One of the most common pests in the garden, is the slug.
Slugs are very effective at surviving, yet we know so little about them apart from putting blue slug pellets down will kill them but damage the wildlife that feeds on them.

What we know:

• they hate gravel, sand, etc. course substances that get into their slime, they avoid
• you cannot drown a slug. I tried once, after ten minutes underwater, they had climbed out of the small pond we have and were back on their way to chomp on our veggies again
• they dislike the sun, heat, dryness

What I don't know about:

• how do they know the difference between vegetables and weeds?
• no matter how far away you throw them, they keep coming back
• apart from hedgehogs, who are their predators?
• Digging your soil over in winter, helps the frost kill their eggs, laid just under the top of the soil

As the old addage goes, "know your enemy" - any tips/information you can post will be gratefully received.
