Hi Andrew,
thanks for the ideas and tips. It's a particularly interesting idea about the nemotodes - not heard of that before i might have to do some investigating.
I keep meaning to put up a few critter hotels in the garden, I'll try to remember to bring back some bark next time I'm filming at the forest.

Stop slugs using eggshells by: Andrew
Another way of stopping slugs is to put straw around the plants especially strawberries as it also stops the fruit from resting on damp soil. Try to use good quality straw as some of the lo-cost hay/straw from Tesco blue stripe range (rabbit bedding) can start germinating. I used some last year and while it did keep slugs at bay, I ended up with a mini lawn in the container that the plants was growing in. Be aware that straw can attract Earwigs which do like a nibble of juicy fruit and veg.
I may go for the copper tape route as this is harmless for slugs but because a slug has a moist body as it tries to cross the charged metal, it receives a tiny electrical shock that is harmless to the slug but it won't like it. It's a bit like chewing a bit of tin foil with a mouth full of metal fillings.
Another high tech anti-slug method is to use nemotodes (microscopic worms) that are sprayed around the garden, flower beds and veg containers etc. These nemotodes actively seek out slugs and invade their bodies them thus killing them off. Completely harmless to humans and other wildlife except slugs. Using nature against nature is the best way. Earlier this year I placed small piles of old tree branches and cut logs around the garden to attract carnivore insect species such as the black ground beetle as they feed on slugs. If you can attract a Hedgehog into the garden it's even better as slugs are their fave food.
