This is a 15g sachet with two ingredients that we all know but put into one bait, it has said that it has a great kill rate and can be tracked due to its fluorescent technology. They claim the formulation improves acceptance of the bait by rodents.
I can say that within hours of placing this bait down in a loft it was being picked up by the rats see the video below and taken away, i will try and fix the bait and see what happens.

I will update this blog when i have data on how fast i got control of our rodent problem in this loft, but so far its looking good.
