Cockroaches: they were not done by people to get rid of these black and red rogues, but the Extermination of such resilient insect still is a problem. Especially for the residents of densely populated high-rise buildings, dormitories and dilapidated “hruschob”. To a very promising means of control of cockroaches is possible, in my opinion, to include electroshock devices, even of the simplest type. I, in particular, has been a “electrovoice” to exterminate an entire Armada Ryuusei insects at the entrance directed to the former owner of the apartment.
Such a well-proven antityrosine the device is assembled on a plate of dried wood. Sizes are based on the purpose and ease of operation. In the hollows out a plaque on the perimeter, with a 15 mm deviation from the edge, the groove width of 4-5 and a depth of 2-3 mm. Along it, at a distance of 0.2 mm from each other, are attached (7-mm nails or with the use of repellent cockroaches do not glue) the inner and outer contours of the electrodes, soldered strips of tin. It is desirable that the formed discharge gap passed over the middle groove.
