  • Highly-effective rat killer, able to control even warfarin-resistant rats

  • Totally weatherproof so ideal for outdoor baiting
  • Unique blend of ingredients makes blocks highly palatable to rats
  • Multiple surface design encourages rats’ habit of gnawing
Product Information
These premium-grade Rat Bait Blocks are formulated with the unique single-feed rodenticide, Brodifacoum, at the maximum legal concentration (0.0029%) to create the best rat poison and achieve optimal results. 

Made from a unique blend of food-grade ingredients to increase palatability, these bait blocks have also been designed to be multi-faceted, to provide rats with multiple gnawing surfaces. Both these factors aid rat poison acceptance/uptake, helping achieve rapid eradication of a rat infestation in your home or business. In addition, as these blocks are weatherproof, they are perfect for outdoor baiting.

Directions for use
Place bait where there are signs of rodent activity like fresh droppings, inside or near nests and burrows, runways and rodent feeding places. Place bait points throughout the infested area. It is generally much more efficient to use a larger number of small bait points compared to a smaller number of large bait points. Large bait points increase the risk to wildlife and to other non-target animals.
For rat infestations: Use bait points of up to 60g. Place bait points 10m apart reducing to 5m in high infestations. Do not move or disturb bait points for several days after laying bait. If no signs of rat activity are seen near the bait after 7-10 days, move the bait to an area of higher rat activity.

When using these Rat Poison Blocks outdoors or in sensitive areas they should always be securely housed within tamper-resistant bait boxes to make them inaccessible to children, pets and non-target wildlife.

For the best value for money, please see our Rat Bait Block Kits, which include both Rat Bait Blocks and Rat Bait Tunnels.

Formula 'B' Rat & Mouse Bait Blocks...... We have rabbits, Guinea Pigs and wild birds and the rats are attracted to their feed. For years we've had rats but this year they've been more abundant. After setting 11 bait stations around the garden. Within a week, only one of the stations is being visited, when a week ago the bait from all stations was being taken over night. Not seen a rat nor heard squeak for days. Have to say, the cats look lost ;) Would most certainly recommend this product in ousting them critters!

Reviewer: Hilary Dowdall from    5 Stars
I bought "rat poison" and at first, I thought I was "feeding the rats" as they seemed to love the "food" I spoke to an adviser who explained that I was "drip feeding " my rats and suggested increasing the quantity of bait and the number of sites, assuring me that there was no "resistance" to the bait. It was very helpful and reassuring and it certainly now works!!!!! My rats are in decline, but I have just ordered more bait to keep on top of the problem. (I keep hens & ducks and live in a rural situation) Excellent product and good backup advice. Many thanks!

Reviewer: Andrew Eamonson from Carlisle   5 Stars
To be honest Pest Expert just seem to come out near top of search enquiry. After reading a few reviews I ordered a "kit" to help deal with rats. So far seems to be working, bait disappears after a couple of days and I haven't seen any rats since putting the box down. Service from ordering to delivery was quick and painless. Would recommend to anyone looking for pest control products.

Reviewer: Susan from Sunderland   5 Stars

Reviewer: Mr Saunders from Oxford   5 Stars
After ordering from pest expert I was firstly impressed by the speed I received my order and then by the quality of what I had ordered. I have set up the traps and poison and may I say there have been no sign of the Rats. Thank you for an excellent product and all the pieces of equipment that goes with it.
