short pieces of garden hose make great slug traps - honestly !
put them in a damp place - underneath plants - ; the slugs like to hide in dark places after a night's meal . make sure the bottom of the opening is just a fraction below ground level , so that they can easily slide in .
next morning you pick up the pieces , dump out the slugs into a pail of water with a drop of oil on top : PRESTO !
you can also use the left-overs to make rings to hold bushes in place - better than rope .
finally : they might make a "trickle hose " . put lots of holes in the longest piece , attach to faucet , place overnight in garden and let the water trickle - turn the tap on just so .
you'll probably need more punctured hose than you have now . just let mo know , i'm sure he'll be glad to assist
