Product Information
Formula 'B' Rat Killer contains maximum strength Brodifacoum - 4 times stronger than Bromadiolone - making it the most effective rat poison for sale to the amateur market.

Formula 'B' is made from quality whole-wheat grain and contains no wax, which makes it highly attractive to rats and ensures excellent results.

Formula 'B' rat bait is ideal for domestic use as it can be used both in and around buildings to eradicate rat infestations in garden sheds, lofts and kitchens. Formula 'B' is ideal for effective rodent control in commercial settings such as in food premises, warehouses, factories, restaurants and shops, as well as for agricultural use in smallholdings, farms, and riding stables.

Directions for use
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. Our heavy-duty lockable rat bait boxes should be used to securely house the rat poison.

Open each rat bait station and fill the central chamber with a sachet of bait. Close/lock the box and position at the edge of a wall/fence, along a rat run, or wherever else rat activity has been noticed. Check each rat bait station every 5-7 days and replenish rat poison as necessary until no more rat bait is taken. 

For the best value for money, please see our Rat Killer Kits, which contain both Formula 'B' and rat bait stations and are supplied with a professional advice sheet to help you achieve and maintain successful rodent control.

Contains Brodifacoum at 0.0029% w/w

Prompt service.

This was an easy purchase of a product that seems to be working well.

Reviewer: David Brown from Hazlemere   5 Stars

Beter than expected

I was kept fully informed of all aspects of the progress of my order and it was delivered more quickly than I expected

Reviewer: Peter Harris from Grantham   5 Stars

Did not have to send for the Daleks!

The product appears to have done the trick, I have not seen any evidence of the rats since baiting all the traps round the property and in the warehouse. Most of the bait has disappeared and I have refilled the traps, some of them are still full, so hopefully the problem we had, has for the time being, gone away. Will reorder this product when required.

Forget the rest, this is the best.!!

We have an ongoing problem with rats and mice, as do very many people without even realizing it. I have tried many leading brands of rat-killer over the years, with varying degrees of success. However, I do not need to look any further. This product does the business.!!!

Excellent product and service

Reviewer: Peter Jones from Middlesex   5 Stars

We bought the Formula 'B' rat poison and some bait boxes to deal with a family of rats which were living in our garden. Within just 5 days all of the rats were dead and no further activity has been seen for 4 weeks now. I've been very impressed with the service from Pest Expert, the quality of products and of course the results achieved. I would definitely recommend this company and use again, but hopefully won't need to.
