Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to new pest repellent compositions and pest repellents.

Conventionally, methods for controlling various sanitary pests such as yellowtail have been known, for example, methods of spraying insecticides such as J-less Ooid thread insecticide, and methods of using various insect traps. These methods kill pests by killing or trapping insects, and can prevent damage such as feeding damage and blood sucking caused by the pests to some extent, but they do not prevent damage caused by insects, such as inside furniture in kitchens, livestock sheds, water sheds, evening baths, etc. It is not possible to avoid the flying, approaching, contact, invasion, contamination, etc. of pests to the human body, agricultural crops, and other animals and plants, and a sufficient exterminating effect cannot be achieved. Moreover, in the above method, it is necessary to treat the pests after killing or catching them, and it is particularly difficult to dispose of pests that die after entering furniture, etc., and is rather a source of contamination. On the other hand, as a pest extermination method that can prevent the above-mentioned pests from flying or invading, and of course does not require any treatment for living or dead, there is a method using a pest repellent, and recently it has a pest repellent effect that can be used in the above method. Various substances are being researched, developed and proposed.

However, none of the various substances proposed above can exhibit a sufficiently satisfactory pest repellent effect, and only a few substances, including N,N-diethyl-mettatoluamide, can be used as sprays, It is only used as a repellent for blood-sucking insect pests such as mosquitoes, snails, pears, and stable flies in the form of 0-shoku, creams, and the like.

In view of the above-mentioned current situation, the present inventors have conducted various studies with the aim of providing a repellent that exhibits an excellent pest repellent effect and can almost certainly prevent the invasion of pests.
