3 Carefully prune and dispose of heavily infested leaves or buds to prevent the mites from spreading to healthy parts of the lily.

Low Humidity and Environmental Stress

Oriental Lilies prefer moderate humidity; extremely dry air can trigger a stress response in the plant. While not a direct cause of webbing, it makes the lily significantly more susceptible to opportunistic mite outbreaks.
