Would someone kindly help with correcting the rough translation I have made from English into French so that it is 100% grammatically correct. Many thanks:-

Original English.

Springer Vermin Traps

This is the classic Fenn type humane trap for vermin

These traps are approved for use on rats. The traps must be set in natural or artificial tunnels which are suitable for the purpose.

Our legal traps are clearly stamped with the Springer brand name & Mark 4 and Approval No.2111.

Our traps have the trigger system made entirely of brass as this permits a more sensitive and quicker response. This will never rust or fail over time.

Another important feature of our traps is that the springs are annealed (heat treatment) during the manufacturing process so that any residual machining and forming stresses are entirely eliminated. This eliminates any possibility of spring failure or force degradation. You can therefore look forward to having many years of reliable service from the Springer Mark 4?s.

These are humane traps that instantly despatch the target species. They are tested and licensed for use.

Buy the best and buy in confidence.

Ces pi?ges sont approuv?s pour les rats. Les pi?ges doivent ?tre fix?s dans des tunnels naturels ou artificiels adapt?s ? cet effet.

Nos pi?ges juridiques sont clairement marqu?s avec le nom de marque Springer et Mark 4 et l'approbation no.2111.

Nos pi?ges ont le syst?me de d?clenchement enti?rement en laiton car cela permet une r?ponse plus sensible et plus rapide. Cela ne rouillera jamais ou ?chouera avec le temps.

Une autre caract?ristique importante de nos pi?ges est que les ressorts sont recuits (traitement thermique) pendant le processus de fabrication de sorte que toute contrainte r?siduelle d'usinage et de formage soit totalement ?limin?e. Cela ?limine toute possibilit? de d?faillance du printemps ou de d?gradation de la force. Vous pouvez donc attendre avec impatience de disposer de nombreuses ann?es de service fiable aupr?s des Springer Mark 4's.

I'm very taken by the idea of tempting the varmints into "pi?ges juridiques" and look forward to progress reports. Meanwhile cf perhaps http://www.linguee.fr/francais-anglais/traduction/pi%C3%A8ges+juridiques.html.
