Description

  The present invention relates to a recording medium that attracts rodents such as rats by generating ultrasonic waves, a rod attracting device such as rats using the same, a method for inducing the same, and a capture device that uses the recording medium. It relates to things that can detect and attract mice scientifically.

  Conventionally, as a method of extermination of small animals such as mice, a method using a rodenticide or a method of capturing with a mouse trap (see, for example, Patent Document 1 and Patent Document 2). However, these methods are troublesome, have poor capture efficiency, and have insufficient safety considerations.

  In the method using rodenticide, since highly toxic drugs are left unattended, there is a risk that children and pets will accidentally mouth it, and to the environment where other animals eat rats that have been killed by rodenticide. There are problems such as the influence of.

  In the method of capturing with a mouse trap, for example, in a spring-loaded trap, the device is complicated and difficult to install, and the spring's elasticity and repulsive force are strong, so that it may be injured accidentally during installation. Also, if you touch the installed device by mistake, the spring may come off and you may be injured. The most commonly used cage-type mouse trap can only capture one animal at a time, and the trap that captured the mouse once has the smell of a mouse. There are problems such as difficult.

  In the method of capturing the mouse by applying adhesive to a board or cardboard, it is necessary to lay it over a wide area because the mouse can not be captured unless it passes over the adhesive, but only in places where children and pets do not touch it. It cannot be installed and the installation location is limited. Moreover, since the adhesive strength of the pressure-sensitive adhesive significantly decreases when wet with water or oil, there is a problem that it is impossible to capture a mouse with wet feet.

  Furthermore, since these traps are installed aiming at the path of the mouse, the trapping efficiency is poor, and it is very difficult to completely remove the mouse from a predetermined place or range.

  Therefore, in recent years, a method for repelling small animals such as mice using ultrasonic waves has been widely used (see, for example, Patent Document 3 and Patent Document 4). That is, by generating ultrasonic waves having a frequency that avoids rats and the like, mice and the like are prevented from entering the room. According to such a method, since no medicine is used, there is no concern about accidental mouth opening, and there is no environmental impact. In addition, there is no need to install complicated and dangerous devices, and there is no injury due to touch. Furthermore, it can be installed in a place away from the road such as a mouse, and the mouse can be removed from a predetermined range. Due to these features, ultrasonic waves are widely used as a device for preventing the entry of small animals such as mice.

  However, the conventional method for repelling mice and the like with ultrasonic waves has the following problems, for example. That is, there is a problem that the evasive effect gradually weakens due to sound familiarity with mice and the like. In addition, since no repellent effect is produced when ultrasonic waves are not generated, it is necessary to generate ultrasonic waves permanently, and there is a possibility of adversely affecting the human body by continuing to generate ultrasonic waves that rats and others dislike. There was a problem.

  Furthermore, in the repulse method using ultrasonic waves, there is a problem in that it is not possible to capture only by driving away mice and the like, and the number of mice and the like is not reduced, so that it does not lead to a fundamental solution.

  The present invention has been made to solve such a problem, and an ultrasonic sound that can attract a mouse or the like by using an ultrasonic wave used by a rodent such as a mouse for communication.
