How do you keep mice and bears away from your cabin when you're away? My house is in the forest and it's a stone cabin. I left for a month and came back to find my roof broken by a small bear and a mice infestation that ate through some food and chewed through my nice bags. I stored most of my food in a metal container so that was ok but I'm curious to know how to keep animals from invading your house every time you're out. Is there some electric device I can turn on and leave?
