1. Place the tunnel: Place the tunnel where you've seen signs of rat activity, lengthways along fences or walls, or in compost bins or areas of dense undergrowth. Ensure the tunnel is completely stable.

2. Remove the lure cup: Locate the lure cup on the underside of the T-Rex trap. Twist it to the left to unlock and pull it out. 

3. Fill the cup: Fill the lure cup with a small amount of your preferred bait. Options include peanut butter, mayonnaise, choc spread, cheese, and nuts. Do not use toxins.

4. Replace the lure cup: Twist the bait cup to the right to lock it back in place. 

5. Set the trap: Squeeze the back end of the trap until you hear a click. This will hold the trap jaws open. 

6. Position the trap: Holding the back of the trap, slide the set trap, bait-end first, into your wooden tunnel box. Position the trap close to the back of the trap box to prevent harm to non-target species.

7. Replace the mesh on the service entrance

8. Check Regularly: Check your traps frequently, and report catches to RTH via the form (link)

Important Notes:

• Safety: Always wear gloves when handling traps and catches to avoid transferring your scent and to protect yourself from potential diseases. 

• Tunnel: Ensure the tunnel box is properly secured before leaving it, keep both ends clear of vegetation, and ensure the mesh ends are filed smooth at the entrance.
