## Abstract

In an apparatus for trapping and killing insects using an electric discharge between electrodes to count and/or kill insects or the like, the present invention presents a technology to almost certainly count and/or kill the insects or the like even when the applied voltage is set low. In an insect-trapping/killing apparatus as an embodiment of the invention, when an insect or the like enters the space between an outer electrode and a central electrode, an electric discharge passes through the insect or the like, whereby the insects or the like is killed. After that, the central electrode is rotated in a preset direction to remove the insect or the like downwards by the frictional force. Since the removing mechanism as described above solves the problem of the clogging of the space between electrodes by the insect or the like, the distance between the electrodes can be set as small as the size of the body of the insect or the like, and the applied voltage can be set accordingly low.

## Claims

### Claim 1

An apparatus for trapping and killing insects, characterized by comprising a pair of rollers disposed parallel to each other with a distance preset according to a size of an insect or the like to be killed; a guiding means for guiding the insect or the like into a space between the pair of rollers; and a roller-driving mechanism for rotating each roller on a central axis thereof, wherein
the insect or the like is pulled into the space between the pair of rollers and squashed thereby when the roller-driving mechanism rotates the pair of rollers in opposite directions.

### Claim 2 (depends on 1)

The apparatus for trapping and killing insects according to claim 1, characterized by comprising an attracting means for attracting the insect or the like and an electric discharging means for generating electric discharge to disabled the insect or the like attracted by the attracting means, wherein
the pair of rollers are disposed on a falling path of the insect or the like disabled by the electric discharging means.
