Whoa, the thread is taking a nasty turn for the worse. No good reason to do this over gnats.
The Bacillus thuringiensis in mosquito/gnat control products has a limited shelf life. I've purchased a case of Mosquito Dunks and experienced their loss of potency over time. The Bt based Gnatrol I purchased a month ago was on recommendations from this website but it had no apparent effect on a heavy infestation when used at the maximum dosage several times as a soil drench. I assume it was stored improperly or was past its shelf life.
In "alternative" news sites, I have read of concerns regarding Bacillus thuringiensis products. The bacteria somehow causes perforations in the gut lining of insect larvae when ingested. Evidently this can also occur with humans according to the articles I've read. This concern was regarding GMO Bt corn which contains the bacterial genes that code for creating whatever it is (seems it must be a protein) that causes a leaky gut. So I myself wouldn't drink the stuff. But it would seem safe as a soil drench from what little I know about it. Bt products are sprayed on plants to kill caterpillars. Is this OK for foodstuffs? I don't know and I'm too lazy to spend the remaining coolness of this morning researching the subject. I'll definitely read whatever comes with my bottle of Microbe Lift BMC when it arrives.
