Jimmy's solution:
1.sleep in the nude
2. have a bright flashlight on your night stand
3. in the night stand drawer is a straight razor and a hand grenade with the pin pulled out half way.
4. on the stairs is placed freshly soiled diapers

In case of a break in :
the BG coming up he stairs will slip and slide and his cursing will alert me. Then when the BG makes it to my room door, I will be standing in the middle of the bed, illuminating myself with the flashlight. So far this has stopped the BG, so I have not had to employed the straight razor or hand grenade.
