Slugs can be a real problem in the garden, as well as really grossing you out!
Here is a recipe for a slug attractant.
1 teaspoon brewers yeast
1 Tablespoon sugar
1 Cup of water
1 large shallow dish, I use the lid from a large jar of mayonnaise or peanut butter, or something similar.
Mix it all up together.
Place the lid in your garden near where you are having slug issues.
Fill with Slug Brew.
The idea here is that the slugs will be attracted to the brew, crawl into it at night, which is why the container needs to be shallow. The container can be easily discarded come morning.
If you can set the lid into the garden right at garden level it should help in making it as easy as possible for the slugs to get into the trap.
I have heard that people simply use beer, instead of mixing up the recipe here, but I haven’t tried it. I believe it should work though as it is the yeast, which is in the beer, that will attract the slugs.
