Hiya
It hasn't got to a stage to cause worry at the moment as I've only seen one or two slugs on sides of the terrarium, some eggs (which were chucked out of the window) and the odd young sliding around. There doesn't seem to be any damage caused to the neps in the terrarium aside from the odd notch in a couple of leaves and it has only been the boston fern that got munched which has now bounced back.
Would it be an idea to let loose some nematodes into my bio-active setup to prevent a possible slug problem? If not, is it possible that there is another way without disturbing the whole setup and harming the clean up crew?
