Does this work to rid of gnats?
Demon WP is not labeled for gnats. We would recommend Bifen IT. It is a general insecticide and dries clear. It is labeled to be used indoors and outdoors as well. The residual indoors is up to 90 days and up to 30 days outdoors. Please let us know if you have any additional questions.
