CritterKill Rat & Mouse Killer Poison Blocks 300g – Rat and Mouse Poisoning Poison Sachets - All Weather Block Poison Bait (300g)

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 Amazon 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.

Arrived quickly. Looks good and is easy to install into the bait stations. Only thing is that they are so expensive. Not just you but in general. Doesn't seem fare when they are coming from someone else's garden. Especially as they are eating my flower bulbs. That's the only thing for them to eat in my garden. I try not to encourage rats and mice. But I can't stop my neighbours. I think they should be cheaper for the public. Though yours are the best value. Thanks

Hi everyone reading this review.I had a problem that I refer to as the kitchen wars, I had British brown rats digging their way into my kitchen. I’ve bought many products in my arms race to defend my property. The poison blocks, I may have not used the product in the way it intended or instructed on the box. I have blocked holes with expanding foam and wire mesh also I’ve used these poison blocks in the mix/combination. Each block comes in its own individual packet, so I/you don’t even need to touch it with your bare fingers. I can confirm that the rats digging and excavation projects has stopped, at the moment. At £7 I thought why not, I’ve been pleasantly satisfied with this product as I no longer here noring and chomping in my kitchen in the late and early hours of day.

I bought this product to solve a rat infestation I had coming into my garden from a shared alleyway, I put out 2 blocks initially that was eaten quickly that night then I put out 1 block for the next 3 nights that was eaten and now on 4th night the block was not eaten so I think this has now killed off the infestation for me, this worked well for me and quickly, very pleased with the outcome so far and I still have some of the product left if I need to use again later.

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.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.
