Rat Killer Poison 3kg - Pest Expert Formula 'B' (Professional Strength - 30 x 100g)

Our Price: £18.95

Pest Expert Formula 'B'  Rat Killer Poison 3kg (30 x 100g)

Pest Expert Formula 'B' Rat Poison is an effective rat killer that contains the strongest formulation of Brodifacoum available in the UK. Brodifacoum has proven to be so good at controlling rats - 4 times stronger than Bromadiolone - that it is now the most powerful formulation of rat poison in the UK amateur pest control market, and is known for its high success rate.

The fact that this rat poison is produced in the UK means that it doesn’t contain any of the attractants which are often added into imported products to increase uptake and disguise a poor quality poison which can take much longer or be completely uneffective.
This poison is the best rat killer to deal with an infestation, follow our easy steps below to execute an effective and fast pest control solution. 
  • Place rat poison in areas where you have noticed rodent activity, e.g. on rat runs, along fences or walls, where droppings have been found, near to or inside rat burrows.
  • Use 100g of rat poison at each baiting point, located roughly 10 metres apart, or 5 metres where high levels of rat activity are noted.
  • Check baiting points every 5-7 days, replacing any poison taken. When feeding stops, this is your indication that control has been achieved!
  • Use tamper-resistant bait boxes to make poison inaccessible to children, pets, birds and other non-target wildlife.
Formula 'B' Rat Killer is ideal for eradicating rats in both indoor or outdoor situations, including garden sheds, lofts / roof spaces, under kitchen units, etc. It is also perfect for commercial use in warehouses, factories, restaurants, food premises, and farms.

When using this rat poison care must be taken to ensure that it is not exposed to children, pets or non-target species as it can cause a lot of harm if ingested. We have heavy duty lockable rat bait station available to protect the poison in sensitive areas, see the related products below.

Contains Brodifacoum at 0.0029% w/w.

Authorisation No: UK-2017-1051-0002
Use Biocides safely. Always read the label and product information before use. 

Now supplied in 30 easy-to-use 100g measured sachets, enabling precise baiting for improved control.

Adrian Bennett-Essex-5 Stars

Our rat problem seemed to be worsening having tried some of the bright pink blocks and bright pink grain that I'd bought elsewhere (these were hopeless, the rats wouldn't eat it, not recommended). So I tried the Formula 'B' rat poison and a couple of bait boxes. This worked extremely well, the rats munched their way through it, within one week the rats were no more.... Finally, a product the delivers what it promises!

Pat Abbott-Bristol-5 Stars

We bought this rat poison as it contained the maximum strength active ingredient and I'm pleased to report that it didn't disappoint! It was a good value 3kg tub, a lot more economical than many of the smaller packs I noticed offered on the internet. The Formula B did the trick with rapid pace and our garden which backs onto fields and woodland is now completely rat free. Prompt delivery also. Overall a great product received in good condition.

Isobel Williamson-Jones-Hampshire-5 Stars

I bought this bait after searching for something stronger than the readily available stuff from retail shops - which is expensive and useless. The rats lined up for that at feeding time and came back for more. They ate this poison up every day for about a week and then the rate of eating slowed and we hope we won''''''''t see them again! Will definitely use it again.

Dan-West Midlands-5 Stars

Our garden rats enjoyed munching on this for 5 days. I have not seen them since. Glad to be rid of them. Formula B seems to be very effective.


I have bought from Pest Control Supermarket several times now for both their Pest Expert rat poison and the glue traps - Excellent company, top quality products, work every time!

Mr R Evans-London-5 Stars

Used Rat bait overnight, the rat was dead in the morning. Well done.

Dawsie-Dorset-5 Stars

The most effective rat poison without a doubt. Simple to use, simple to order, prompt delivery. Poison B is the only effective that I have found. However, I recommend covering the trays to keep the rain off, and be persistent, keep putting out the bait until they stop taking it- and you know why.

Dale Wolsey-Derby-5 Stars

Wonderful company. Product was beautifully packed and came incredibly promptly. I would highly recommend and use this company again should the need arise.

Pat-BrIstol-5 Stars

Excellent product (Formula B)which got rid of the rats! Formula 'B' Rat Killer Poison 3kg (With Free Nitrile ) We bought this one as the active ingredient was different to the one we had been using as we felt long use of one brand seems to make the rats resistant(or maybe we were unlucky)This was a good value 3kg tub which is a lot more economical than the small ones most people buy in the shops. The Formula B did the trick and our garden which backs onto fields and woodland is now rat free. Prompt delivery and great product received in good condition.

Dee-Pontefract-5 Stars

User friendly website, fantastic speedy delivery, excellent service & product. Found this website after contacting pestcontrols compnanies. Who very clearly were solely interested in how much i would pay for numerous visits from them. Didn't seem to ask questions regarding my infestation, more on visits & costs. I found this company, purchased the same poison the pest controls used. The goods arrived the very next day, very economcial in cost, well packaged with clear and easy to follow instructions. I can use as and when I need and monitor the situation myself. Extremely pleased with the service and product. Wouldn't hesitate to use them again should I need to.


poison arrived quickly, rats disappeared quickly too thanks really pleased with this product, cheap and effective

Phillip-Daventry-5 Stars

This rat poison works Unfortunately, the rats attracted no doubt by our chickens, found their way into the house and could be heard running around in the walls. I found a couple of holes, and put the poison nearby and under furniture with short legs. Presumealy the rats were suspicious at first, but 2 nights later some pison got eaten, and the next day I found 2 very lethargic rats, which were easily caught and disposed of.

Jeffrey McGowan-Cheadle-5 Stars

MAKE PESTS A THING OF THE PAST! With a large garden and pet house containing 15 guinea pigs we were plagued with rats and mice. Tried a variety of products from supermarkets and DIY shops with little or no effect. If anything, the vermin population increased as the rodents chomped on what appeared to be corn dyed pink. The local council wanted £70 to make one visit. Tried this product with immediate results overnight. As well as the guinea pigs we have two German shepherd dogs running free, so the repellant had to be pet-safe. Excellent product and very customer-friendly company. Rat's the way to do it!

Roderick-Ellon-5 Stars

Kills rats stone dead. This company delivers the right product, right on time, I think I must have been just feeding the rats with the poison I got from the hardware store, but with the poison from Pest Control Supermarket I found the rats lying dead in the garden, I know where I will be buying my poison from now on should I need it.

Barry-Crawley-5 Stars

Kept updated on order process, decent price with fast delivery. First time that I'd purchased from and must say that all went very smoothly, as it should. I was updated with order status and the price that I paid was very competitive. The goods arrived very quickly.I put down one lot of rat bait which went and now second lot hasn't been touched and no more rats at present Based on this initial buying experience and performance of product I would recommend and buy again.

Frederick Michael-Thetford-5 Stars

My rats seemed to really enjoy your product for several days, but now I think they are stuffed!! I have five greenhouses, four of which had a rat or rats visiting regularly. They obliterated several pots of newly planted tulip bulbs and crocuses, plus they had devastated several other plants in their pots in the greenhouses for the winter. I put some of the product in each of the greenhouses every day and it was eaten daily for about five days. I know that they were consuming the poison as there was green coloured faeces in the areas. However, now the product is just sitting in the shelves and has not been touched for several days, so hopefully the problem is now resolved. Thank you.

Ms Steady-Hopton-5 Stars

Rapid delivery & effective solution I have been impressed by the excellent service provided by this company. The goods were excellent both in tackling the problems and in price.
