OWLTRA OW-5 Ultrasonic Rodent Repellers

This is a good idea in practice, as a more humane way to eliminate a rodent, however it did not work for me. I had a rat in my attic. I have no idea how it got up there tonthis day, but I could hear it scratching at night and/or when it was quiet. He could not get into the actual house/living area. I purchased this device and I honestly thought he was going to be done for the day I set it up, but boy was I wrong. I also bought an indoor Eufy camera to watch/monitor it. I set this trap up there and set the camera up in the attic facing the trap. It is 100% complete darkness up there when the light is off, but the cam was a PTZ cam with excellent night vision. I added american cheese and peanut butter with some fresh grated parmesan on a piece of tortilla in the bait trough (figured his last meal might as well be a good one). I also added a very small piece just inside the entry of the trap and a small piece just outside in front of the trap. Within no time I saw him eat the piece outside of the trap, as well as sniff all around the trap, focussing heavily on the vents right near the bait trough. Every so often he would return and sniff around the trap and look at the entry, but not enter. Finally maybe 5-7 days in (already too long for me) he reached in and grabbed the small piece inside the door. So I started thinking today is the day. Then over the next week he was beginning to go in further and further each day, reaching about 3/4 of his body in the entry at the peak point. However, I had to put a firm deadline that if he doesn't go all the way in TODAY and get zapped, I am going snap trap on his azz. Well, the deadline came and he never went all the way in, so I went up there and set a snap trap, turned off the light and closed the entry to the attic. I went outside to check the mail or something real quick, came back in and sat on my couch and then heard a noise and got a notification from the camera. Checked it and saw him get snapped. Within 10 minutes of placing the snap trap, he was done for. So, my point is, while this trap might work, in like a month to who knows, maybe 3 months, in the end a good ole fashioned $5 snap trap worked swiftly and immediately. One after thought of mine, is that they are in some ways much smarter than they are given credit for. I realized that I had not set the trap against any sort of wall, so he was always able to walk around all 4 sides of the trap and the top too. So I think he realized this was a box that went nowhere. A dead end. Perhaps if it was against a wall where at least one side of it he could not investigate, see or access, he might then think this is an opening into further exploration, like an opening into a wall or something, and not just a dead end box. Regardless, it ended up being the snap trap FTW in literally 10 minutes time of being set up. I gave this unit 3 stars because I'm sure it probably does work, and maybe more likely if set up against a wall. However, I think what would probably be the best idea for this is to have an opening/entry on both ends that they can see right through and out the other side, with the bait trough in the center/middle. I think a mouse or rat would be more inclined to go in if they can see that it's just a tube/hall with an exit ahead of them, and then when they get inside to the middle point, bzzzzzz. Oh, and let me tell you, I read about them and everything says they have good low light vision. I have to say they have excellent NO light vision. I watched this thing easily run along a rafter, and turn exactly when the rafter turned, and also hop from one thing to another. So either they have echo location or sonar, or maybe they emit infrared from their eyes, because they can SEE in complete darkness.
