I have a plot rented in a community garden and we are 100% organic. I am learning as I go. A fellow member told me that there were some slugs lingering near our compost bin which is about 70 feet away from my plot. She said to go ahead and set some beer traps. My question is, if I am not having an issue yet with the slugs do I still need the set the traps? Or will setting the traps bring them over to my plot possibly causing me problems? For a plot that is 4x20, how many containers should I set out? I have some medium sized yogurt containers that I was going to cut down for the trap. Thanks in advance for your advice and happy 4th!
