fungus gnats, BT {correction] -- more

As it turns out, Btk (Bacillus thuringiensis kurstaki) is effective 
against caterpillars which are insects in the order Lepidoptera (moths 
and butterflies).

But when it comes to fungus gnats, the appropriate Bt is Bti (Bacillus 
thuringiensis israelensis) which is effective against insects in the 
order Diptera (flies, gnats, midges, mosquitoes, and more).

Oops, I should have looked at the stuff before posting. THURICIDE is
Bacillus thuringiensis KURSTAKI. I also note, I actually used a Safer 
product called Caterpillar Killer (with the same BtK in it). The kind 
of fungus
gnats I had, spend part of their life as a worm in the soil eating 
things like
plant roots. ...
