Pest Expert Formula 'B' Mouse Killer Poison is a highly effective professional-grade mouse bait delivering 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! 

  • Contains maximum strength Brodifacoum
  • Made from top quality whole-wheat grain
  • No wax content so highly palatable to mice
  • Suitable for indoor use
Product Information
Pest Expert Formula ‘B’ Mouse Killer contains maximum strength Brodifacoum, the strongest and most effective mouse poison for sale to the amateur market.

Manufactured using only the finest quality whole-wheat grain, Formula 'B' is wax-free, which makes it highly palatable to mice, ensuring excellent uptake and rapid results.

Formula 'B' can be used both indoors to get rid of mouse infestations. Formula 'B' is also suitable for mouse control in business premises such as restaurants, food premises, factories and farms.

Directions for use
Our heavy-duty lockable Mouse Bait Boxes should be used to securely house the poison when baiting outdoors or in sensitive areas. Open each bait box and fill the central chamber with a sachet of Formula 'B'. Close/lock the box and place where mouse activity has been noticed. Check the bait station every 2-3 days and replenish poison as necessary until no more bait is taken. 

When using any type of rodenticide, care should always be taken to ensure that it is not accessible to children or non-target species such as pets or other forms of wildlife. 

For the best value for money, please see our
Mouse Kits, which contain two types of mouse poison - Formula 'B' Mouse Killer grain bait and Mouse Bait Blocks – and are supplied with lockable indoor mouse bait stations, bait trays and a professional advice sheet to help you achieve and maintain successful mouse control.

Don't mess about. Get the real thing from and give the rodents in your garden a hell of a bad time! They are the best company for price and service. No frills - just dead mice!

Reviewer: Harry from Gloucester   5 Stars

At last we can buy a professional product for controlling mice. Easy to use. And a lot cheaper than a visit by the mouse man. We have horses and stables, live in the countryside and mice are always around but using this, just keeps the problem at bay.
