This really works. I've tried everything to keep the dog from chewing on the carpeted stairs. He takes one sniff of this and walks the other way! One word of caution, however...I used a toothbrush and flicked some on my freshly potted flowers outside and within hours the leaves of some of the flowers shriveled up and died. Only one type of flower did this. So if you've got a 'digger' in your family, maybe try to spray it on the dirt, not the leaves.
