There are also other spring-style model traps that kill the animals via a sharp spike. The basic concept is the same, but instead of clamping down on the animal, these traps stab them in a lethal way once triggered. This should also kill the animal instantly without undue suffering.

There’s also another type of mole trap known as the half-barrel or Duffus trap. These are commonly used by professionals because they’re so effective. The basic design features a half-barrel made of metal which contains two separate triggers and wire loops designed to capture and suffocate moles. When a mole touches one of the triggers of this trap, the wire loop instantly tightens very strongly around the animal. The big advantages of this trap are that it’s easy to set and can catch two moles in the same trap.
