Need to plant one for you and one for the bugs for good organic gardening, but with no space it's hard to achieve that! I thought I had caterpillars on my last tomatoes, and found it was baby snails up the stakes!
For the people with treated timber around the beds, it's useful to know that it's proven that worms remove the arsenic from soil, so it's very useful to attract native worms to your garden. The way to do that is by using a lot of composted materials, no chemicals, and keep well mulched too. Using a worm farm to produce vermicast helps, as the native worms will also happily come and live in garden areas that are full of good organics with other vermicast too. You'll bring them in from all the neighbouring properties that don't have such attractive soil as yours.
You can see the websites I put up earlier in the thread for more info on getting DVD's to learn more and get your own worm farm going too.
