Yes, citronella is a thought. I have some. Do you think essential oil would be effective as a cure rather than a preventative measure? I might try the garlic too. I've tried washing up liquid which either does or doesn't seem to work. Perhaps it depends on the make. I know ladybirds would quite happily hoover them up but I haven't seen anu around recently.
later-just google, resulting more suggestions. Any more ides welcome with thanks.
