I have made some of those, they managed to get all the bait and not a single rat fell in, I still set them up, I then tried it with larger containers so that the rats couldn't stretch over from the sides, but it still didn't work, then I started oiling the bottle that spins, still nothing, I figured that they might be getting out after falling in, so I oiled the sides of the capturing container and added oil and a water to the bottom of the container - but alas NOTHING LOL
