i'm sure you'll get er under control rose
i'm always battling something OD here too (thrips few years a go, aphids last couple, and i just found a massive white fly infestation on my fruit tree *thought it was Powder mildew it was so white
)
i use slug bait and neem *though many here frown on neem.
oh and get some mint to plant nearby.. something about it, the ants don't like (i used it to try to stop the buggers from free ranging their aphids on my plants
)
what's life without a few trials though eh?
my grow is a mess ATM too. had to have surgery, so that kinda made my early run a little FUBAR. have one re-vegging on me now.. that's a kicker (don't even know what to do with it now) lotsa pretty sad looking plants, and no real plan what i'm going to do..
but i'll overcome.. all part of the fun
did you try to rough em up at all? have they responded well from their abuse atleast?
keep yer chin up.
