Review: Result - Perfect use every winter as a precaution. Not had any issues since using this.
Review: Impressive!! Very attractive poison for the rats. - We had rats in the underground and every evening they liked to come to our kitchen, the rats were coming from a next door old house, we tried several non lethal traps for several days before trying this poison, however the animals were "too smart" to enter there (we trapped just one rat with this non lethal traps). Because of this we tried this poison, in the bags there were 17 blocks rather than 15, so lucky me! I placed 6 poison blocks in the kitchen and I closed the door, after 20 minutes I returned, ALL THE BLOCKS HAD GONE!, so I placed 4 blocks more and I left the kitchen, 10 minutes after, ALL THE BLOCKS HAD GONE, so finally iI placed all the remaining blocks in the kitchen, after a while I got back and ALL THE BLOCKS HAD GONE. So basically the rats took all the poison blocks in less than 2 hours. After that day we havent seen/heard the rats again. In one side I felt sadness as we killed all the animals, but we gave them the safe option (non lethal traps) and they didnt want to enter, however we placed this poison and they took it inmediately... on the other side we resolved a problems we had for months in few hours.... I would recommend you to try non lethal traps prior to try this poison, at the end of the day they are just lost and scared animals and we must give them a second chance. However if you decide to try this poison, be sure that it will be very effective.

### ⭐⭐⭐⭐ Seems to work as it’s keeping them at bay
*by D***I on 25 October 2021*

The blocks are easy to handle and do get taken from my garden on a regular basis. I’m presuming they work as neighbours find the dead rats at their gardens , as I think their nesting places are in neighbours gardens .
