Had a problem with caterpillars on my outside plants . My girls ARE in a plastic greenhouse . I shared benificial bugs with a buddy . You all know the drill . The basterds hatch on your buds and poop and cause mold ! I live in Ventura county Ca. Up the road from me is a company called "Organic Pest Control, Biological Solutions for Pest Management, Rincon Vitova Insectaries" I bought "lacewings AND wasps" . NO CATERPILLARS ! No poop no mold ! Try this out before pesticides !
