Formula 'B' Mouse Poison Bait Blocks are formulated with maximum strength Brodifacoum, creating a powerful and fast-acting rodenticide which delivers rapid 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! 

The easy-to-use blocks are highly palatable to mice and are weatherproof, making them ideal for use to control mouse infestations both indoors and outdoors.

  • Maximum strength Brodifacoum 
  • Fast-acting advanced formulation
  • Highly palatable to mice
  • Weatherproof for outdoor use
  • Multi-faceted to encourage gnawing
  • Easy-to-use 20g blocks
Product Information
Formula 'B' Bait Blocks contain the maximum strength (0.0029%) of the powerful single-feed rodenticide, Brodifacoum - an anticoagulant with immediate results for fast and effective rodent control.

The unique blend of ingredients creates a highly palatable formulation which is irresistible to rats and mice, while the multiple edges encourage gnawing, both factors helping to increase bait uptake.

Specially formulated to withstand extreme weather conditions, including damp and humid environments, and resistant to mechanical damage, these blocks are ideal for both indoor and outdoor use.

Contains Bitrex - a bittering agent to prevent ingestion by children and pets.

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 mouse infestations: Use bait points of up to 20g. Place bait points 5m apart reducing to 2m in high infestations. Mice are very inquisitive and it may help the control program to move baits every 2-3 days at the time when bait points are inspected and/or topped up.

We advise that poison is housed in tamper-resistant bait boxes to prevent access by children, pets and non-target animals.

Reviewer: Heather from Milinthorpe   4 Stars

great service - mice seem to have departed

The little boxes arrived promptly and seem to have controlled the mouse population in just a few weeks. Some of the boxes were stiff to open and the blocks were very popular in some positions. 8 blocks might be enough for this winter in 3 sheds.

Reviewer: Julia Lloyd from Hastings   5 Stars

Really efficient.

The mouse blocks arrived very quickly and were delivered in an hour's slot. We appreciated that and being kept informed about the progress of our order. I cannot comment on the efficacy of the poison as a combination of cat and trap have triumphed for the moment. However, we are confidently ready for the next onslaught.
