Dcpac Posted July 13, 2014 Report Share Posted July 13, 2014 I have a few Dhh larvae that are still in the substrate they were in when I bought them. It is time for a sub change but there is a lot of gnats in the current sub. I know you are supposed to mix 20% or so of the old sub with the new. If I cook it will kill the gnats, but also the good bacteria right? Would freezing it kill gnats and mites, but leave the good bacteria ? Thanks, Steve Quote Link to comment Share on other sites More sharing options...
muddymire Posted July 13, 2014 Report Share Posted July 13, 2014 Deep freezing, possibly. I know this is a point of contention for a lot of people. I cook it. I recommend drying it for a few hours in the oven at a low tempature like 125, and then rehyrdrating. Others would know best. Quote Link to comment Share on other sites More sharing options...
