They certainly can move around.
In my garden, they have spread quickly throughout the garden.
I tried a number of organic sprays, but none of them worked at all.
Thanks to Jills suggestions, I tried acetimaprid. That didn't work either, but another of her suggestions, thiacloprid has.
Although by the time I found some in a local shop, a lot of damage had been done.
Border earlier this year, before the mealy bug.
Same border to-day after clearing the plants the mealy bug killed.
Anisodontea capensis El Rayo, an argaranthemum and some ivy leaved pelargoniums behind the pond, soon after planting.
The same area, after the mealy bugs.
Next year I would like to use neem oil.
It has proved impossible to find it here on Crete.
I can only find tiny quantities available on the internet.
If anyone knows of where I could find it in litre sized bottles, I would be most grateful.
