Place the bait in the center of the trap's bait platform. This ensures that the rat must engage with the trigger to access the bait. Placing the bait off-center might allow the rat to nibble without triggering the trap.

Pre-Baiting:
Before setting the trap, pre-bait the area by placing bait without setting the trap. This helps the rats become accustomed to the presence of the bait and may increase the chances of them interacting with the trap once it's set.
