We use this product in our office and in our rental houses. We had a severe problem with mice bringing sunflower seeds into the copier. With Fresh Cab, there has been no sign of mice, in the copier or in the papers stored in drawers. It does not harm pets, and it smells wonderful. I never need to worry about clients wondering about the weird odor in a law office. We nearly lost a cat a few years ago because he had eaten a mouse who had been poisoned so I have been adamantly opposed to toxins.
