I buy predatory wasp larvae every three weeks from March through mid October. Keeps the fly population WAY down in the corral and lean-tos. (Horses, cows, goats). They are a wonderful predator for flies, and don't sting. I wouldn't care if they were in my orchid grow space.

I'm not worried about them at all just wondering if other people had them. They seem to be immune to the pesticides I use anyways heh!
