If there are envionmental reasons for a pesticide ban, then the bad results would not be immediately obvious. The annoying thing is that commercial growers are still allowed some of the chemicals banned to the rest of us, even though we would use them on a small scale and in a very targeted way.
But in practice I can't imagine even the UK police knocking on my door to ask what precisely I was hoping to achieve by putting coffee grounds on my flower beds. If it's lawful to use as a soil conditioner, it can't be harmful as a pest deterrent.
I think the trouble is that there's some blanket rule saying that any substance used to kill or even deter wildlife has to be approved. This is where it gets silly, as some creatures are deterred by harmless substances - and some, like slugs, are not likely to be an endangered species anywhere!
