Hi
We have a peanut feeder which was hanging from, and resting against, a full
height larchlap fence panel.

We got slugs climbing up the fence to get at the peanuts, so last weekend I
put a block on the fence so the feeder free-hangs about 3/4" away from it.
Got up this morning to find two slugs on it, one with it's back half on the
fence, leaning across the gap, with its mouth parts grabbing a peanut
through the wire of the feeder !

Much as I admire their tenacity and effort, what can I do to discourage
them, without annoying the family of mice that live in the Ivy on the next
fence panel, and run along the top of the wall so they can hop down on to
the feeder ?

(I've put another freehanging peanut feeder up elsewhere so the birds can
get a look in !)
