Description

  The present invention relates to a repellent for repelling small animals such as mice, and more particularly to a repellent having a soil reducing property that is decomposed by the action of microorganisms and the like.

  Small animals (hereinafter referred to as “small animals”) such as mice, hakubishin, weasel, raccoon dogs, and cockroaches often transmit pathogenic bacteria and are harmful to human life. The damage caused by small animals, such as the disconnection of wiring in office buildings and ordinary households by small animals and the occurrence of fires and power outages associated with them, has been a serious social problem, especially restaurants that cook food, factories that process food Since small animals may cause pathogenic bacteria and cause food poisoning, it is important to eliminate small animals in terms of hygiene management. In addition, it is said that the source of infection of severe acute respiratory syndrome (SARS) is hackubicin, and it is important for human life to eliminate small animals.

  As a method for exterminating such small animals, for example, there is a method of spraying an insecticide or the like. However, small animal carcasses had to be treated after spraying with insecticides and the hygiene problem was not solved. In addition, drugs that are components of insecticides are toxic to humans and have a problem with safety.

In order to solve these problems, for example, Patent Document 1 proposes a repellent using a herbal medicine with low toxicity to humans. However, when the repellent is buried in the soil, the repellent remains in the soil as it is without being decomposed by microorganisms or the like, and there is a possibility that the environment may be destroyed. Accordingly, there has been a craving for the development of a repellent that is gradually decomposed by the action of microorganisms or the like, that is, that reduces the soil, while maintaining the repellent effect of small animals.

  This invention is made | formed in view of the above situations, and it aims at providing the repellent which carries out soil reduction | restoration.

  The above object of the present invention is effectively achieved by containing a small animal repellent active ingredient, beef tallow, fatty acid, hydrogenated oil, surfactant and pigment.

  The above object of the present invention is that the small animal repellent active ingredient is wood vinegar, or the small animal repellent active ingredient is mint oil, or the small animal repellent active ingredient is capsaicin. Alternatively, it can be more effectively achieved by containing at least one of charcoal, diatomaceous earth, and calcium carbonate.

  According to the small animal repellent of the present invention, small animals can be effectively repelled by containing small animal repellent active ingredients such as wood vinegar, peppermint oil, capsaicin and the like. In addition, since the small animal repellent of the present invention is decomposed and reduced by the action of microorganisms and the like, it is possible to effectively repel small animals without destroying the environment.

  In addition, small animal repellent active ingredients such as wood vinegar, peppermint oil and capsaicin have low toxicity to humans, and therefore it is possible to safely repel small animals.

  Furthermore, the small animal repellent of the present invention can be used as a crayon, and an excellent small animal repellent having both functions as a repellent and a crayon can be provided.

  The small animal repellent of the present invention comprises a small animal repellent active ingredient comprising wood vinegar, peppermint oil and capsaicin, beef tallow, fatty acid, hydrogenated oil, surfactant and pigment.

  Hereinafter, the small animal repellent of the present invention will be described in detail.

  The small animal repellent active ingredient used in the small animal repellent of the present invention refers to wood vinegar, mint oil and capsaicin. As a result of the inventor's diligent research, small animals have found out that they dislike the smell and taste of wood vinegar, peppermint oil and capsaicin, and have developed the present invention. Wood vinegar, peppermint oil and capsaicin can be used as they are on the market, and capsaicin may be used in powder form. In addition, when using capsaicin as a small animal repellent active ingredient, you may use a pepper in powdery form. A plurality of these may be used in combination.
