Is the predatory rove beetle safe to use to control pine bark adelgid and black vine weevil? Our landscape company is recommending this but we are a LEED building and don't want to introduce a beetle that will do harm outside of our building if released.
Predatory rove beetles feed on insects in the soil but won't damage a structure to my knowledge. You can read more about their habits and diet here: http://entnemdept.ufl.edu/Creatures/misc/beetles/rove_beetles.htm.
I hope this helps.
