<span class="link_user">@Mia_BIOTABS</span>, As I know BT has a lot of specimens and one is only dangerous on a very few species. That’s why they use it as a biological defense against mosquitoes in a huge scale, as well. The one I use (bacillus thuringiensis kurstaki) it is against caterpillars, no other thing is harmed by it. On the package it also says: it has no effect on the aquatic life either. By the way : today it turned out that Fusarium is my enemy this year. So my plants are doomed :(.
