Well I have.
An evil Cabbage White has been attempting to reproduce on my sprout plants. (This by the way, just in case you're wondering, isn't some peculiar double entendre.) So, I've been chasing it away. I don't think it has noticed. And really, I can't bring myself to kill it. I am so lame as the kids would say.
Also I found Slugzilla munching on one of my lettuces last night (yet again, this is not some code word for deviant practices) and what did I do? Dunk it in a nearby water filled pot? Stomp on it? No, I put it in the bin and wished it good luck.
That said I had no qualms spraying the courgette plants to kill the Whiteflies.
But that's okay cause everyone knows they're bastards.
