To ensure animals are dispatched quickly and humanely, all approved spring traps have been tested to assure that they exceed  threshold mechanical characteristics in terms of effective mass, velocity, impact force and clamping action.

The following examples illustrate the diversity of designs available.

Kania 2000

This example imported from Canada, comprises a metal box enclosure with a front access opening and a rear bait compartment.  It incorporates a large torsion spring coiled about an axis normal to the front entrance and having tangentially extending free end arms.  One arm for setting and the other arm being the striking bar.

This trap provides a high degree of certainty of killing and a high degree of safety for the trapper when setting.

All spring traps used in the UK must be approved under The Spring Traps Approval Act.

A list of spring traps approved as being suitable for grey squirrels can be viewed on the DEFRA website.

Beware of copies which may not be approved for use in the UK.  It is the users’ responsibility to satisfy themselves that their traps comply with the requirements of the act and are employed humanely and in accordance with the current legislation.

Mk 4 & Mk 6 Fenn Trap

The Fenn Trap has an ingenious and effective mechanism.  It has a tendency to jump when triggered and therefore, to ensure a clean kill, it must by Law always be set inside an appropriate tunnel or container.

Procull Squirrel Trap

Designed and manufactured in the UK, this is the latest spring trap.approved by DEFRA.

It is self contained in its own integral mesh cage with baffles to guide the squirrel to the strike position for the optimum humane kill.  An Integral setting lever allows the two powerful killing springs to be engaged AFTER you have set the trap, allowing you to position and adjust the trigger in complete safety.

A Pendulum trigger means that the trap is very versatile and can be used inside and outside and mounted horizontally or vertically, either way up on a fence, in a tree or on the ground.
