If ur worried bout mites and gnats. Try Azamax. The small bottle is like $20. U use 1 teaspoon, per spray bottle. I still have a half full spray bottle, with a full bottle of Azamax. Wayyyy better than neem oil. 100% natural. Made from veggies and plant extracts. Kills them in seconds. And they wont come back. I spray the top of my soil also, cause Subs Supa soil attracts ants. Aint seen one yet!
