ive only used the sns203 mixed in water an drenched the soil..i never have used that diatomaceos earth on gnats so i wuddnt know..but it werks good by itself ..GL
Tha6t shit works! Thanks for sharing this product. With Mosq.bits it took a lot of drenching . This was single application and organic so it does not mess with microbes. Big fan so far!
