Pest Expert Formula 'B' Rat Killer is a highly effective professional-grade rat poison delivering rapid results.
Formula 'B' Rat Killer is the strongest and most effective rat poison for sale to the amateur market as it contains maximum strength Brodifacoum (0.0029%), which is 4 times stronger than Bromadiolone when used against rats.
Formula 'B' is made from top quality whole-wheat grain and is wax-free, making it highly attractive to rats and ensuring outstanding results.
Ideal for use in domestic residences, Formula 'B' can be used both indoors and outdoors around buildings to eradicate rat infestations in garden sheds, lofts and kitchens. Formula 'B' rat bait is also suitable for achieving rodent control in commercial premises including restaurants, food premises, factories and farms.
Directions for use
When using any type of rodenticide, care should always be taken to ensure that it is not accessible to children or non-target species such as pets or other forms of wildlife. Our heavy-duty lockable bait boxes should be used to securely house the poison.
Open each bait station and fill the central chamber with a sachet of poison. Close/lock the top and position boxes every 5-10m at the edge of a wall/fence, along a rat run, or wherever else rat activity has been noticed. Check each bait station every 5-7 days and replenish as necessary until no more bait is taken.
For the best value for money, please see our Rat Killer Kits, which contain both Formula 'B' and rat bait stations and are supplied with a professional advice sheet to help you achieve and maintain successful rodent control.
Contains Brodifacoum at 0.0029% w/w

We discovered an exceptionally FAT rat coming into our garden and somehow climbed up into our bird seed feeder.
Happy to tell you the day after the poison arrived - we no longer have a FAT RAT - Just had a DEAD rat.
Very happy customer. Sorry I didn't think to take a picture of the dead rat for all to see.
Does the job
Great product. Does the job
I have used this product previously and always found it to be very effective, hence this re-order when I had another problem with rats on my allotment.
The product was used in accordance with the instructions and I am pleased to say that the problem has been resolved after the use of just four sachets! Excellent. Thank you.

Best Rat Poison About
This product from pest experts works a treat and very easy to use
Easy purchase process, fast delivery and as described excellent product. Would recommend.
It kills vermin, which is a great relief because stuff I tried from other suppliers either didn't kill rodents or they refused to eat it.
Good size packets of grain, have used other sites and packets are ridiculously small.
Excellent product excellent service
Would like to say a massive thank you the cost of your products so much cheaper than cost of X2 pest visit problem 1st started in my neighbors flat with him hearing the telltale sounds at night then other night at 10pm heard sounds above my kitchen obviously was in the crawl space so ordered the 2 bait box kits one for each of our areas as a start when he gets back we will set bait box up for him but in mean time I’ll keep my ears peeled am encouraged by fellow reviews keep up the good work
Used at the weekend and the rats ate it straight away. By Wednesday we've seen no rat activity, very impressed with the efficacy of the poison!
The products were delivered promptly. The poison has been eaten by the rats straightaway and after 3 days no more is being taken!
There is plenty left to deal with any other visiting rats who decide to move in!
Brilliant product and service. The poison worked so well and the rats have finally disappeared. Highly recommended
Just great! The rats have gone as quick as they came!
Used this for the first time and the results were amazing! Nothing but praise for Formula B! The pesky rats did not stand a chance!
NO MORE RATS....
Bought the Formula 'B' Poison and Rat Glues from Pest Expert. Both excellent quality, worked extremely well, and solved our problem within days. Overall, a good company to deal with and products did what they promised, so I'm happy.
Great all round service and product
Almost instant service with very reasonably priced product delivered safely,
done the job
put the rat killer down rats seemed to love it, 2days ..they ate it all. followed the instructions and no more signs of rats thank god.
The fast and reliable service was brilliant, and the product was great. Got rid off your intruder in less than 1 week. Great company to buy from.
Fast service, easy access, efficient.
Ordered Thursday afternoon, delivered Friday morning. Good produced, not readily available in shops, does the job
rat and mouse bait
the reviews by other people sold me on using this firm. After 2 days, no more rats. Put down bait twice. The gloves are very handy to disguise my human smell(rats are so suspicious, understandably)
Quick service/Good products
Quick service & sent me a text 4 hours before they were due to arrive so I didn't stay home all day & arrived exactly on time! This poison really works, takes a few days for them to take it but then no more mice!!!
Purchase of rat posion.
Very pleased with the process for ordering, tracking and delivery. Excellent service. I cannot comment on the product as I havent had it long enough.
excellent service from laptop to home
Easy to order. Good selection with information. So quick. Just what u need when u have a problem.
We had been experiencing an increase in rat activity in our garden although we do live in a very rural area. We tried a rat cage trap with absolutely no effect to try to use the humane approach, but as the rat population seemed to increase decided to try the Pest Expert products. We bought the twin pack of rat bait tunnels which are lockable and a pack of 8 rat poison bait blocks as a trial about two weeks ago. The instructions are very clear to bait the tunnels and place in known rat runs and leave for 10 days. We just checked the tunnels after that period and all the bait blocks have gone. We have noticed less activity so hoping this will solve the problem for the time being. We would have no hesitation in recommending Pest Expert products.
Worked a treat. Cleared out the nest.
Excellent service and product
All of the products that I viewed had good and easy to understand descriptions. Once I'd placed my order, I received updates on it's progress. The products arrived quickly and well packaged - and worked very well! Would certainly recommend Pest Expert.
I got a surtain amount of Rats as I got Bunnys ! They kill the Bunny Babys and I am desperate to have them gone I do not like to kill any ting but in this case is the Rats or the Baby Bunnys ....well even I feed them the poisson I bought I still see Rats after a week but less of them and I can detect a smell of the dead ones . I assume they are geting less in numbers and I hope it will be the solution as I battle since 3 years and will do so in the future if needed as they seem to come from the nabours to here . I just changed from the cubes to the this as the cubes seem to do them any harm ani moore !
Having bought from Pest Experts on line service , I can only say that this was a quick and fuss free experience, the delivery was quick and I received what I ordered which was well packaged. I would use the services of Pest Expert's again.
Great product,fast delivery.
Excellent product and great service
I ordered some rat poison from pest expert and it was delivered very quickly. I must also state that it has done the trick - after a few months using standard over the counter poison with no results, I am very pleased to say that the pest expert rat poison has eradicated my rat infestation. I would definitely recommend their products.
Dead little hairy things
Delivery, packing and communication very all very good. Product seems t be working as already found one ,little hairy thing, but bit to early to judge if 100% successful
Some months ago, I attempted to rid my home of a couple of rats that had found their way into our loft space (single level height). I used a commercial brand Rat Poison purchased at B &Q. I kept buying more and more of the stuff (not cheap) but some weeks later, after no success, I purchased you product, And it did what you said: it got rid of the pests in a week. Excellent. Recommend it 100 percent.
We purchased the most potent rat poison available, and within a couple of days we'd removed half a dozen youngsters' bodies...the rest of them are probably in the depths of the undergrowth or in the tunnels. Not seen any adult bodies yet (and they take longer), but they used to come out into the middle of the lawn to hoover up any dropped bird seed - EVERY DAY at the same time. No sign of them. Ordering was very easy and delivery extremely prompt, by a very nice man. I would recommend this company without hesitation.
