Fungus Gnats

I love the concept that because Bacillus thuringiensis is 'organic' it is
somehow wholesome, environmentally friendly and thoroughly OK.  Kind of like
'natural remedies' for human diseases somehow not being 'drugs' - when the
active principles are really chemicals and drugs just like any that the FDA
approves.   Bacillus thuringiensis has a broad host range and produces very
potent toxins which kill all sorts of insects, beneficial and otherwise.  It
has many effects on the environment - just a bit different to using
'chemicals'.

Best,

John

Fungus gnats normally appear in peat based mixes. Why not to try a larger
portion of mineral origin ingredients? They would never appear in them.
