'Pam',
I am really at a loss here and somewhat annoyed to say the least.

Now, can anyone help to eradicate the red spider problem?

I agree with you Emrys ! Going OT is OK so long as the thread splits and the
original post does not become lost.

I too have wondered where pests suddenly appear from - lily beetles for
instance. They seem to home in from miles away!

Back to red spider mite. I don't have a clue where they come from but the
following sites may throw some light on the subject:

It seems they may de distributed by wind or that the eggs are already in the
soil of a plant brought into the G.H.

They seem to have originated in South America:

HTH (but at least it back on topic!)
