Here in Indiana (and much of the south east US) we have, in addition to
mice, chipmunks, shrews, and moles, the vole...a sort of short-tailed
mouse...which eats the roots of most plants. All of their burrowing and
chewing behaviors around woody perennials are reduced by heavily
planting narcissus and daffodil within the driplines. All of them are
helpful in improving drainage in our heavy clay soils. The shrews are
predators on the rest of them. We definitely need more snakes and we're
improving their habitat with rocks and brush piles/berms and water
features. The steadily growing populations of frogs and toads encourages
snakes. Haven't seen rats but I have no doubt that they are around. Cats
abound in our neighborhood (we don't have any) but they don't seem to
have much effect on rodent numbers. Chipmunks also consume a wide range
of garden fruits and veggies.
Another strategy we employ is to plant our woody species with as much
coarse gravel around their roots as possible. Many rodents don't like to
dig through this material as it tears up their paws, especially if
something like pumice is used. The principle gravel available in this
region is limestone which cannot be used around blueberries and other
I haven't seen them nesting in mulch yet.
