Fungus Gnats behavior

Fri, 15 Apr 2016 23:30:26 PDT
Hi List,

today I've spotted more fungus gnats larvae on the surface of my 
seedling pots than usual - is this a sign that the nematodes i set out 
to hunt them down 3 days ago are at work, or is it merely an effect of 
this being a rather gray morning? I'm asking because if it's the latter, 
i'll grab my tweezers and go hunting, but if it's the former, the hunt 
would only remove nematodes from the battlefield...
