Review on NaturVet Yard Odor Eliminator: Eliminate Stool and Urine Odors from Lawn and Yard - Perfect for Grass, Plants, Patios, Gravel, Concrete & More! by Rosa Hughes

I sprayed at night so as not to disturb the neighbors because I didn't know what to expect. I've waterproofed the yard and concrete porch and it works. I could sit on the porch without smelling the urine. It was awful and difficult to read a book or coffee and even better eat. It's a sunny day and I really enjoyed sitting outside for a change. I'm not sure how often I need to spray, which doesn't matter because it works. Now I'm waiting to see if my neighbor notices. She loves to complain and comment.
