A novel mouse trap is provided herein. The trap includes a base, a sensing platform having a forward end and a rearward extension and pivotable as a first class lever about an intermediate fulcrum. A spring loaded garrot wire is movable between a spring-load position extending rearwardly of the base and a spring-released, tripped position extending forwardly of the base, holding means for holding the garrot wire in its spring-loaded position and trip bar means for releasing the holding means to allow the garrot wire to move to the spring-released, tripped position. The essence of the invention resides in the provision of a combined holding member and trip bar, of a particular specified shape and having one essential element extending rearwardly from the sensing platform and lying beneath the garrot wire when the garrot wire is in the spring-loaded position. The linkage is pivotal about a fulcrum, and is held to the garrot wire by the holding member. The site of the holding of the garrot wire by the holding member must be outboard of that fulcrum.
