Shake the bottle while spraying, if empty it will not feel or sound like there is liquid inside.

Was this Answer Helpful ?Thank you for your question. As the product is being applied; the chemical is siphoned from the container to mix with the water. The level in the container will decrease and the bottle will empty.
