We enjoy feeding the birds, the squirrels (we have fox squirrels, red
squirrels, and pitch black ones).
We put feeders around our deck and it's a delight for us to watch them all.
There's a problem though with chipmunks. They like to eat the food too.
That's ok, but the problem they cause is digging tunnels all over my wife's
flower garden.

Does anyone know about any substance I could put in the chipmunk holes that
would encourage them to go somewhere else.
