Any suggestions on the best way to keep rats out when parked up for several weeks please. I recently parked ours up for 6 weeks outside our home in Spain, we live out in the country and when I got in the other evening I was horrified to find rat droppings. No damage or anything eaten through thank goodness but what's the best way to keep them out? Poisen is out of the question, we have dogs and I don't want to kill them just want them away fromour lovely motor home! I am considering an electronic plug in rat deterrent. Any advice, suggestions, or personal experiences will be greatly appreciated. Thanks.
