I use this within the girls cube. I like it because the cube always smells fresh, and it soaks up any excess liquid.
We have bark down in the run for the girls although we clean as much mess up as possible it is not always possible to clean everything. However, we sprinkle this powder around the coop every four-five days which kills things we can't see. It also eliminates odour very effectively. I would definately recommend this product.
...Judging by the immediate effect on any unlucky earth-worms which get caught in the crossfire. Shame about that but I really needed this to deal with a recurring chook-worm problem and, together with Flubenvet, it seems to have been effective.
Also neutralises nasty niffs as a bonus. Recommended.
the product worked well but as we have a large area to cover did not last very long.
