Professional-quality Rat Poison Bait Blocks specifically formulated for optimal results. Containing the strongest concentration of Brodifacoum – This should NOT be confused with the weaker, less potent rodenticide, Bromadiolone.

Despite what many companies claim, Pest Expert Formula B+ provides the strongest range of rat and mouse poisons available in the UK and is designed to kill in a single feed.

Proven to be up to 4 x stronger than other poisons containing Bromadiolone or Difenacoum, the result with Pest Expert Rodenticides is always faster, more effective control and therefore better value for money! 

  • Highly-effective rat killer, able to control even warfarin-resistant rats
  • Single-feed Brodifacoum at maximum strength
  • Totally weatherproof so ideal for outdoor baiting
  • Wax-free 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 uniquely powerful rodenticide, Brodifacoum, at the maximum legal concentration (0.0029%), guaranteed to achieve optimal results. The formulation is so potent that a single feed is often enough to kill a rat.

Made from a wax-free 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 bait 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

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.

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.

Open each bait tunnel, place blocks onto the metal rod and position in place. Close/lock the boxes and position along a wall/fence, rat run at intervals of 5-10m (or wherever else activity has been noticed). Check the tunnel every 5-7 days and replace blocks as necessary until no more bait is taken.
