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

Our Price: £26.95

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.

Steve Naxton-Wales-5 Stars

This product is exceptional in doing what it says.

Second lot of the Pest Expert rat poison and it really is efficient. Living near a stream we constantly have rats visiting the garden and have to keep baiting on a regular basis.

Excellent product - excellent service. Recommended.

Roy Thompson -Monkwood Hampshire -5 Stars

Great stuff

First time buyer of this product its done what it says will buy again

Stephen Murray-Bristol-5 Stars

Very effective.

I have been purchasing this product through Amazon for a couple of years now and I find it very effective and fast in getting rid of the occasional rat which I see in the garden. I keep the tray in the bait box topped up and as soon as I see it's been eaten I know that the problem will have been solved, for the time being anyway, until the next one foolishly tries some!

Maxine-Hartlepool-5 Stars

my house became infested with rats, they were running in the attic, the walls and in the floorboards, we blocked everything up and i tried other traps and poisons to no avail. then i bought some blue pellet poison and put it everywhere. within 24 hrs they were all gone!!!! fantastic stuff!!


Put bait down for 4 days and they took it all...felt like I was feeding them !!!! Started to panic ,thinking I had a major infestation.....and then there was nothing. Had been having problems for weeks catching the odd one or two using traps but now no more. Would recommend to anyone.

christopher-Essex-5 Stars

The delivery was very quick and have used the poison. It seems to have eradicated the rats so will buying again. Good product and good service.

Alexander-Leeds-5 Stars

was very sceptical about these products having had environmental health round who frankly were useless telling me to get in Rentokil. I was getting 2 - 4 rats a day & they were coming up the brook so Rentokil would have not worked as they were coming from way up the brook. I bought 4 of your bait boxes & tunnels along with a large amount of loose bait & solid blocks. Having tried to catch the rats in humane traps I was getting distraught as I could not get to the end of them. Since putting down these bait boxes & tunnels the bait disappeared & so have the rats.

Thank you Pestcontrolsupermarket

Leighanne-Worksop-5 Stars

Jack-Essex-5 Stars

Next day delivery and I was kept informed of progress. Products are simple to use and much better value for money than buying similar in shops. We had evidence of rats so the whole house has been treated and there are no more rats.

Natalie-Birmingham-5 Stars

Top quality product, 3 days after putting the poison down, I see no more rats. Formula B is the best poison I've ever used. Thanks guys *****

Kenny-Colchester-5 Stars

Have used this company for a few years now and all the products have been excellent. I live in an area with lots of rivers and underground streams (my house would have been IN the New River before it was straightened!), plus a few neighbours have chickens, so rats are a big problem. I've used a few other things previously, but they are more frustrating than effective, thus a waste of effort and money.

Whenever we see any rats in the garden, I pop some Pest Expert products in the way and the rats oblige by eating them and disappearing..

Richard-York-5 Stars

This is the best company I have had the pleasure to deal with i have placed two,orders with them they constantly send you emails to tell you the status of your order even the time of delivery and it always happens.Wish every company was the same. Rat Poison works very well too! Richard

Product arrived on time and performed exactly as described. We had problems with rats in the chicken’s enclosure but after just a couple of days the problem has gone!

Lydia-Wakefield-5 Stars

Ordered rat poison Thursday, delivered the following day and, although it needed two applications, eradicated quite a large number of rats. Use of other baits had failed to solve the problem so I am particularly pleased with this product and at a reasonable cost. Would recommend this product and company to anyone.

Pest control have a good range of products and are top quality, not like some of the weaker products that you can buy in shops. There is an easy order process, quick delivery and website gives practical information.

Kevin Jones-Swansea-5 Stars

Excellent service.

Can't fault delivery time, product arrived the next day and was well packaged. Excellent value for money as it is doing what it says on the tin (Or tub in this case!) This is my first purchase from this website, and I will be using them again when I require anything else of this nature.
