Ingredients:
- one cup flour
- two cups water (only one cup if you are making dough)
- one pack of dried yeast
Mix the ingredients. Add more water if it is too thick. It can be used right away, but it becomes more potent after 24 hours.
Pour some into a small dish such as a old yogurt container or tuna can. Sink it in the soil so that the edge of the container is at soil level. If it starts to dry out add more water as needed. If the top gets crusty, give it a stir.
The mixture is good for 14 days but in a heavily infested area you might need to dump it out more frequently.
Bread dough is toxic to pets so keep them away from the traps or cover the traps well.
Will sourdough discard work? It has not been tested but the researchers feel confident that it too will work.
