How are sticky traps for rats even legal?

Tonight, when my brother and I were on a walk, we came across a rodent stuck in a sticky trap. It was one of the most horrific scenes I have ever witnessed. My brother was the first to spot the rodent. The rat’s lower half was completely stuck in the glue. When it saw us approaching, it tried to use its hind legs to move towards the manhole cover. Its condition was absolutely miserable. Its long tail was entirely stuck in the trap. I tried to free it using a stick, but I had no idea how sticky a sticky trap could be. I used the stick to set it free, trying so hard, but it was clearly painful for the rat. After a long struggle, we finally managed to free it. This experience shook me to my core. The sheer helplessness of that animal made me question how such inhumane traps are even allowed. These devices don’t just capture rodents—they inflict prolonged suffering, forcing them to die slowly and painfully.
