[A/S] Pests

["joanne and jeff b." <temp4ident@xxxxxxxxx>]

  We recently took some friends out back, where our 1976 Argosy 
trailer is parked to show them how nice it was, and the improvements 
we had made.  To our embarrassment, when we opened the door, there 
was a strong "dead mouse" odor!  We searched every nook and cranny, 
but were unable to find the deceased culprit.
  We have now decided that it is probably better to "repel" pests 
than to put out poison and have them die somewhere that you can't 
find them.  
  We live in very northern Vermont, and our trailer is parked and not 
in use for a good portion of the year.  We have been looking at the 
electonic pest repellers and cannot decide if we should get the plug-
in kind that would mean we would have to keep electricity running to 
the trailer all winter, or the battery operated ones which we are 
afraid might not work when it gets to 30 below zero here.  Also, we 
don't even know if those things work at all, anyway.
  Does anyone have any suggestions?  We would appreciate any and all 
ideas!
