Ohh, there are some reasons for this.
First, the rat trap can become dirty. Do you clean it regularly after the successful rat’ killing? Maybe you’ll find old blood or parts of the fur if you’ll look in the trap right now. Clean it with a damp rag and check it’ work again. The second reason is batteries - change them and turn into the trap again.
Finally, if everything is ok, but the rat traps doesn’t work it means that it has broken. So, you need to contact the seller in order to find out is it possible to change it – or you can choose a new rat trap from our rat traps review.
