We have 4 Chihuahuas, a cat and a miniature horse. Keepi g the odors down starts with making sure you keep everything clean and making sure nobody is secretly marking territory. An ultraviolet light is the number one tool in fonding those accidents you cant see with your plain eyesight.
I no longer live out west. But these were something we kept on hand all the time to find scorpions that hide out and come venturing out at night when the ground cools. If you turn the lughts out and search with the UV, they lught up like Christmas lights.
