I got the Slugs to leave my garden greens alone without the use of slug pellets after trial and error with other natural repellents

I tried the use of Diatomaceous Earth, watermelon rinds, Rose Rosemary, oregano herb, mint herb as coplant, and the bugasalt salt gun, none of which really stopped the Slugs eating my bok choy at sundown. However I finally came up with a $2 deterrent have her trial and error.In Metro Vancouver, British Columbia, BC, Canada. In 2020, the weather has suddenly become colder and more dab, making me wonder if the theory about the grand solar minimum is going to be true.
