Dollar Stretcher gives you ideals on ways to say money. The one tip that caught my eye talked about using cayenne pepper. We all know cayenne pepper is used as a seasoning but putting it in your socks to keep your toes warm when your outside for a long period of time, not for sure....
You can also use it as an inexpensive pest repellent. Place a couple of teaspoons into a spray bottle, fill with water, shake and spray. Specifically, animals such as rodents do not like it. Spray in suspect areas, including the garbage can. It's natural, inexpensive an quite a deterrent.
Not for sure if I would shake a little in my socks before heading outside to shovel snow. I usually put on an extra pair of socks. Would your toes be stuck to your socks after a few hours? yuck!! Then you'll have to wash your feet and then wash those hot smelly socks. No, thanks. If I put anything in my socks it would be rose petals..........
