Row-dents and their nasty chewing habits

[steinbru at vnet.ibm.com]

Anybody have a good way to discourage mice and other chewing critters
from invading the underhood area?   Stongly discourage!

Whilst checking antifreeze recently I see that (apparently) the
sweetness of ethylene glycol became an incentive for some pesky field
mouse to chew into my upper turbo coolant line connecting hose.  There
was also extensive use of the hood liner mat to line the accompanying
nest.  I'm not sure why, but plug wires seen to be nibbled on too.

Arrrrgh!  Any BTDT that really works?
