The Big CheeseUltra Power Block Bait Mouse Killer Kit - Twinpack, Refillable Bait Stations, 5x20g Brodifacoum Blocks, Rat and Mice Poisoning Blocks, Fast Acting, Biodegradable, Indoor and Outdoor Use

Great product with excellent packaging and easy-to-follow steps.

Since I e been using this product I’ve not seen any. Not saying there isn’t any! As they are taking the bait

So my daughter managed to bring home a mouse from the stables. This mouse is ruling my house. So far it’s eaten 2 blocks of poison and keeps coming back for more. Now I hear you say we must have more than one? Nope this one is very distinctive (lack of tail) and it’s the only one we see. No droppings it just helps it’s self to food and buggers off. It has jumped on my bed. Sat with my staffy and most recently climbed the stairs whilst we watched. This is one tough mouse. I have bought kind traps and now the poison. We have tried the bucket trick. This little bugger is too clever for us mortal humans. I have made sure there is no food anywhere and cleaned my house till it shines. So it’s only food is the poison. Still it lives?The short version I don’t think the poison works!

After about an hour trying, I finally managed to get it open so I could put in the bait. I had missed the sticker on the side that told you what to do. It might be helpful if they also showed this on the product packaging, as it is nowhere in the instructions. I even went to the Big Cheese product support page, but they don't show this model.It remains to be seen if it works. I will post again after I see any effects!

We have no more mice

Has been in the house for ages and no results. Obviously can’t return it so complete waist of money

Used,bait eaten, and no evidence of mice, so appears to have worked.

I've used these products before and never disappointed. Placed it 3 days ago and the locals are already feasting.
