Something to be aware of is that this is bait, so mouse activity will increase when you start using it. The mouse (let's face facts though, it's mice, plural) definitely liked this. The first night we left it under a spot we knew they had been, the next day it had been moved to under the sofa. 2nd night it disappeared completely. 3rd night we heard them in the walls and could actually hear the block being dragged around! We found out where they were living, found the block and noticed it had been nibbled so began leaving them a block under the dishwasher each night. They ate sooo much, and they were definitely eating it and not just taking it to store - the blocks were nibbled right down. Because we were feeding them they stopped coming out of hiding and just happily lived quietly (well not quietly, they are so loud when nibbling the blocks!) I don't know if any died during this 2 weeks though because they're pretty well hidden, but unfortunately I lost patience and decided to add a single feed poison to the arsenal. Which they also devoured. 3 days after starting that I came downstairs to a terrible smell in the kitchen. Had it finally worked? Well it's been 3 days now since we last left a fresh block and sachet and they have not been touched, and we've not heard anything, so I'm quietly confident they're gone. (We'll pull the dishwasher out and find out for certain in a couple of days!) I would say this is a good product because they definitely eat it, I just can't be certain that this is what finished them off. It could well be that we had more than we realised and some died during the 2 weeks we were only using this product. Review: End of the road for rodents - First of all I have to say that I prefer not to kill any animal, even rats. However I had to resort to a poison since all else failed. I noticed the rats were tunnelling under my house in two places. I would fill the holes with metal and concrete, only for a new tunnel to appear within hours. This intervention is meant to disrupt their routine and scare them off, however they were determined to get into that space under the house as they clearly saw it as home. It was a race against time in Summer, when their numbers would only go up and they might eventually end up in the house in large numbers, giving me a very serious problem. One of the areas I covered with tarmac which seemed to work, though the other was near the lawn hence a lot more difficult to stop. I tried a rat trap which had worked before - I put some tempting treats onto an unloaded trap inside a bait box to get them feeding off it – but it was untouched. They must have known what that was, they are clearly quite streetwise so I half expected they would be wise to any poisoning attempts. I saw this product on desertcart and it seemed to have good spec and reviews, so gave it a try. It uses Difenacoum which is well used commercially and is meant to work in 3-7 days. Quick delivery thank you very much. I placed one block in the bait box, just outside the latest tunnel – and it was gone when I next looked. Following day, another block – this also disappeared. I replaced that, and this time it wasn’t touched. Within a week of the first use, It seemed there was no more activity, so I filled in the remaining tunnels and have seen no new ones since. Which means this stuff has basically worked and I wholeheartedly recommend it – should all else fail of course. The lesson learned is that you really need to avoid them moving in to start with, by not putting bird food on the ground, keeping compost secure and filling in any tunnels immediately rather than waiting for them to become established. But if the rat must die then this is an excellent product. ## Features - May cause damage to organs through prolonged or repeated exposure. - Use biocides safely.

Mine keeps eating no dead body or smell found yet** A: I found these blocks to be very efficient and fast working (have actually only used one so far). A tiny amount had been nibbled overnight and the following morning we found a dead mouse in the next room. I left the block in place and a couple of days later the whole block had disappeared completely! We never did find it but didn't find any more mice, either dead or alive. I can only assume that another mouse had found it and somehow taken it through a hole under the floorboards, which is amazing as these are big blocks! (We live in an old Victorian house with lots of drafty holes and gaps). Mice are so small so there is not a lot of smell anyway when they die (apart from their urine) if they are under the floorboards. I would recommend these blocks as they really seem to work well (although I still don't like killing creatures, but you can't have mice damaging your house etc :-( ) **Q: How does rat find them if it's wrapped up do they chew through the packaging** A: It is best practice to remove the block out of the individually wrapped red block. **Q: Do you have to have bait station** A: Recommend using the bait station so the rodent doesn’t spread the bait around too much, **Q: Got a rat coming up sewer and chewing through waste pipe - will this be any good?** A: Is it the pipe to the wc? Rats are attracted to the light so you can get a fitting that has a hinged flap which lets the waste go down but blocks out the light and won’t let the rodents through. Painting white pipe work a dark colour or using a dark coloured pipe will also help ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works! *by A***A on 20 May 2022* I'll preface this by saying that I used this for 2 weeks and then stopped being patient and added a single feed poison alongside it.
