No-beer slug bait recipe (yeast trap).

Beer traps have long been used for slug control but there is another way to trap them that doesn’t involve you sharing your precious brews (because, really, why should slugs get the good stuff?). Try this very basic yeast trap instead:


1 cup water

1 tsp sugar

1/2 tsp dry yeast


Throw everything into a jar and mix it together.  (You can double or triple this recipe if you are attending Slimapalooza and require lots of bait. It’s best to mix up a fresh batch each time you need it).

Raid your recycling bin for some shallow containers and sink whatever you scrounge up into your garden bed so that the tops of the containers are level with the surface of the soil. In effect, you’re creating a drop of doom/swimming pool sort of scenario.  Pour the bait mixture into the containers so that they are about 3/4 full.  Then go crack that beer and enjoy the rest of your evening.  Slugs come out at night so check your traps the next morning and dispose of the contents in the garbage.

What are your tried-and-true methods to combat slugs?

  1. Wish I’d found your post sooner. Will definitely give this a bash.

    I introduced nematodes to our veg garden this week to fight slugs that have devastated our leafy greens. Has anyone here tried slug nematodes and have they worked for you?
