Re: [nafex] Tree guards for borers

["dwalsh/wchase" <wchase@interchange.ubc.ca>]

Tha various tree guard only protect the above ground part of the tree.  The meadow
mice (aka voles) eat the below ground part of the roots.

In the PNW those meadow mice run in tunnels up to 6" below the soil level.  They
use the upper tunnels when it is warm and the lower tunnels when it is cold.

Actually I think I was told that they use the upper tunnels for moving around the
orchard and collecting feed and the lower levels for reproducing and sleeping.

I use traps with RAMIK to get the meadow mice.  They bring the bait back to their
nests, but I have to keep checking traps weekly in cold weather especially in
January and February.

I put chicken wire around blocks of nursery trees and the Ramik traps inside the
chicken wire.  Ramik is deadly to cats and dogs.
