Could I use only part of this product at a time and if so, how long could the remainder be stored and remain viable?

I ordered 2 packs hoping to use one after the recommended 2 weeks and and the life on both were only 9 days after I received them.

Does this work for fungus gnats?

Yes, this will get rid of fungus gnats (Sciarid flies) in your house plants very quickly! I divided mine into 3 portions and suspended each in 1L of water a few days apart & used this to water my plants. Just one day after the first dose, the gnats were gone! I also used some yellow sticky fly traps to catch the flies.

How many house plants will this cover? I usually need 15l to fully soak all soil.

I used it on indoor plants and it did well over fifty.
