So theoretically the fungus gnats will disappear after some time in dry soil. True?
I have some in my tomatoes. I was planning on reusing this soil as a filler with fresh soil for later plantings. If I do indeed let this dry out for some time will ALL the larvae be destroyed?
I just keep getting them back I don't now where they are coming from.
I may just save this soil for outside plants later in the season not for indoor starters and such. Or it may go in the garden/compost. I have several 5 gallon buckets worth so it's not going to waste.
