Pest Expert Rat and Mouse Poisoning Bait Blocks 900g Super Strength Poison

After catching & drowning two large rats in rat trap with just nuts, was getting worried about the next generation that weren’t yet visible but knew they were around my garden, so invested in 3 boxes of formula B & two safe housings to put poison in, out of harms way to hedgehogs! Have since seen smaller version of the adults rats, the boxes have been in garden nearly two weeks & on opening them after 1st week nothing has been nibbled at all, at sightings where I know they were, so either they have moved on (I don’t think so) or just don’t want to eat it! So very disappointed with this product as I’m going to have to buy alternative poison, so I have peace of mind that I’ve eliminated them!!

MAYBE WE HAVE A SUPER RAT BUT THE MORE WE GAVE HIM THE MORE HE ATE -2 WHOLE BOXES AND HE IS DOING JUST FINE! WE HADNT USED THIS BAIT BEFORE SO CANT SEE HOW HE IS IMMUNE OR RESILENT.

The rats in my north London back garden have got through ten boxes of this bait during the last 10 days! There are no signs that I'm doing anything apart from feeding them up for the cold winter nights.For example, all five bait boxes were emptied last night.I am beginning to doubt that this is an effective treatment given reports of increasing resistance to Bromadiolone which is the main ingredient in this product.

I used this to deal with my rat problem. Thought it might be more effective than my previous bait. The rats won't eat it, they preferd the previous cheaper bait I bought last year. My camera shows them going into the bait boxes, but when I checked, the bait hadn't been touched. The bait boxes are brilliant.

I bought quite a lot of this in 2022 to control mice in my large attic, it vanished very fast which was promising - but the mice didn't, so I used traps baited with peanut butter or chocolate hazelnut spread instead which works very well.Today (03.2026) I was lifting floorboards in the attic as I still have a few mice running about, & I found an active nest - full of chewed poison blocks !Oh well, back to the traps I guess !

My rat(s) have devoured almost 900g of your product and are still coming back for more!They obviously like it but it is not having the desired effect.Where do we go from Here?

Not eaten by the mice. Can still see The mice

They don't kill rats at all mine eat these for a snack
