I use bin buddy in my grey wheelie bin, I sprinkle a bit in when it's been emptied then a bit half way through because it's emptied every two weeks, it lasts me a while so correct me if I'm wrong but it looked to me like she put half a bin buddy in each of her pull out indoor bins, I consider this excessive as well as all of her other chemical use, she could jump on the eco band wagon but she's as thick as alpaca shit so can't see any way to change her content
