I haven't had it long enough to see how effective it is, I followed the instructions but none has been taken as yet. I have heard from other people who have used it that it is good. It uses the most up to date chemicals and at the maximum doses. It was cheaper to buy three packs on e-bay than order directly from the supplier who charges postage.

Although mice took bait from proper box, rat would not go near it (probably too big to get into box anyway?) - all on CCTV! However, once bait exposed, rat ate four whole blocks in two nights...and no more rat. No mice after short period either. Very impressive; bought three more boxes, but thankfully, no need for them now. Highly recommended product.

Formula B is the best poison on the market, I've used other poisons in the past but they're not as good as Formula B.The rats can't resist it & took care of the problem within 48 hours. Highly recommended.
