But ideally for ornamentals you want a long acting systemic miticide that is compatible with the plants you want to stay alive. Tweaking the humidity slightly will help. If you don't care what lives and what dies then a sulphur candle is pretty good as a total knock down. But it will play havoc with the soft furnishings. OK in a dormant greenhouse though. Its a bit too late in the season to do anything effective now. Regards, Martin Brown |

Not very mite-like, but looked /just/ like a close up of a tiny one. No idea what it was, unless someone evil genius has been going round the garden with a huge enlarger gun! |

They can be quite fiddly - you can't use them until the greenhouse/conservatory is warm enough and by then the red spider mite may have built up to more than they can handle - or to more than the number of phytoselius you can afford can handle ;-) But at this stage of the season, in a greenhouse, the problem is going away - the red spider mite are breeding much more slowly. Not necessarily the case if your conservatory is kept warm all the year round, in which case you may do well with Phytoselius. How much have you got? If at very low levels, removing the worst affected leaves and washing others with soapy water can go a long way.
