Why is vole damage to subterranean plant parts often mistaken for disease?
Answer
The plant dies without visible surface signs of animal interference
When voles feed on underground storage organs like bulbs or primary roots, the physical destruction of the plant occurs entirely beneath the soil level. The gardener or observer does not see the animal or the initial damage. Because the plant simply wilts or dies as if it were suffering from a root disease, wilt, or a failure to transplant correctly, the true cause—a small mammal chewing on the roots—is often overlooked or misattributed to non-biological causes.
