A Guide to Approved
Grey Squirrel Traps
Grey squirrel attacking bird feeders

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.


All users must satisfy themselves that their traps comply with the requirements of the act and are employed in accordance with the current legislation and a correct risk-assessment of the traps’ vicinity.

The springs’ in these traps are very powerful.  When these traps are set, never allow hands past the tunnel entrance.  These traps have the potential to severely damage the human hand!


Always correctly position spring traps and protect them from non-target species.  


It is the users’ responsibility to ensure that traps are employed humanely and in accordance with the law.

Mk 4 & Mk 6 Fenn Spring Trap


The Fenn Trap is named after the inventor and clones manufactured by other makers are known by the same generic name “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 always be set inside an appropriate tunnel or container.   When used correctly the Fenn Trap is excellent for squirrels and rats.

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 two examples illustrate the diversity of spring trap designs available.

Kania 2000 Spring Trap


This example comprises a metal box enclosure with a front access opening and a rear bait compartment.  It incorporates a torsion spring coiled about an axis normal to the front entrance and having tangentially extending free end arms.  This trap provides a high degree of certainty of killing and a high degree of safety for the trapper when setting.

If you use spring traps and harm a protected animal or bird, be aware that you could be fined for negligence for not having properly assessed the risk!  If in doubt, use a live catch trap.
