Voles are rarely ever seen because they live primarily in tunnels and runways under the lawn surface. They construct numerous surface or subsurface burrows and tunnels (1″ to 2″ wide) in a relatively small area, which contain numerous adults and young.
Accumulated vole damage is apparent when vole populations are high. Vole damage includes girdling and gnawing of trees, vegetable gardens destroyed by eating of highly nutritious roots, damage to lawns by extensive tunnel and runway systems, along with tearing up mulch in flower beds. There are some health concerns with voles. Voles are occasional carriers of tularemia, bubonic plague, and are hosts to numerous internal and external parasites, yet voles pose no major threat because of their infrequent contact with humans.
