OK to but BT in Compost Bin?
Posted: Thu May 03, 2012 4:42 pm
We have a fly problem in our compost and as one of a number of steps to address it, I added in some BT (Bacillus thuringiensis) -is this a good idea? will it work? are there any downsides from trying?

Which Bt did you use? And what kind of flies?
Bt Formulations That Kill Mosquito, Black Fly, and Fungus Gnat Larvae. Bacillus thuringiensis var. israelensis (Bti) kills the larvae of certain flies and mosquitoes. The main targets for this Bt are the larval stages of mosquitoes, black flies, and fungus gnats; it does not kill larval stages of "higher" flies such as the house fly, stable fly, or blow flies.

Often an excess of flies in the compost pile is a sign of too many greens and too much moisture.
I think if you add some more browns, stir it around, aerate and maybe put a loose cover over it if it is getting rained on all the time (we have been having tons of rain lately where I am), the flies will likely go away on their own.
