Disclosed is a cockroach-trap mainly including a box having a top cover and a bottom tray pivotally hinged together, a metal net spread over inner surfaces of the box and being formed by alternately and densely arranging conductors of different polarities, and an intermittent-high-voltage generating circuit electrically connected to two conductors extended from the metal net. The box is provided with at least one entrance which is not covered by the metal net. When the box is closed, two pin holes separately provided on the top cover and the bottom tray opposite to the hinges together form a socket to receive a plug connected to a power source, so that power can be supplied to the intermittent-high-voltage generating circuit for the circuit to generate intermittent high voltage on the metal net. Cockroaches entering into the closed box can be killed by the high voltage. The cockroach-trap is absolutely safe when the top cover is lifted from the bottom tray and no high voltage current can be supplied to the metal net.
