OK, for no charge here are two tidbits of information;
#1 all rodents like to knaw/eat the insulation of all types of wiring BECAUSE the
oil that the insuilation is made from is the same
oil as Peanut Butter! Yes they will "die" for peanut butter!
#2 and the best hint is "Mothballs". Rodents of all types can not tolerate the smell. When we stored boats for the winter mice/rats etc., could and did thousands of dollars worth of damage to the wiring and the interiors. After "X" number of complaints an insurance agent told me to scatter a few Moth Balls in anything we stored. Problem immediately solved and have never had that problem again been nigh onto 15 years now....Catch them with peanut butter- make 'em run with Moth Balls!
Just another of my 2-cents worth...
