The invention relates to a trap intended for killing moles by means of the shockwave produced by the explosion of a pyrotechnic charge placed in a strong tube. This tube, located in the tunnel, concentrates the shockwave therein and prevents any expulsion of matter outwards. The state of the firing contact is visible when the trap is in place. The trap consists of a tube 1 containing the charge 2. The rods 5 and 4 transmit the movement of the mole to the contact element 6. The rod 7 carries the other contact element 8. Electrical conductors, immobilized by the peg 9, join the various elements to an electricity source. The simple technology of this trap makes it designed particularly for single use.
