Glad I discovered this thread before attempting my outdoor project. Think I'll start my Lowryder yungins off in a rabbit cage to keep critters out. By the time they start flowering hopefully they'll be less appealing to rabbits, possums, armadillos & other small creatures in the area.
For insects I have Seven Dust, but will only use that EARLY in the grow if there's an acute insect infestation. Not too keen about using that on my plants but I hear it works so I can always just do a thorough flush before harvesting. Other natural repellent ideas I can use as a first-line of defense: human hair, human urine, soap shavings, aluminum foil around stalk (for slugs), garlic, sharp spikes & various essential oils. (This is not a guerilla grow in some forest but we do have a plethora of bugs & small critters like rabbits & gophers).
No deer, thank goodness, and no wild boars this close to where I'll be planting! Some of y'all have it ROUGH!
I would do all I could to avoid using seven dust as well as anything similar to it.
If you must use dust, go to the ag store & purchase some diatomaceous earth.
