More ammo . that was too easy.
seriously though you will be vulnerable so your best bet is to be stealth and not let your position known.
no lights at night,or black out curtains, stay away from the windows.

heating of foods can make the smell travel a looong ways, no smoke etc
you might be surprised how long you could hold up.
your biggest issue would be disposing of your waste.
