I notice your raised beds are similar to my 3M x 3M bed in my garden and I too battle with slugs. Even after nematode applications and regular night-time garden sorties to catch them, last night I found 20 or so of the critters but not in my raised beds. The defence in part I am sure is due to copper piping attached all around the edge. So, the 20-30 types of vegetables I'm growing this year are safe-ish. One night I did find a brave slug stretching more than double it's body length over the piping to my young pea plants but not getting right inside the defence!
