Montain House in itself is not going to keep the bears away.

A few things come to mind when it comes to camping in bear country.
Location:
Although you can encounter bears everywhere they generally travel where effort is less, or the chance of finding food is better. So do not camp right next to established trails, human or wildlife. Do not camp near vegetation that might attract bears (berries). Do not camp immediately next to a creek, as that appears to be a favoured travel route for bears as well. Think twice about using established camp sites, because you do bot know what previous users have been up to.
Keep a clean camp:
Game bags far away from your camp, yes, that makes sense, but also hang ALL your food and smelly things far away and (hopefully) out of reach. I say hopefully, because very often I can't find any tree or other structure that is really suitable. That includes things like toothpaste, apparently bears like that too. That also includes your empty mountain house packages, wrappers, etc. Don't burn your empties or left-overs in your camp fire, they will smell it. I've done it, and have found that something had dug through my campfire and located the alu remains, when I returned at night. I go as far as to not brush my teeth next to my tent but walk a little ways away. It would also try to get blood-covered clothes outside of my tent and away for the night.
Maybe this sounds extreme, but it's kinda useless to do only half of these things. Once you get used to it, it just becomes second nature.
Have fun out there!
