Will the rats/mice eat it?

Another rather basic question: is FP cable any less likely to suffer damage by nibbling than PVC?  Location is the semi-enclosed eating area in a camping cabin environment.  Cables are to be installed on roof truss timbers; basic plus emergency lighting.  Our resident farmer wearing his pest control hat, reckons the risk of 'critters' being interested in getting up there is quite low; there is no evidence of their presence in the area thus far.  As site management is highly resistant to a conduit system on the grounds of appearance, I have few options (and walking away is not one of them).  I guess I'd be happy enough using MI, but costs and borrowing of tooling would both be difficult.  Anyone in West Oxfordshire if that is the advice?

  • Should be fine IMHO. Mice like dark, hidden, and enclosed areas and seldom venture out into the open unless there is a specific food source to attract them. Mice might well run around at low level after food debris, but are unlikely to climb to the roof level.

    And if they DO nibble at the cables, damage should be seen in time to arrange replacement, unlike in a loft space or floor void.

    I might use short pieces of steel conduit for any small lengths at low level, against both impact damage and mice.

  • I have read, and it seems very plausible to me, that small rodents eat cables because they are in the way. So cables under the duvet of Rockwool are threatened, whilst those clipped to trusses or rafters are not.

  • What is wrong with using SWA?

  • Unlikely to get mice and rats at high level. But if you were thinking of running the cable along the top of the rafters, less visible, then Barn Owls or other birds with sharp claws and beaks might do some damage. They could be attracted to the rodents anyway. Might be best along the sides or bottom of rafters. I won't mention bats.

  • FP cables would be easy prey to rodents, as they are not very rodent resistant, being soft and easily chewed through.
