@Wanderer, LOL! "... small bells and smell of pepper."
I use little bells (I prefer a set of small bells which I can use as one "bear bell" or separately on my pack, food bag, etc.
HOWEVER, I use them on my pack so I know if some day hiker, or day biker, starts getting TOO curious about my gear while I'm sleeping (true story!) or if a squirrel gets too curious about my hanging food bag.
"BEARS"?... ya, I guess that's possible too. 😉
