Unfortunately, there are rats, which are much too cautious to fall into this trap. I have the cameras now with Wild observed since 2 months. Unfortunately rats are not like in the video on You Tube is shown. The great triangle trap at You Tube only works with mice. I have been here for years. This electrical case is here with the best bait in a high traffic area for 4 weeks and the rats do not care. I can not recommend this case. Had carried away from the positive recessions here have so much money to spend. My recommendation is 60cm box traps, infrared sensors and retrofitted with electrical tripping. It-Yourself and very catchy. Therefore, I can give a maximum of a star here. Actually, not even the.
