I trimmed back a miniature rose in a pot yesterday, and noticed it had tiny

They're very pale/white, I thought spider mite were red.

Red spider mite are at most pale orange and often so small you cannot
even determine the colour without a magnifying glass. Misting with water
and/or a systemic insecticide will probably see them off. They are only
a serious problem indoors and under glass. Outside is too harsh for
them. You are a bit up against it effective controls have been banned.

The truly bright red fast moving spider mites are the good guys!

I've seen them before and thrown the plants if I can't wash them off
successfuly, but this time they're worryingly close to the blueberries that
haven't been put out yet. I'm hoping I got rid of all the 'infected' bit
cos I pruned the roses right back (not sure if you're meant to do that with
minis, but they weren't looking happy at the time and were showing sign of
new buds, so it seemed appropriate. For 20p I'm prepared to throw them!)

The blueberries will throw them off outside even if they did pick it up
indoors so I wouldn't worry on that score. Cold damp windy British
weather really doesn't suit them.

Having said that my snowdrops get a specialised spider mite of some sort
every year that marks the foliage but doesn't seem to damage vigour.

I'm thinking maybe keeping plants on that window (which is very sunny)
misted may be an idea at reducing the problem.

Any thoughts?
