The fact is that each variety of succulents is different. So if you don't know what kind of succulent will work, do some experimentation (like I did!) and see what happens. Because they're so small, you probably won't see the spider mites on your plant, but you will be able to see the damage. The offset should be removed from the parent tree. Give it a light shake or dusting to loosen any soil. Your succulent can only hold so much water.
