Subject: Re: [Aroid-l] Spider
Mites
Predatiory mites known as 'persimilis' are extremely
effective. I had the worst outbreak of spider mites I have ever seen in my
shadehouse, nursery stock and garden last (Aust) summer and they cleared up the
lot in a few weeks. I still haven't seen a single spider mite after 5 months.
In terms of safety,
effort, result and cost they are far more effective than any spray!
