Pest-Stop Little Nipper Rat Trap

Nice looking product, but disappointing performance. I have one old rat trap which I used successfully the night before the 4 new ones arrived. I have now used each of the four Little Nipper traps 3 times, with no success, a total of 12 sets. The cheese is removed without triggering the trap, I have even tried sticking the cheese to the plate with peanut paste and once tying it on with cotton, (a pain). All to no avail, the bait has always been removed without triggering. The old trap I have has two prongs on the bait plate and the spring is not as strong. I have deduced the spring maybe too strong on the Little Nippper traps and applies too much pressure on the trigger wire against the hole in the bait plate, stopping the plate slipping easily off the wire. I have set them carefully and as fine as is possible but without success. Best regards, John Williams
