Bti, while it is a chemical, is a substance that is derived from a strain of bacteria that is found in most soil. If I'm not mistaken it is used commercially on organic farms.
It is not supposed to kill earthworms, honeybees, or anything else except a few species of flies.
I have been using it on my houseplants and spraying my wormbin with it (though not consistently in the worm bin). It has been quite effective where it was used consistantly. I plan starting more intensive treatment to the worm bin and will report any problems.
Neem oil is also organic and not supposed to harm the earthworms. It repels the files from the bin more than anything else that I've noticed, but that can be useful when you want to do some fly vacuuming.
I've added small amounts of cardboard to the bin but it just seems to attract maggots (and more flies). Perhaps I should not be spraying anything but instead add much more material on top. I could also leave the lid off to dry it out more.
Perhaps I can figure out a way to combine all of these. I will report.
