which are sanitary pests.

Cockroaches are omnivorous insects that live in homes, closets, storerooms, etc., as well as cafeterias, restaurants, and the grocery section of super department stores where food and drinks are handled. It is said to be a fan of sanitary pests because it harbors pathogenic bacteria.

(Conventional technology) Cockroaches are generally called aphids and are widely distributed all over the earth. Cockroaches were originally insects that lived in the tropics and subtropics, but with the development of transportation and heating equipment. Cockroaches are living in J
In addition to this, as food becomes more abundant and the living environment improves, cockroaches have multiplied rapidly, and now they can be found in residential areas, built-up areas, eating areas, hospitals, and other areas.

Many of them were also used in dining cars and sleeping cars in transit agencies. With the proliferation of cockroaches, which are sanitary pests, natural methods for their extermination have been studied.

There are nine different species of cockroaches, but the ones commonly seen are the black cockroach, the Japanese cockroach, and the German cockroach.

Extermination methods are broadly divided into chemical methods and mechanical/physical methods. Chemical methods include spraying insecticides,
Smoking methods, etc. The main mechanical and physical methods are paper box type or glass box type.
Currently, the paper sea bream box type is widely used. The structure is such that a sticky agent is applied to the bottom of the box, bait containing an attractant is placed in the center, and cockroaches17 are guided into the box and captured using adhesive, but neither method reduces the cockroach population. With numbers as low as a few percent or less, there is not much hope for eradication. .

(Problems to be Solved by the Invention) The method of the present invention does not exterminate cockroaches using insecticides, but is a repellent method that is used in areas where cockroaches are not desired to invade.

Cockroaches are very agile and prefer to live in warm, dark places, so they are rarely seen by us during the day. They also have a body shape that allows them to easily pass through very narrow places. Therefore, it is undesirable from a hygienic point of view, as it can enter through small gaps in cupboards etc. and leave feces on the dishes or eat food, oil, etc. Also, it can live in bedding, clothes, etc. that are being stored in the closet. It can also cause damage to certain books.

Directly using insecticides to exterminate cockroaches that have invaded kitchens and other areas in busy households is not a very desirable method.

The most appropriate method is to use repellents that do not allow cockroaches to enter.

(Means for Solving the Problems) The present invention uses isobornylthiocyanoacetate (hereinafter referred to as BTA) as a method for exterminating cockroaches, and has discovered that it has a repellent effect on cockroach traps. devised.

IBTA is a drug used as a synergist in combination with pyrethroid insecticides, but it is not known that IBTA alone has a repellent effect on cockroaches.

The present invention uses IBTA as the main component of a cockroach repellent.
It is what you use.

IBTA can be used in various forms as a cockroach repellent.

For example, oils dissolved in solvents, emulsions dispersed in water by adding emulsifiers, aerosols, etc. can be directly applied or sprayed onto furniture or floors, or after processing paper, boards, cloth, etc. It can be used as a rug for busy areas, cupboards, closets, etc. - It can also be used by blending it into the primary carpet base fabric or backing agent. In addition, it can also be processed into bedding, futon bags, and other textile products.

As a characteristic treatment method of the present invention, when textile products are treated by using a repellent containing IBTA in combination with wash-resistant resins, the repellent effect against cockroaches is maintained even after washing with water or dry cleaning. This is a processing method that leaves behind.
As laundry-resistant resins, IBTA is fixed on the fibers by simply drying after treatment with water-soluble or emulsion resins, or by heat treatment or heat treatment in combination with a catalyst, and is resistant to water washing and dry cleaning. A durable cockroach repellent fiber product can be obtained.

As resins that can be used for washing resistance, various reactive resins such as polyester resins, epoxy resins, alkyl resins, octaalkyl ethylene urea resins and others can be used.

The IBTA of the present invention can be used alone or in combination with a bactericide, a fungicide, a preservative, or the like.

The details will be explained below using examples.

Example 1 A certain amount of the active ingredient of the present invention dissolved in ethyl alcohol was applied to plywood and tested using German cockroaches. The results are shown in the table below.

Test method The test method was followed by the Japan Environmental Health Center.

height? A test sample and an untreated sample cut into IO x 10cII are pasted with double-sided tape into a resin container measuring υ, width -4cs and length 20eII. Place a plywood board (shelter) of the same size on top of the sample with a gap of 3 fins, place damp absorbent cotton and a solid sample in the center, and add petroleum jelly to the inner wall of the container to prevent cockroaches from escaping. After applying 30 adult cockroaches and leaving it overnight, the repellent effect was determined by the number of cockroaches living under the shelter the next morning.

In addition, in order to check for variations in the test, samples were conducted at J-Ren.
