  • Patent number: 6199315
    Abstract: The present an invention can provide effective and excellent flea catching method and apparatus which can attract and catch fleas living in the life space of human beings at a high efficiency without harming the living environment of human beings. The present invention relates to a flea catching method which comprises emitting from a light source light effective for attracting fleas so that the flea catching zone is irradiated with light from the light source in such a manner that even points apart from the end of a catching means at the maximum moving distance made by one leap of a flea have an illuminance effective for attracting fleas, whereby the fleas thus attracted to the light source can be caught by the catching means.
