Damage: Voles,
like most rodents, love to chew on things. The damage
they do will be at or just below ground level. In
southern parts of the
United States
voles do a lot of damage to
hostas.
In parts of the country
which receive a lot of snow, voles are often the cause
of the death of trees. They burrow under the snow cover
and find the base of a young tree. Since there is
nothing else to eat, the will chew at the bark and, if
they do enough damage, may girdle the tree causing its
death.
Rabbits may do a similar
type of chewing damage but their bit marks are larger
than the voles plus they will chew off small branches in
a single bite while voles must nibble with their smaller
mouths. Vole tooth marks will be about 1/8 of an inch
wide by 3/8 of an inch long, much smaller than a rabbit.
