That would be my method.
I've tried saucers of beer here, but it rains too much and doesn't work. The slugs have a party, and go their merry way home afterwards.
Being an avid recycler, I have a few wine bottles from time to time.
I go to Walgreens, and buy the cheapest beer in the area, $2.99 for a six pack, and I pour a few ounces into each bottle, make a small depression in the ground for the bottle to lay on the side with the lip of the bottle even with the soil, and bob's your uncle.
Once or twice a week, I just upend the bottles, at a distance from my nose, and then refill. I have about half as many this year as I had last year, which means I still have a hellacious number of them, but I really can see a difference in my flower beds. My vegetable beds aren't planted with much yet, and I'm away from home right now, so it's harder to tell. But my peas looked amazing when I was home a week ago.
Hope this helps you out. Where are you from, macbettz? I was born in Meriden. I never saw slugs there.
